Does the autonomous 1242AG forward broadcast packets?

I have an autonomous Cisco 1242AG AP connected to L2 switches.
Let's say I have 100 wired devices each sending 2 broadcast UDP packets per second.
Obviously these packets will reach the Access Point switch port, but will the AP actually send these packets (200 pps) into the air?
Thanks

Here is the configuration guide for the WLC 4402 and 1130AG follow the configuration guide which will help you

Does the inability to forward mail from the new In...

(1) Am I right in believing that simply by opening an email you can pick up a trojan or other nasty? That's what I've always heard.
(2) Am I also right in saying that we can no longer 'forward' an email when viewing the list of 50 emails in the Inbox?
(3) If I correct on both counts, if I receive what clearly is a dodgy email and I need to forward it to a Third Party such as Paypal, I can't. To access the Fowrad button, we need to open the blasted email = puts us at risk.

ah - STZ1300man - you may have uncovered yet another dastardly attack on we poor XP/IE8 users.
Microsoft tried to kill us off once and failed but so many sites are now demanding IE9 or later so that we may "experience the full delights of everything we are offering"! Gmail, FileHippo and others, and now BT forum.
I'll try later on my Win7/IE9 laptop - I bet that's OK!

Does the browser back/forward literally not work?

Does anyone else find the Browser/Media tab so frikkin annoying?
I'm browsing through folders to find samples to put into my project and everytime i go back, it goes back to the last folder full of samples i was in, rather than literally going 'back.'
It literally doesnt work!
I also find that we need favourites like Ableton does.
And... the right click on the home icon and selecting 'set current folder as home' only works whilst you have that session open. When you close and reopen its forgotten!
Bah Humbug APPLE!

Spry or regular hyperlinks in a list or nav configuration. Either is better than Flash buttons.
Thing is, a search bot will read the HTML in those kinds of links (spry or HTML) and index them. That way if you have an event calendar for upcoming shows, or a discography page, it can find them and will be able to make a reference to them in later search engine databases (usually about 72 hours after the indexing). With the Flash buttons there is no code for the bot to find and your upcoming events, or a downloads page if there is one, will never be seen in a search even if people look directly for "fireonmcginnis: schedule", or "music by fireonmcginnis" because to Google, Yahoo, Lycos and the others the pages simply don't exist.
Spry is great if you have submenus, and since it can be customized using CSS, you can make it match your site layout. You can also do that with regualr hyperlinks and CSS, but spry has a more appealing look to a lot of web users and the submenus are a little harder with basic HTML.
For the record the script should read: getURL ("http://www.site.com/page.html" "_self"); for the buttons. There'a s drop down to select _self, _blank, _parent etc. when you add the getURL script to the button.
But... you need to stay away from Flash buttons for navigation or you're really defeating the purpose of putting a band on a website in the first place. It's about exposure and Flash buttons will severely limit that exposure, even if they work properly.

Does the latest Time Capsule broadcast 802.11n better than original?

I'm in a 1700 sq ft house with my original 500 GB Time Capsule upstairs and a MacBook Pro unibody downstairs in the living room. With 802.11n only or 802.11n/g/b enabled on the TC, the MacBook Pro can't detect a network.
Would a new Time Capsule broadcast the 802.11n significantly better than the original in this situation?

Bob Timmons wrote:
The newer version of the Time Capsule has an "improved" antenna design that may help things a bit. But, if you have no signal now, I very much doubt that a new Time Capsule would provide you with a usable signal in your situation, given the information in your post.
Have you verified that the MacBook Pro is working correctly? Can you get a good signal when it is close to the Time Capsule?
Yes.
If things check out when the MacBook is close to the Time Capsule, then this would indicate that you have too many obstructions...walls, ceilings, etc. between the Time Capsule and the MacBook when it is downstairs.
Yes, if I set the TC to 802.11n/b/g or 802.11n only, the MacBook Pro won't see the network. If I set the TC to 802.11g only, it shows full signal strength. This isn't surprising to me, as I have an older Airport Express whose signal also could be easily picked up downstairs.
Is there such a difference in range between 802.11n and 802.11g?
You may want to consider an AirPort Express to position it at an approximate mid-point between the Time Capsule and downstairs so that it can "extend" the wireless signal downstairs.
To get an idea if this might work, move your MacBook to a position that is 1/2 to 2/3 of the distance from the Time Capsule to the downstairs area where you want to use the MacBook. If you can get a good signal on the MacBook at that point, this means that an AirPort Express should receive a good signal as well so that it can "extend" the wireless network.
It's never possible to predict performance in advance, so if you want to try the AirPort Express, it would be a good idea to know the store's return policy in case things don't work as well as hoped.
Thanks.

