Which WLC interface should be resolved from cisco-lwapp-controller.domain
Hi,
we use several 4402 wlc and want the aps connect to connect to them via dns discovery.
It would be fine if somebody could tell me to which ip address (in our dns database) I have to add an alias for cisco-lwapp-controller.<domain>.
Is it the management interface, the ap manager interface or one/all dynamic interface(s)?
Is there any hint concerning this in the documentation?
Best Regards,
Thorsten
You use the management interface of the WLC.
Here is a good link also if you have issues:

You configuration is not correct. You can remove the line ‘domain-name CISCO-LWAPP-CONTROLLER.mydomain.com’ or replace it with ‘domain-name mydomain.com’ and configure the DNS server with both "CISCO-LWAPP-CONTROLLER.mydomain.com" and "CISCO-CAPWAP-CONTROLLER.mydomain.com" pointing to 172.16.00.25.
I suggest that you remove this line and forget about DNS and go for DHCP option 60 and 43 as you already have configured. You do not need both the DNS configuration and DHCP option 43.
Since you have configured ‘option 60 ascii "Cisco AP c1250"’ and ‘option 43 hex f104ac100019’ then your 1250s should try to associate with the controller 172.16.00.25.
Please post more of the syslog and look for events regarding DHCP option 43.
Is the address 172.16.00.25 for the WLC correct?

Hello,
I am trying to get this officeextend working.
I connected the ap and checked the H-Reap box and then officeextend and gave it a public ip. This public ip is NAT'd to the dmz controller on the firewall. (The dmz controller is 5508 running code 6.0.199.4)
I have connected this officeextend 1132 ap to a broadband connection and this gets an ip of 192.168.1.23 on its fa0 interface. all good till now.
when i console onto the officeextend 1132 AP, i get an error msg could not resolve Cisco-LWAPP-Controller.abc.uk....domain server (192.168.1.254) and Cisco-CAPWAP-Controller.home.uk...think it needs DNS set to the public ip on the local asdl box, is it ?
if this is the case, I am not sure if i can do this as this is controlled by the ISPI have added this now scott on the management interface but still cant get the AP to join the controller. This AP is connected to a broadband wireless router connected back to a ADSL router that has the DNS settings
(also i cant see any traffic hitting on ports 5246 and 5247 on the firewall. so think this AP is not trying to go out )
it comes up with
CAPWAP-5-DHCP_RENEW: Could not discover WLC using DHCP IP. Renewing DHCP IP.

LWAPP cannot translate cisco-lwapp-controller
Hi all:
I had add a hostname to DNS server as CISCO-LWAPP-CONTROLLER . and i use my controller as a internal DHCP server , it will assign ip to a lot of vlan. My lightweigh ap cannot translate the cisco-lwapp-controller and other a record at DNS server .Can you translate that on the local lan? Verify that the manamgement and ap-manager is configured for vlan "0" untagged and that the trunk port is setup with the native vlan of the WLC management and ap-manager interface. If you console in the ap and power cycle the ap, what does the log show. Post the log so we can take a look at it.

Which swype app should I download from the Market?
I know this isn't a huge deal, but I just want the best swype app that comes standard with the other android phones...from your experiece which is the best to download from the app market?
go to swype's website. they have an open beta version right now and i loaded it on my inc and it worked great. it's not an official app in the market. you have to get it from swype themselves. you register and they email you instructions. it's real easy to download and install though.

Which audio interface should I pick?
So I recently purchased a brand new MBP, and am pleased to discover that my Tascam US-122 that I have been working with for the past 8 years (and four computers) has finally stopped being compatible with my computer. That, then, gives me the task of purchasing a new interface.
The last major recording project I did, I tracked drums on a Presonus Firestudio Tube, and I loved it. I'm willing to make the investment in a heftier interface, with more audio inputs and (obviously) a higher price tag, but I am caught in the question of whether to get a FireWire or USB interface. I have heard different upsides and downsides about the two of them. Personally, at this point, I am more inclined to go with a FireWire interface, as it leaves me with both of my USB ports (which I use for a mouse and midi controller while recording), and I have never had latency issues with FireWire (even on a 4-year old MacBook).
So now, I am asking for input. I am not brand-specific or anything like that. I just want one that works, sounds good, and won't give me trouble.There is no way to answer your question. You need to look at what you will be running and then select the computer that will be the best for those applications.

