Cisco AP541 Issues.... (DHCP, Multicast, etc...)

RegardsHello everyone,
I bought the AP541 since I thought I might just as well take the plunge and get a "real" AP rather than the Netgear 102's that I had in the past
( and been working perfectly fine I might add ).
First issue is DHCP - I just cant get an IP from my W2K3 server and or router... so I call Cisco and Cisco tells me to call my wendor and my wendor
tells me to call Cisco...
Eventually I find out that if you do a registry hack on W2K3 and disable the multcast/bradcast limit in the AP I actually get an IP.
Weeey - Happiness.... for a while... but whenever I use my IP TV (which uses broadcast) I loose connectivety to the AP *bummer*
Oh well... I will soon get a Cisco Switch where I can manage the broadcasts so no biggie....
Well - turns out the IP TV wants the IP from my router/modem and not from my server which means I'm back to square one.
AP wont "pass through" DHCP requests and it will "die" on excessive multicasts/broadcasts.
Ironic how a $70 AP does just fine and a $500 Cisco AP makes you want to throw the thing out the window.
Thoughts / ideas ?
Regards,

What firmware version are you running? I recently installed one of these and upgraded to 2.0.0 firmware and I don't have the DHCP problem. I don't have Multicast in the network so I can't comment on this issue.
However I do have a strange problem with a network printer that I use on the network though. I can't print when I'm using the wireless network (enabled by the AP) but I can ping the printer from a wired device.
Also, pings to the printer don't work from wireless but they work from a wired connection. But I can access the web management console of the printer! Very strange. It's almost as if the AP is filtering in some way. I have the WAP connected to an ESW500 switch and I suspect it may have something to do with the smart port setting on the ESW500 when the AP is connected. I can't find a way to force the port settings to anything other than AP through CCA (ver. 3.0(1)). I don't have the ping issue when the AP is connected through another switch but I still can't print to the printer when on wireless through the AP. I didn't have this problem with a regular linksys AP/Router. I'll have to do some more investigating to isolate whether the problem is the AP or the switch or both.
How is your AP connected to the rest of the network? Are you also using a switch with Smartport configurations?

Update:
I logged into my ESW500 switch and forced the port that the printer is plugged into as a printer role (this is not available from CCA). I still could not ping the printer. I then configured the port the AP is plugged into, as a switch port and not AP. Voila! I can ping the printer. I had to remove and re-add the printer to be able to print though. So the problem seems to be with the Smart port definitions for APs. CCA now alerts me that I have an error in my configuration because the smartport definition is incorrect for the port the AP is connected to.
If you have configured smartports on your switch for your AP, try forcing the switch role and see if that solves the problems you are having.

HH5 won't issue DHCP addresses to new devices

My HH5 has stopped issuing DHCP addresses to new wifi devices. It not a problem on laptops etc, as manually entered addresses work but it's a no go for smartphones. Existing wifi devices continue to work ok.
I've reset to factory settings twice with no luck but trying another router linked to my old white VDSL modem works fine.
Anyone have any ideas?
Thanks, Roger

This is not a large scale deployment.
If you want to test & see the difference you can create DHCP pool either on your DHCP server or WLC connected switch.
It does not make sense defining DHCP at different places if you have a proper DHCP server. (typically WLC DHCP use for guest services where WLC placed in a DMZ where no direct connection with other corporate services & from security perspective you do not won't to mix these traffic with your corporate traffic)

Cisco SPA502 G - DHCP & Call problem

    Good day.
     I have many cisco spa 502G phone in my network which working correctly. But one phone doesn't working via DHCP. If I using static IP, I can ping phone, or login in on web-interface, but when i was trying upgrade firmware through Firmware Updater, I see error - upgrade failed, No Response From Spa. Phone firmware version is 7.4.3a .
     End the most important problem is that phone can't work correctly with my asterisk-server. If i receive call from anybody, i can do this only system keys nearly phone-screen. I can't call from this telephone ((
Please, community help, and sorry for my english