The FTP protocol: How does the AE manage inbound packets?

I've noticed the following with resect to how the AE handles NAT port forwarding for the FTP protocol.
1. Forwarding for FTP service seems to only work if the WAN port is 21, e.g. map 21 -> 21 works, 2121 -> 21, does not work (packets seem to be dropped at the AE). However, such a restriction hold with other services such like ssh or openvpn.
2. When ftp packets are received by the LAN server, they have the IP of the client stripped and arrive at the server with the WAN IP assigned to the AE, as indicated by the logs. Again, other services that we are forwarding to the server arrive with the correct client IP. So this is only an FTP thing.
The AE seems to do some analysis of incoming packets and treat them differently. One question:
Why does the Airport Extreme do this, and apparently only for FTP packets?

I found a workaround by changing the port my FTP server listens to from 21 to 2121. I then set the AE to forward port 21 on the WAN side to 2121 on the LAN side. This allows the server to know what IP the client is connecting from.
I'm still curious why the AE strips the client's IP when you forward to port 21 on the LAN side.

Whenever system does the forward scheduling for the external procurement ,

Dear Guru,
In one of plant i have a typical problem.
Whenever system does the forward scheduling for the external procurement , system does not takes Todays date (MRP Run date).
System simply sifted the requirement date by 30 days. and scheduled accordingly. In the expection message system shows the correct requirement date.
Please help.
Regards,
Sanjay

Dear ,
Can you let us know what value you're using for Scheduling when you carry out MRP run 1 or 2 ? Are you getting Planned Order while running MRP ? Wht is the Lot Size are you using in the MMR-MM02-MRP1 view ? Wht is GR processing Time and PDT?
Check the following in your case :
1.Go to Transaction code omi4- Select the MRP lot sizeGo to the "Scheduling" in the Tab Lot size for the short term period-
Check the Scheduling indicator : Requirement Date =Delivery Date in MRP Lot sizing Procedure in OM14.Basically ,this indicator defines the time in the period the system is to create the availability date or the start date for the lot for period lot-sizing procedures.
2.Goto OPPQ-Carry All Overall plant parameters -Order Start date in the Past -Check wether you are marked.
3.Goto -OMEW-Check the PR processing time in days

Unable to receive UDP broadcast packets on PPP connection

I am struggling for two days now with no success. I have two modems (do not ask, some special stuff), that uses dial up (PPP) connection. I tried this on windows XP and it works like a charm. I am sending unicast and broadcast UPD packets. If I
repeat that on Windows 7 i can send only unicast data, broadcast packets seems to be lost somewhere. I tried to use Microsoft Network Monitor and I can see that broadcasted packets are being received on my PPP connection. But after that, they are gone. Somewhere
in the kernel. I truly do not understand why. I disabled firewall, antivirus, base filtering engine, tried to log dropped packed in Windows
Filtering Platform, tried clean WIN7 machine and all that with no success.

Hi,
From your description, you may gather the network monitor traces to ensure which part lost UDP broadcast packets.
Thank you.

Does the apple thunderbolt to ethernet dongle support promiscuous mode ?

Does the apple thunderbolt to ethernet dongle support promiscuous mode ?
I need to use the new Retina MBP as a professional laptop for work, and I need to use Etherreal. Etherreal needs the Ethernet card/dongle/chip to run in Promiscuous mode. I have heard that unblivably the thunderbolt Ethernet dongle does not support this, if so then the laptop will not pick all the packets on the wire... is this true ?
Regs Mark.

Hi Clinton,
Thanks for your reply, However the promiscuous mode function that I am after is a function of the Ethernet NIC hardware and driver not just the OS.
Wireshark allows the user to put network interface controllers that support promiscuous mode into that mode, in order to see all traffic visible on that interface, not just traffic addressed to one of the interface's configured addresses and broadcast/multicast traffic.
Anyone out there actually used/tested the thunderbolt Ethernet adapter to sniff traffic with wireshark (Ethereal), can you please if it can run in promiscuous mode ?
Thanks.

