Mobile device reassociation

ahcadmin1 — Mon, 05 Jul 2021 10:50:25 GMT

Hello,

We have recently added an SSID for employees to access the internet. Everything seems to be working fine, except that mobile devices will sporadically lose internet connection with the message: "DNSProbe finished no internet". Eventually, it will reconnect on it's own, but a manual disconnect and reconnect to the SSID temporarily resolves the issue faster. I have noticed that each time this happens, the devices renew their DHCP lease w/ the same IP address. I ran a debug on my mobile client and see that this occurs every time there is a loss of connectivity:

Also worth noting that this happens without roaming, just sitting at my desk. Any help is greatly appreciated.

Hi,Can you provide more info:

Hi,

Can you provide more info: Paste the output of these commands from WLC.

1. sh wlan <wlan_id>

2. Sh sysinfo

I would rather not. I can

I would rather not. I can provide any info you need specifically though.

Standardize WLC debug messages across release

CSCut93840

Description

Symptom:
Debug logs from WLC look in different format in different releases

Conditions:
Prior to 7.6 release, on WLC debug client output looked like:

*apfReceiveTask: Oct 15 15:48:07.597: 3c:a9:f4:01:21:84 pemApfDeleteMobileStation2: APF_MS_PEM_WAIT_L2_AUTH_COMPLETE = 0.

After 8.0:
*apfMsConnTask_3: Jan 28 10:38:53.305: [PA] 00:0e:8e:50:86:87 Applying Interface policy on Mobile, role Local. Ms NAC State 2 Quarantine Vlan 0 Access Vlan 523
*apfMsConnTask_3: Jan 28 10:38:53.305: [PA] 00:0e:8e:50:86:87 Re-applying interface policy for client

We started adding works [PA] into debugs which is of no useful info. But affects debug parsers like https://scripts.cisco.com/ui/use/WirelessDebugClientGold

Need to make sure that we have a standard version for future parsing needs and not keep editing the way debug looks.