Hello Sergey,
To wich firmware do you want to upgrade? For some firmwares you have to do this in steps, you can not go directly to 7.5.4 form the frimware that you are using.
When you put the phone back to DHCP can it be that the phone tries to get an ip adres that is allready in use. Chek the DHCP pool etc to check the leases. At our office some phones say that they are initializing network for a long time and when we check the problem is that the phone wants to get an ip adres that is allready in use.
You can check your other phones web ui to see if an duplicated ip adres is causing the problem that you can not use the phone with DHCP.
Kind Regards

Issues with Multicast MOH with CUCM SRST Sites

Hi there,
I am having an issue streaming multicast music on hold at remote sites by sourcing the music on hold from the local flash of the Cisco 2951.
I am running CUCM 9.1(2) SU1, I have 1 x PUB and 1 x SUB. I have enabled the PUB to stream unicast MOH and have enabled multicast MOH on the SUB. Base IP: 239.1.1.1 and Port 16384.
I have set the MOH Region to all remote sites regions to G.711 and have put the SUB into an MRG and have enabled MOH at the MRG and Audio Source Level as per documentation. The MRGL for remote sites contain the local sites hardware resources such as MTP, CFB and XCODE. Second to that MRG, I have set the MOH_MRG containing the SUB enabled for multicast.
When a remote site user put the PTSN caller on hold, I can see an active multicast music on hold session active on the local router but the PSTN caller hears silence !!! The number of In/Out packet on the multicast session does not increase at all.
Could you please help me guys? I have tried all options and still I am getting silence all the times.

Hi Rachel,
The IP address CUCM selects is based on the codec and the audio stream.
See the following URL. http://voiceonbits.com/2010/06/29/moh-issues-and-resolution/
I borrowed this table from that URL and cleaned up the port numbers. Hopefully this helps.

I've been using LR with my Nikon D3200 for a year or so. Shooting in RAW/NEF no issues with import etc until I updated LR and now I can't get LR to allow me to select when I try to import. It does show the images but they're grayed out and not able to be selected. Any thoughts? TIA

Greyed imaged in the Import dialog box mean you have already imported the photos into Lightroom, so there is no need and no benefit to importing them a second time.
Just go to the Library module, search for the desired photos, and resume working on these photos.

Question # 2--how to avoid the DHCP conflict issue, double NAT, etc.

I'm having a tough day wasting hours working on the TC. It once worked fine for a year. Now, I'm struggling to maintain a connection at all.
I may be doing this wrong but I'm using two screens to manage this.
1. preferences/network
2. the TC internet connection settings
I had written all of my settings that worked on a piece of paper. Now that I've had to reset everything earlier today by plugging/unplugging stuff per Comcast orders, I'm wondering if all of my previous settings are worthless.
Reading possible solutions on here I tried to set the connection sharing to bridge to avoid the double NAT issue. This resulted in a message that more than one computer had the same IP address and I couldn't access the internet so I went back to sharing the public IP address like I had before.
I had, and I'm trying to have now, IPv4 configured manually. When I use settings like I had before, it tells me the DHCP range is invalid. If I increase the 3rd digit/group of numbers to change the range, it re-boots but I'm unable to get to the internet.
I don't know what I'm doing wrong. Any help?

Thanks to you both for responding. I had actually already read that Networking 3.0 document ... and since options 1-3 were not allowing the QuickVPN to work and options 4+ resulted in lost FIOS TV services I wasn't pursuing any of those options. Out of all of them it sounds like Bridging the Westell would be closest to what I want (enabling the Cisco router to acquire the public IP address). But I'm not willing to sacrifice my TV functions so even that option is a non-starter for me.
Over the past two weeks I have spent some 30 or 40 hours researching and then tinkering with the configuration on the routers (and VPN client software -- QuickVPN and shrewsoft VPN client). So I just invested about 15 minutes in downloading the free TeamViewer software. And although I didn't want to go the "3rd party software" route I'm actually glad I tried it. I now have a working VPN connection via TeamViewer, and through the VPN am able to use windows remote desktop just fine -- which was my goal all along. I'm concerned about the 3rd party software / security ... but at least this works. And I can always disable the TeamViewer Service when I'm not using the software.