Hi
I think we have experienced something similar and we did a 'more' on the env_vars file and found that the env_vars contained out of date IP default gateway information.
For example:
We established that the env_vars file contents have not been updating correctly. Documentation on the Cisco site suggests that changes to IP configuration information should be reflected in env_vars after a reload of the WAP.
This does not always seem to happen.
As an example, this env_vars contains the incorrect information that the static IP is XX.11.60.100, which is incorrect and at least least a year out of date, despite having undergone reloads since being reconfigured. Obviously, if the WAP comes up using this info, the gateway address etc. will not work...and the WAP is unable to contact the WiSM. We have also had a case where the incorrect DNS address is stored and used, which might be more of an issue for you looking at your output above.
WAPXXX#more flash:/env_vars
DEFAULT_ROUTER=10.0.0.1
ENABLE_BREAK=no
IOS_DEFAULT_DOMAIN_NAME=XXXXXXXXX
IOS_NAME_SERVER_ADDR=XX.11.159.122
IOS_STATIC_DEFAULT_GATEWAY=10.11.63.250
IOS_STATIC_IP_ADDR=XX.11.60.100
IOS_STATIC_NETMASK=255.255.252.0
IP_ADDR=10.0.0.1
MANUAL_BOOT=no
NETMASK=255.255.255.224
TERMLINES=0
We wrote a script to go around and delete all the env_vars files on the 1240 WAP but then discovered that the LWAPP migration tool forces a reload of the WAP that auto-generates the env_vars file that we just deleted, complete with the wrong information again!
I can offer no solution on how to stop the old information being written to env_vars, as I cannot find where it is stored in the first place, it must be somewhere in the flash, but am aware that other people in UK educational establishments have also experienced this issue without a proper fix being provided.
The usual solution appears to be to get the WAP on your desk, delete the env_vars file and then pull the plug on the power. DO NOT SAVE/RELOAD. Put the power lead back in and the WAP should come up without refering to the env_vars file and will take all and any DHCP info you are providing.

How does centrally-switched wireless handle broadcasts?

I'm not sure about how broadcasts are handled in a centrally-switched (not FlexConnect) environment. Our network has large /22 networks for wireless users...in a traditional wired world, that's a big broadcast domain. Add multiple /22 networks in an interface group and it's even bigger. Is this a concern? Will wireless clients really process broadcasts from these networks as wired clients would?

The WLC does not forward broadcast unless you have broadcast forwarding enabled on the WLC.
http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/secwlandg20/sw2dg/ch4_2_SPMb.html#wp1307340
The WLC by default does not forward broadcast messages from WLAN clients back out onto the WLAN, which prevents a WLAN client from acting as a DHCP server and spoofing incorrect DHCP information.

So this "Rejecting update: Lease..." is not a error message, right?

For encrypted flows, how does the MPLS do the QOS?

After encrypting the data, send them to MPLS, how does the MPLS do the QOS?

Hi,
the IPSec standard mandates, that the ToS Byte from the original header is copied to the new IPSec header. So if your IP packets are already marked everything is straight forward - MPLS does not make any difference. For the MPLS network it will be just marked IP packets and the marking is copied to the MPLS experimental bits. QoS policies within an MPLS core only use experimental bits only.

WLC(s): are "forwarding" broadcast pkts when I don't want them to.

The symptom is whenever a wireless clients generates a broadcast packet the WLCs pick it up and send it(capwap encapsulated) to each and every AP(Unicast) in every building. Such that a single client broadcast packet causes our WLCs to generate 1000 separate packets.
We have multiple buildings(20) connected by VPN's over cable modems. Each building has ~25+ APs all set to Flex-Connect and local switching. Back here at central we have several 5508 WLCs.
We have broadcast forwarding disabled.
Show Network Summary
Ethernet Multicast Forwarding............... Enable
Ethernet Broadcast Forwarding............... Disable
IPv4 AP Multicast/Broadcast Mode............ Unicast
IPv6 AP Multicast/Broadcast Mode............ Unicast
IGMP snooping............................... Enabled
I'm calling these CAPWAP encapsulated packets "broadcasting forwarding" but I not sure that is the correct way to describe them. Either way I'd like to understand what the packet are and can we make them stop.
The TOD(Theory Of the Day w/all due respect to Stephen H.) is that these unicasts to the APs are somehow related to Layer 3 mobility....

What is the WLC software version in this case ?
Refer this link & that explain WLC default behavior for wireless client's broadcast packets. It should not broadcast to other wireless clients/AP.
http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/emob73dg/emob73/ch2_Arch.html#pgfId-1058225
In your case, if you can take a wireshark capture of the AP connected switchport you can verify client broadcast is forwarding as it is or not. It is good if you can take OTA capture as well so you can confirm client sending broadcast traffic.
