Hi ,
We have a WLC management IP Address configured as 10.40.124.59.
and configured VLAN1 on WLC with IP address 10.40.126.250.
we are unable to ping the VLAN1 ip address from the switch. even unable to ping 10.40.126.252 (Gateway). Is there any limitation that we can not configured ip address from secondary scope...
Switch vlan 1 configuration is ......
interface GigabitEthernet0/0.1
description Business VLAN
encapsulation dot1Q 1 native
ip address 100.93.50.2 255.255.0.0 secondary
ip address 10.40.126.252 255.255.255.0 secondary
ip address 10.40.124.61 255.255.255.192 secondary
ip address 100.43.94.252 255.255.255.0

Thanks

I've never seen it in a document, at least not a public facing document.....
That being said, the WLC doesn't 'bridge', it requires an IP on the interface so that it knows when it needs to L3 vs L2 roam a client. When you run secondary addresses on the VLAN interface on the LAN, the WLC has no knowledge of the extended IP scheme.
Any other device, that just relies on a VLAN tag, works fine.

The WLC does not play well with secondary addresses.