Cisco Phone 7937 DHCP lease issue

Hi ,
We have configured DHCP lease id 8 day. But Cisco Conferance Phone 7937 is taking DHCP lease for only 1 day. Can any one know the reason

Firmware 1.4(5) is available for the 7937. The release notes don't mention your problem, but there are other DHCP fixes in the firmware.
http://www.cisco.com/en/US/docs/voice_ip_comm/cuipph/7937g/firmware/english/1_4_5/release_notes/7937_rn_145.pdf
I haven't seen anything like this with our 7937s. Have you Wiresharked the phone, to be 100% sure what the phone is getting via DHCP is what you think it should be getting?

An E4200 "MegaThread" - FAQ, Issues, How to, etc

Hi Cisco Community! I've taken it on myself to make a kind of "mega-thread" for the E4200, because I see that there are a bunch of questions scattered around the forum, and (perhaps it's just me personally) I'd love to see things grouped together as one nice reference. I'm new to the forum, and to the E4200, but I'm loving it so far. I'm not a forum mod or anything like that, I just thought it'd be nice to gather the issues/questions that Ive seen.
Let's talk about the E4200!
The Cisco E4200 is the latest high-end consumer router from LinkSys/Cisco, released in January of this year.
**Whare are all of the vital stats for the E4200?
See this web page: http://homestore.cisco.com/en-us/Routers/Linksys-E4200-MaximumPerformance-Wirelessn-router_stcVVprod...
**Which hard drives / flash drives work with the E4200?
Here's a "tested" list: http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&app=vw&vw=1&login=1&docid=0542deb2fe8c469383f8c59723d2...
Basically, any external drive (including ones you put together yourself) should work with the E4200, as long as you're using a drive formatted in FAT32, NTFS, or HFS+.
**Can I wall mount the E4200?
No, there are not any screwholes in the bottom of the device. It's a common question though, because Cisco hasn't released any pictures of the bottom of the device.
**Can I use a USB hub to connect more than 1 hard drive/flash drive device to the E4200?
No, the USB hub will not be recognized by the router, therefore, the devices connected to the hub will not be recognized.
**Why is the light on the top of the router blinking?
Most times it's normal, and I list normal operation below. HOWEVER...
There seems to be an issue in the 1.0 firmware that's been reported in these and other forums. There is a concern that this is a security risk. The thinking is that the router is stuck in "Wireless Protected Setup" mode, and waiting for connections. Some / several users have reported that turning OFF WPS and going to "manual" mode (page 12 of manual) fixes the issue. CISCO HAS NOT COMMENTED ON THIS ISSUE, and we REALLY want some information.
You might get a blinking light that doesn't mean anything. The blinking light, either in error, or as a part of normal operation, doesn't seem to affect performance.
Here's the "official/normal" reasons the light blinks:
Wi-fi protected setup- When you're setting up a device, it's supposed to blink every two seconds. If there's an error, it flashes quickly.
Upgrades, Resets, power on - The light should flash slowly in these conditions.
**The logging functions aren't working the way I expect / aren't working.
This is also an issue that has been reported in these forums. So far, it's unknown if this is an issue with the firmware, or how people have configured their routers. At a minimum, the logs in this device are a lot more "skimpy" than other routers on the market.
**What issues are Cisco / Linksys aware of?
Check this page: http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&app=vw&vw=1&login=1&docid=3ba1589dc0734ff7978c9e9203d0...
Most of the issues that Cisco are aware of are display issues with the internal Web interface, for instance, you can make a wireless password long enough to break the layout of the page.
**The Web interface shows two wireless networks, with the same name, is this correct?
YES, always make sure that the 5Ghz network and the 2.4Ghz network have the same name. If you're using manual setup for shared keys, make the keys the same. This enables your clients to roam between the two network types without reconnecting.
**The router is hot. Is this normal?
The processor in the E4200 runs hotter than room temperature. In the first month or so of release, some people have reported that the router runs "hot" - most experience that the bottom of the router is warm to the touch.
**I'm comparing routers - which is better, the Netgear 3700 series, or the Cisco E4200?
You're in a E4200 thread, we're a bit biased. But as objectively as possible, it's my recommendation you check out the E4200.
Netgear's 3700 series routers are currently experiencing several firmware issues (1.0.0.6 in the v2 of the router, 6.98 in the v1 of the router). These issues are causing disconnects, slowness in the DLNA server (USB hard drive connection), and several versions of the device's firmware have port forwarding issues. That said, the 3700 has some highlights over the E4200:
1. You can flash the firmware to an open source firmware. Several are reporting that fixes many issues, but is more complex than the default interface. It's also a "power user" solution, so be comfortable with your know-how before attempting.