On which interface should i open ports?
Hi!
Got a case from a customer. They want me to open some ports so that one client can use some applications.
The problem is, I am not sure on which interface i should open the ports. The customer have about 10 interfaces on the ASA. It's a client on the inside network and it should be able to talk to internet through the ports, and anyone on the internet should be able to reach the client on the same ports.
The client uses a static IP.
Sent from Cisco Technical Support iPad AppHi,
You need to map the flow of traffic for your customer. That way you can plan the changes without breaking anything.
It could be as simple as creating ACL's for the inside and outside interfaces + nat or something more complex. -
Cisco 3702i running on a WLC 8500 Drawing low power from 2960s
Hi ..
I keep getting alarm errors in Prime 2.1.
"Access point 'AP01' associated with controller 'WLC-01'
draws low power from Ethernet. Failure reason: 'The AP draws 15.4
watts from Ethernet'.
Prime is running version 2.1
WC is a 8500 running software version 7.6.120.0
2960s is a WS-C2960S-48FPD-L running Version 12.2(55r)SE
I have all ready done the following & still getting the same results :
1)Used the port command "power inline port maximum 30000
2)check & unchecked the box marked pre-standard power
3)Enabled CDP on the AP and PoE+ Switch
4)check & unchecked "Pre-Standard State" and "Power Injector State"
Any help with this would be most appreciated .
Regards
ChrisCould be similar to the below bug, Please the TAC notes at the bottom
AP process CDP packet addressed to bogus multicast address
CSCtc39367
Description
Symptom:
All AP1252s in a given VLAN, which are on switchports configured for extended
PoE (16.8 or 20W), may intermittently see their power draw simultaneously
drop to 15.4W.
At the same time, the APs will each log a message similar to the following:
%CDP_PD-2-POWER_LOW: - INJECTOR_DETECTED_MULTIPLE_MACS_ON_HUB
AIR-LAP1252AG-A-K9 (001e.bead.7c5f)
Conditions:
Another AP in the AP1252's broadcast domain intermittently transmits
a CDP packet to a bogus multicast address (i.e. one other than
0100.0ccc.cccc), such as fdc8.a414.cccc.
Workaround:
On all of the access-ports to which the APs are connected, configure
a mac access-group that filters out non-IPv4 multicasts that are not
addressed to valid multicast MAC addresses.
For example:
Cab4-Cat4507Rc(config)#mac access-list extended WOOF
Cab4-Cat4507Rc(config-ext-macl)#deny any any
Cab4-Cat4507Rc(config-ext-macl)#int gig1/2
Cab4-Cat4507Rc(config-if)#mac access-group WOOF out
(this blocks all non-IPv4 traffic that is not sourced by the switch.)
Further information: So far two TAC cases have been reported to Cisco matching
this bug. In both cases only one Access Point was transmitting these CDP
packets causing all other Access Points to drop the power consumption. In both
cases an RMA was done for the faulty Access Points.
If you require any help in isolating whether you are facing this bug on your
deployment please open a TAC Service Request. -
I need to setup 7800 Series IP Phones in the CUCM 8.6.2 which by default are not support but will work after install the software. Anyone have document from Cisco as I remember I seen once before.
Hi Ali,
I'll just add this reference to the good tips from my friend Manish (+5)
Support for the 7800 series in CUCM 8.6.2 was first added with this
Device Pack;
Cisco Unified Communications Manager
Device Package 8.6(2)(24104-1)Release Notes
Cisco Unified Communications Manager Device Package Release 8.6(2)
adds support for the Cisco IP Phones
7821, 7841, and 7861 running SIP firmware release 10.1(1).
The steps are in this doc
http://www.cisco.com/web/software/282074299/107528/cmterm-devicepack-8.6.2.24104-1_Readme.pdf
You might as well install the latest 8.6.2 Device pack
cmterm-devicepack8.6.2.24112-1.cop.sgn
Cheers!

Automatic MAC account creatation from Cisco WLC
We are creating a BYOD network, have any of you tried this?
1) First time user attempts to connect to byod_ssid they are presented with captive portal page that requests AD credentials. In the back ground users MAC address needs to be captured.
2) All subsequent connections to byod_ssid are MAC authenticated.
I am not finding any documentation on this process from the Cisco side. What do you think? Is it possible?
