Cannot get ip address from second ssid

[eigrpy]

Hi We have WLC 5520 and several APs joined. The SSID is ABC associated with interface DEF of its controller. It can work well. Now we created second SSID ABC2, also associated with the interface DEF. and all other configuration is same as ABC. The issue is the user cannot get ip address after users connect to ABC2. Any solutions? Thank you

Do you have any AP Group configurations? if so pls check which interface map for hyour 2nd SSID under AP group configs.

Also cross-check "show wlan <wlan_id>" output for both of these SSID

Thank you Rasika for your fast reply. Yes we have ap group and already added the second ssid to the group and has the same associated interface with the first SSID., but still cannot see ip add

show wlan wlan_id command cannot work,

[Rasika Nayanajith]

"show wlan summary" should give you the WLAN_ID numbers correspond to those 2 SSID. Then replace <wlan_id> with those numbers and get the output

by comparing two outputs, there are some differences. Its helpful to this issue

You said "all other configuration is same as ABC" but that compare shows it is definitely NOT the same.

You need to check *all* config parameters on *all* tabs and sub-tabs of the WLANs to make sure they are the same.

[Rasika Nayanajith]

As you already identified there are configuration mismatches. My guest is WLAN_ID 8 is the one not working.

If this is FlexConnect local switch deployment, then I would correct that first on that SSID and the below 2 settings should fix it.

1. Enable FlexConnect Local Switching

2. Enable DHCP Address Assignment Required

i know the idea is make it exactly same. I just checked wlan to make sure all configuration is same between two except AAA, but it still cannot work. and also tried to associated with another interface/another ssid, it still cannot work. strange

[Seckerfers]

have you did a debug on your WLC? just try with one device to connect and debug with its mac.

[eigrpy]

Yes, Thank you Seckerfers.

debug ip dhcp server ... on the dhcp server(located at switch)

Please see the below. It looks like dhcp option issue. but the question is why the first ssid can work? actually the speed is very slow