2. There's a few "known good" firmware releases for the 3700 that solve issues, but they are only compatible with the v1 of the 3700 (mostly off the market by now).
3. The web interface has more options in the 3700.
4. The forum community at Netgear seems to be really good.
The E4200 has been generally very well recieved, has had two issues that don't seem to affect performance (blinking light on top, logging failures), has a 90 day return policy, has a wireless download throughput of over 50M (blows away all other routers in this class), and generally speaking, out performs other routers in wired tests (anecdotal reports from forum users). The E4200 also has a couple more options than the 3700, like being able to translate a port when doing port forwarding.
The E4200 is much newer than the 3700 series. It's generally accepted that we'll start to see more issues soon, as more people adopt the product. Those issues COULD be deal breakers, who knows.
Several people are taking a "wait and see" approach right now, but others (myself included) jumped from the 3700 to the E4200 because of gaming and other issues. Anecdotally, I love the E4200!
Some folks are waiting for the next Netgear router, the WDNR4000. I needed a router now.
**There are several screens under Storage. What does each do?
Disk- Disk makes a Network share (SMB share). This is good for computer devices on your network. Although you can make the shares authenticated, the default is that everyone has read / write access to the folders on your disk. The default location for your disk will be \\192.158.1.1\PARTITIONNAME (where PARTITIONNAME is the name of the share, which in turn is by default named the same as the partition; you can edit this name). This screen also allows you to remove the disk drive safely from the router.
Media Server- dedicated devices, like the Xbox 360, Playstation 3, several HDTVs, and more (including your computer) can stream music and video from your disk using the Media Server option. The router uses a service called Twonky to create a DLNA server that you'll see listed in the video tab of your Xbox or PS3. In this tab, you can specify how often the router should look for new videos on the disk, what to share, and what to call your media server.
FTP Server - You can also run an FTP server, for devices that can't access the disk any other way.
Admin - User management.
**Quality of Service - what does it do, how do I set it up?
QoS allows traffic through your router based on how important it is to you. For instance, if your games are more important than downloading files, you can apply QoS to ensure that traffic for your games always gets through despite the downloads.
QoS is automatically applied for wireless devices that support a standard called WMM. You don't have to do a thing to apply this.
For games, you'll need to add either applications or devices that get highest priority. If you have an Xbox or PS3, you can "set it and forget it" by doing a MAC address rule, and adding your Xbox/PS3 as the highest priority device on your network. If you want fine grained control over ports, etc - check from page 38 of the manual for details on configuring your applications. If you don't have the manual, it's available for download here: http://homedownloads.cisco.com/downloads/userguide/E4200_V10_UG_NC.pdf
**How do I get an "Open NAT" on Xbox Live / PSN with this router?
Many users will be plesantly suprised that the default settings of this router allow both the Xbox and PS3 through, usually with zero issues on NAT! That said, if need be, you can do either Port Forwarding or Port Triggering.
Port Forwarding - use this if you've added "Address reservation" for your PS3 or Xbox, AND you only have ONE (of each) in your house.
Port Triggering - use this if you have 2 or more Xboxes, 2 or more PS3s, and you need all to connect simultaneously.
Check starting at Page 36 for more information on Port Forwarding/Triggering.
On Xbox Live, you'll want to open the following ports: 88,3074,1863, and 53.
On PSN, open: 5223, 3478, 3479, 3658
Check http://portforward.com/cports.htm for more games / information.
**Does anyone know how to check what devices are connected to the E4200 via WIRELESS?
Go into Status -> Local Network , and click on the "DHCP Client Table" button. (thanks kirkh)
**How does Guest access work?
Guest network access is an unencrypted wireless network that does not have access to your LAN. You can assign the guest network any password you choose. When a user connects to the guest network, they must then load a web browser. When they load the web browser, they'll be asked to enter the guest network password.
Guest access is defined in more detail in the user manual, page 18.
*****Conclusion*****
I'll post more as more questions / items come up. Unfortunately, we can't edit posts, so please note that information in this post is as accurate as I know it to be as of 1/25/2011.
I invite other forum members to post question / answer format items, or generally discuss below. I hope this helps some people, and I hope this doesn't seem excessive.

