Hi

yes, this is socket error on the control component for the radio, if you reload it would recover, but the error may happen again

the only way to prevent this, is to run a fixed code

Hi Javier,

We have opened a TAC case, because it seems we are sufering CSCvb61023 DHCP option 82. We are using an escalation version 8.1.131.34, this version fixes  CSCva95121    Stale IP route left on Flex AP config if booting up in standalone mode. do you know if version 8.2MR5 will include both fixes?

Cisco TAC told me the following:

"till now there is no clear ETA but we are pushing for the fix to be included on 8.2MR5 CCO release which should be this February"

Our end customer is a very important ISP in spain, and they are having a lot of problems with WLC bugs since they deployed EoGRE

Also TAC told me that both fixes will be included in release 8.4, this version will be avalaible at the end of February too. 

    wich version do you recommend? 

thank you very much for your help

Hi

At this time, this bug is planned to go into 8.2MR6, 8.4, and 8.3MR2

The fix arrived a bit late into 8.2MR5 program, so missed this release window.  We can include in 8.2 after MR5 is posted, please ask TAC to reach out to me

8.4 is a new feature release, so if what you need is a bug fix, it is not the best candidate, unless you also need one of the new HW or SW features included

regards

Hi,

thank you very much for your help Javier.

They don't need any new HW or SW feature, but it is very urgent to fix the issues as soon as possible.

I think the best approach is include the fixes in 8.2 MR5.

i will ask to cisco TAC. thanks

Hello Javier,

We loaded 8.2.141.10 per TAC suggestion.

We had the issue on our(WLC 5520) 2800s bug (CSCvc32706) When on 8.3.104.78.

This seemed to fix our issues, however we noticed the APs started reporting Half Duplex to the switch But showing Full in GUI, filling my switch logs with Duplex-Mismatch errors.

Shutting the port down and bringing it back up seems to correct on my 3750X sw. But on a few legacy switches won't clear the error.

Is this a bug or Caveat to the 8.2.141.10? Have you seen this before.

We have a TAC case opened, but Figured I would ask here.

Yes, ports configured to Auto-Neg. the Speed and Duplex.

TKIP support req'd.

Any input appreciated.

Hi Javier,

In the first phase of a pilot deployment of 2802/5520, 6 out of 9 APs are continually disjoining and eventually rebooting.

On checking the AP syslogs created before the reload I'm seeing a lot of these:

So it seems the AP are hitting:

CSCva74927

Barbados Flex - AP disjoins with 'Failed to get ARP entry for WLC' error

But I'm not able to view the bug because of permissions. AP's are in local mode not in Flex.

Is it likely the latest interim will resolve this issue?

Hi Bart

yes, on quick check, this seems to be CSCva74927

The fix corrects a timing issue where a discovery is sent to transmit, before the IP stack is fully up

it is corrected on the current MR build. 

if you see any issues, please let me know

Hello,

Any word on when this will be released? Feb has come and gone. I see that 8.3.111.0 is out, but no new releases for 8.2 yet.

Thanks,

Ethan

Hi Ethan

we are on final verification steps, if all goes well, it should be posted by next week

regards

Thank you

Eagerly awaiting release to see if it addresses undesirable behavior I'm seeing with 702W connected wired and wireless clients.

Hi Javier,

       We had 28 2802 series( E and I). Some of them (about 5) meet the bug CSCva98904 (2800/3800 reload: rcu_sched self-detected stall). We plan to upgrade to 8.3 MR1. We check the release note of 8.3 MR1. The bug CSCva98904 is open caveats in Release 8.3.111.0,but it had been fixed in 8.2(131.5) by your bug search notes. But  we also check the release notes of 8.2(130) and 8.2(141) ,the bug CSCva98904 had not been listed in resolved caveat list.

Does the CSCva98904 has been fixed in 8.2 MR4 or 8.2 MR5? If it is correct . Can we upgrade WLC OS to the fixed version(just to fix AP bootloader) , and then upgrade WLC to 8.3.110 ?

Sorry for my pool english.

Thanks!        

Hi Javier:

         Do I need to open TAC case to check CSCva98904 status?

Thanks!

Hi Javier,

Regarding the SNMPv3 bug (CSCvc33511) I'm still not able to manage a 5520 (latest .67 code) with SNMPv3 using Prime Infra 3.1.5 (DP7). Reload as suggested does not work either. SNMPv2c does work. Tried longer and shorter usernames and passwords and both SHA1/AES and MD5/DES. Older WLC5508 can be managed with SNMPv3 using Prime.

On debugging SNMP on the (active) WLC, I receive the following (filtered on SNMPD only):

 *SNMPTask: Mar 06 12:53:17.988: [PA] SNMPD: Packet from: <ip_prime>:63556, in_packet_len = 155

 etc...

Any idea what is happening and how to fix?
