WLC 5508 as anchor running 7.0.116.0 locally configured DHCP scope. Scope has been enabled. There are 2 Foreign controllers in different locations Mobility ggroups have been configured and there is communication between them I am able to ping , mping and eping. I have gone through my configuration but can't find what is missing.
Solved! Go to Solution.

Hi Keith,
It looks like we have a misconfiguration on your anchor controller configuration on the WLAN. To properly anchor a WLAN, the foreign WLC should point the anchor, and the anchor should only point to itself.
For example:
10.12.30.114 is your foreign
10.12.130.114 is your anchor
On the Foreign WLC, define an anchor pointing to 10.12.130.114
On the Anchor WLC, define the anchor pointing only to itself, 10.12.130.114 (local)
It seems we have 2 entries on your anchor, so I think the anchor is getting confused and might be trying to tunnel traffic again.

One additional note -- the WLAN config needs to match between the WLCs, we have DHCP required (under advanced tab) disabled on the foreign, but enabled on the anchor.
If we correct these 2 things I think it should work!

Hi Keith,
I would also suspect the firewall. Pings sourced from the WLC will be sent from the management address of the anchor WLC. Your wireless clients are in a different subnet, so you would want to make sure that the appropriate rules are configured on the firewall for that subnet.
You could test this if you have another device on the guest subnet inside the firewall, if so, try pinging that from a wireless client.

Hello Keith,
First, we should double check all of your WLAN settings between the Foreign and Anchor WLC. From the CLI "show wlan x" where x is the WLAN ID.
Next, we will want to capture a client debug while this devices tries to connect. We will want to capture this on both the foreign WLC and the anchor WLC:
debug client xx:xx:xx:xx:xx:xx
Where xx:xx... is the mac address of your test clients wireless interface. Please capture this output for further analysis.
Thanks,

I am pasting the debug and show wlan info below the first is for the foreign controller

Hello Keith,
From the looks of it, I think you may have accidently pasted the foreign controller output twice. Could you please confirm that you also have the anchor WLC output?

>> I assume you have the DHCP pool on the management interface!! if not please create one since ur pointing ur anchor to the management interface.
>> I have seen this issue many times on the customer network while troubleshooting!! When ever i see the logs..
*DHCP Socket Task: Sep 23 12:51:34.871: 00:21:5d:a9:2b:a4 DHCP dropping packet due to ongoing mobility handshake exchange, (siaddr 0.0.0.0, mobility state = 'apfMsMmAnchorExportRequested'
and when the configuration is correct, correct in the sense bulls eye!! then deleting the WLAN on the anchor and the foreign and then reconfiguring the same helped every single time in getting the issue resolved..
U can try the same, it may help OR may open up a TAC case or lets wait for Expert PATs reply!!
Regards
Surendra

Hi Keith,
It looks like we have a misconfiguration on your anchor controller configuration on the WLAN. To properly anchor a WLAN, the foreign WLC should point the anchor, and the anchor should only point to itself.
For example:
10.12.30.114 is your foreign
10.12.130.114 is your anchor
On the Foreign WLC, define an anchor pointing to 10.12.130.114
On the Anchor WLC, define the anchor pointing only to itself, 10.12.130.114 (local)
It seems we have 2 entries on your anchor, so I think the anchor is getting confused and might be trying to tunnel traffic again.

One additional note -- the WLAN config needs to match between the WLCs, we have DHCP required (under advanced tab) disabled on the foreign, but enabled on the anchor.
If we correct these 2 things I think it should work!

Thanks Pat , You hit it the nail right on the head. Stay tuned a couple more questions on the way. Once again thanks for your help

Ok I can get an an IP address now but I cannot get to the internet. I am thinking its the Firewall but want to make sure there is nothing I am missing. I can ping the external DNS server 8.8.8.8 from the anchor but I can't ping it from the client laptop.
09-23-2011 07:15 AM
Hi Keith,
I would also suspect the firewall. Pings sourced from the WLC will be sent from the management address of the anchor WLC. Your wireless clients are in a different subnet, so you would want to make sure that the appropriate rules are configured on the firewall for that subnet.
You could test this if you have another device on the guest subnet inside the firewall, if so, try pinging that from a wireless client.

Pat once again thanks. You confirmed my suspicion there was an incorrect nat rule on the FW when that was resolved I was able to get the authentication splash page and internet access.