**Does DHCP have to be on in the router to properly enable the Guest Network?
Yes. No DHCP, no guest network.
**How do I access the disk from iPhone, iTouch, iPad, Android, or Blackberry?
Any application which allows you to access network resources will allow you to access the file share portion of the shared disk. On Android, ES File Explorer allows you to access files, for example. There are several apps available on the iPhone, such as NetPortal. On Blackberry, try the FILES app.
**Can multiple people access the shared hard drive at the same time?
Yes, I've successfully streamed a movie to 4 devices simultaneously without any drops!
**Port forward to broadcast for WOL (Wake On LAN)? I want to wake up my computer from the Internet, how do I do this?
The current method isn't the BEST, but it seems to work: You must reserve a DHCP address for the computer you want to wake in the DHCP reservation screen (basic setup page). You must also put in the port forwarding rule for UDP port 6 or 7 to that computer, port being depending on your magic packet software. Currently, this allows for the Wake On Lan to work as long as the ARP table isn't flushed. Because the magic packet is supposed to be pointed at the broadcast address, it's important to open the port to the broadcast address, but the JavaScript on the port forwarding page disallows this action. Some people have intercepted the HTML on previous LinkSys routers (on the port forwarding screen) to... Forum members will likely be trying this method on the E4200 soon - I'm not going to, as I don't have a need for WOL (let me know how it goes).
**Is there a way to transfer settings from an old router to the E4200, like port forwarding, WEP/WPA keys, etc?
No, there's no automatic way to transfer the settings. Many of your old settings (WEP, HAHAHA) are obsolete anyway.
**Is the E4200 DLNA certified?
If it's not directly certified, it doesn't really matter. The media server seems to work with everything I've thrown at it - Xbox, PS3, Media Center, etc etc Technically, the box and the ad materials all state "UPnP AV Media Server", not specifically DLNA, so it's probably not actually certified at this point. The server is TwonkyServer it looks like (the icon is the same T icon).

Cisco 300 - VLAN DHCP packets not passing

I am seeing a problem with our Cisco 300 switches. We use these switches as access switches, with a stacked 3750-G at the core, two 2960-S at the distribution layer, and about 10 300 Series switches at the access layer (10 port and 28 ports, all PoE).
We use Voice VLAN (VLAN 14) for our Mitel phones – there is a DHCP server on the Mitel system. Phones come up, get tagged VLAN 14 (LLDP), Traffic flows (including Broadcast for DHCP etc…). The system works, and has worked for months.
One day, suddenly, I find that all the Mitel phones on a particular access switch are not working. I look on the Mitel system and the lease on DHCP has expired, and the phone is stuck on renewing its DHCP IP address. I run port mirroring on the switch for VLAN 14 to see what is happening. The phones are stuck on DHCP discover, and I see the DHCP Discover broadcast packets on the switch but nothing else, no DHCP offer packets – hence the phone stuck at boot cycle.
I then do a port mirror from another access switch (that is currently working) – I can see the broadcast packets from the Mitel phones on the broken switch, but on this switch I can also see the DHCP offer packets from the Mitel system. I run two port mirrors simultaneous from the two switches (one working, one not) and I can see that the DHCP offer packets are not coming through to the broken switch. Panic ensues – I look at the distribution layer and there is no problem what so ever.
For some strange reason, the Cisco 300 28 port has stopped passing DHCP broadcast packets on a particular VLAN, even though they are being sent. I power cycle the switch – and hey presto, DHCP offer packets are coming through, and the phones get an IP address and boot properly.
I wipe the sweat off my brow, note the issue down and carry on my daily duties.
Forward a couple of weeks later, and to today. I have another phone that is showing the same symptoms, luckily it is the only phone on this particular Cisco 300 28 port. The same issue is occurring as described above. I gather as much diagnostic information I can then reboot the switch – but still no joy. I then remember that this switch is not directly attached to the distribution layer and instead gets trunked to another Cisco 300 28 port. I give that a reboot and 5 minutes later, DHCP broadcast offers are passing and the phone boots.
I am listing this problem as not just a ‘one off’ now, and is recurring. It has happened to two of my 300 28 port switches.
All Switches running 1.1.2.0.
No link to up time – first instance of the problem, switch was up for 14 days – second instance (another switch) uptime of 39 days
LLDP is working fine on the switches, as is Voice-VLAN (Port is tagged and broadcasts out DHCP Discover which is seen by other devices throughout network)
Nothing in the log file on the access switch
Nothing on the Dist/Core regarding STP – Spanning tree set up is fine throughout
Has anyone else experienced same? I’m hoping this is a bug that is getting fixed.
Many Thanks
Tim

Hello Tim
Brayton Hackworth had a similar post as yours, found here;
https://supportforums.cisco.com/message/3684179#3684179
Brayton is using the Mitel 5330 phones where the LLDP no longer fed VLAN information to the phone network. But, he reverted to use a DHCP server to provide the VLAN information.
Unfortunately, I (personally) cannot test any Mitel resources (since I don't have them) so my labs usually only consist of either 7900 series or SPA500/900 series phones.
The best thing I can really recommend to you is to make a package of data consisting of;
Topology which consists of;
Modem type
Router including IP
All devices including IP of switches
Servers / relevant workstations
# of attached devices and # of users on the LAN
Switch config file + show tech on a notepad
Syslog output from the switch
Working PCAP
PCAP showing failure
PCAP legend showing what IP address are who (unless topology contains all IP)
Where the PCAP is taken from and method
We then can create a service request for you and pass it for review.

WLC2100 not issuing DHCP to clients

I've got a 2106 that I'm installing for a customer and having issues with it assigning DHCP to WiFI clients. What's odd is that this was working at one point at home during testing. Only difference at this point is LAN hardware at the customer location.
Simple config- single flat vlan on Cat2960G switch, ASA5505 serving up DHCP for the network. Wired clients are receiving DHCP fine.

I've run dhcpd debug on both the controller and the ASA and I see the DHCPD requests on the controller, but I never see them hitting the ASA.
I don't have the specific version of code it's running, but I know it's 6.0. One of my local Cisco account engineers found some Cisco CSC bugs referencing this issue. One TAC cas even referenced stripping all security off the WiFi, connecting the client and then reimplementing the security again.
Anyone have any suggestions? I'm hoping to head back over there again this afternoon to do some more troubleshooting and hopefully solve this for them.
Thanks!
Mike

In this case, the controller is not currently configured as DHCP server, although I may be trying that this afternoon.
I've currently got DHCP proxy enabled and am pointing it to the ASA5505 (192.168.0.1)- I thought I mentioned that in my previous post.
Please keep in mind this was working fine at one point in my lab while I was testing it, then I shut it down for a couple weeks while I waited to install it at the customer site. I've even tried resetting back to factory defaults and reconfiguring it to see if I'd accidentally misconfigured something.
I don't have the exact version, but I do know that I'm running a 6.x code rev. I'm probably going to just upgrade to 7.0 this afternoon and see if that makes a difference. If not, I'll try enabling the internal DHCP server, but I don't want to do that if I don't need to. Just one more thing to worry about managing for the customer.
Thanks,
Mike

WiSM Design and Testing Issues / Questions / Queries etc......

Hi all. Heres hoping you can help........
I hope you can grasp the following description of the test network I have. I admit a diagram would have been better but it's hard to send a whiteboard over the web : )
I am currently in the process of designing and testing out a wireless solution and am having a few issues / queries. I have a 6509 with a Wireless Services Module (WiSM) installed in slot 3, one Cisco 1240 AP on a remote LAN and a DHCP server on a remote LAN (not the same as the AP)
I am using LAG on controller 1 with port channel 1 and native VLAN 20.
VLAN 20 is 10.1.1.0 / 24
The management interface has IP address of 10.1.1.10
The AP-manager interface has IP address of 10.1.1.11
VLAN 11 is 128.88.1.0 / 24
The service port has IP address of 128.88.1.10
The Cisco 1240 AP on the remote LAN is picking up a IP address via DHCP (from a remote DHCP server) OK and can route to both the aforementioned VLANs 20 and 11.
Issue/Question 1
I can ping the management interface locally on the 6509 and also remotely from the AP so all looks OK there however I cannot ping the AP-manager locally or remotely.
Is this expected behaviour? I would expect that if I can ping one I should be able to ping the other or is the AP-manager interface not routed and only used in some way to create the LWAPP tunnel>
Issue/Question 2
As previously stated the AP is picking up and IP address but it is not being passed the Option 43 parameter from the DHCP server (not yet ruled out the DHCP server as the cause of this). Due to this I have amended the DNS entry of the management interface (10.1.1.10) to CISCO-LWAPP-CONTROLLER as a last resort. With a console on the AP I can see that the AP tries to join by the "%LWAPP-5-CHANGED: LWAPP changed state to JOIN" output but then get;
LWAPP_CLIENT_ERROR_DEBUG: spamHandleJoinTimer: Did not recieve the Join response
LWAPP_CLIENT_ERROR_DEBUG: No more AP manager IP addresses remain.
Is this related to the fact that I cannot see the AP-Manager interface on the network?
Issue/Question 3
I have chosen to hard code the IP address of the Service port rather than leave it to DHCP. I am more comfortable having static addresses for management. However, there is no option for a default gateway for the service port.... If I try to get round this by applying a static route via the CLI on the WiSM controller to point traffic out via 128.88.1.1 on VLAN 11 this seemingly overrides all routing on the controller and causes my management interface (10.1.1.10) to fall off the network. Is the routing table applied "en masse" to the Controller? If so this surely means that to use the Service Port you have to be on the local LAN segement?!?!
Thanks for reading my ramble and heres hoping you can shed some light on my "niggles" !

Hi
I am having exactly the same problem.
Getting the same error message "No more AP manager IP addresses remain."
I'm deploying 200 AP's that will connect to 2x WiSM (4 controllers) in 2 seperate C6k Chassis
(Controller 1a & 1b = wism 1, 2a & 2b = wism 2)
I have had 1 out of the first 5 AP's physically connected, come online and register with Controller 2b (btw: this was not the master controller, it should not have registed with 2b). All others fail with the same error message as above.
I have all Management and AP-Manager interfaces in the same vlan/subnet as my AP's.
I place a console cable onto the failed APs and see the AP cycle though the motions of trying to find the controllers, download new software code from a random controller, then it reboots, gets DHCP assigned, then get the "No more AP manager ip addresses remain" and then issues a "Reload requested by LWAPP CLIENT.
Then the AP does the whole cycle all over again.
Not sure why the AP's don't register with the controllers when they are all in the same vlan.
I have a couple of extra questions.
1. what address do you bind to the dns entry cisco-lwapp-controller.localdomain, is it the management address or AP-Manager address ?
I have bound it to the Management address for WiSM 1a.
Also I have 4x controllers (2x WiSMs, 2 controllers per WiSM). Do I just bind controller 1a's address or do I have to put 4x DNS entries into my DNS server for all my controllers?
2. DHCP option 43, Do I place all 4x management ip addresses in the option or do I put in the AP-Manager Ip address?
I followed this guide but was still a little unsure http://www.cisco.com/en/US/products/hw/wireless/ps430/prod_technical_reference09186a00804fc3dc.html#wp125304
2. This final question is more around Dynamic Interfaces for my 4 controllers once I get the AP's resisted,
Do I have to set up a dynamic interface ip address on every controller?
e.g.
Ssid = data, VLAN=10, VLAN10=10.0.0.0/24, I will bind AP's 1-8 to VLan group 10.
Do I have to setup 1 dynamic interfaces per controller in the 10.0.0.0 subnet, taking up 4 addresses ?
And if I only have to set up 1 or 2 dynamic interface, how does this work if the controller fails?
Cheers

Trunking on Cisco SF300 Issue

Hello Friends,
Issue: I have 3 Cisco SF300 multilayer switches, I have configured one switch as a core switch and changed the mode to Router (from layer2 to Layer3) and configured Vlans and DHCP pools accordingly, but when i am trying to connect another SF300 to this switch by using VTP it's giving error then i tried searching a solution and found that it does not support VTP protocol, can someone please help me on that, how i can connect other SF300 to this core switch by using trunking.
My goal is to connect the Switch1 and Switch2 to the CoreSwitch by using trunking so that CoreSwitch can advertise all Vlan information to Switch1 and 2. and PC connected to Switch1 & 2 on different Vlans can communicate to each other.
Network Diagram:
CoreSwitch fast-Ethernet port 1 to 8 are connected to Huwai Router Port 1 to 8 using a dedicated physical enter phase to connect each Vlan to the internet. using Nat overload. CoreSwitch's fastethernet Port 9 to 24 are disabled, gigabit port 1 to 4 are trunk port and allowed vlan are 11, 12,13,14,15,16,17 and 20.
Note: All 3 switches are in Layer3 mode.
CoreSwitch Gigabit ethernet Port1 connected to = Switch1 gigabit ethernet port 1
CoreSwitch Gigabit ethernet Port2 connected to = Switch2 gigabit ethernet port 2
Switch1 Gigabit ethernet Port4 connected to = Switch2 gigabit ethernet port 4

Cisco 3650 Issue with 1231 AP

hi all,
i've got an issue with a new cisco 3650 48 port wherein older AP 1231 keeps on disconnecting.
the connection is just a simple trunk.
#sh run int g1/0/47
Building configuration...
Current configuration : 62 bytes
interface GigabitEthernet1/0/47
switchport mode trunk
end
1231 is working fine on a 3560.
could someone advice if anything else need to do on 3650?

pre,
i don't think it's a cable issue. correction on the working AP, it's supposed to be a AIR-SAP1602E.
this AP is working on the 3650.
i've searched and i think the AIR-AP1231 isn't supported on this switch platform.
http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3650/software/release/3e/release_notes/OL3264701.html#18425
this new switch isn't friendly. first, i had the issue with PVLAN and now this :(

Finder Issues - List View, etc

I have been having some increasing issue with Finder (Won't close, etc).
For instance, Finder will not LIST VIEW files that are in the Documents folder (on the computer) Only icon or column view. It will list view items on an external drive.
I tried to reinstall the operating system (SL) but no avail. Any ideas? Thanks!

The only other thing I can think of that could cause this behavior is the DS_Store.
Let's try removing it. Launch Terminal.
Enter:
cd /
Press Return.
Next enter:
rm /.DS_Store
Press return
This should set your Finder back to default.
