Hello, Cisco Support Comunnity
I have a problem that hopefully you've got and you can help me
We have a WLC 4402 in our network, we have 12 AP's and we have three SSID's that are assigning IP addresses from three different DHCP pools configured in the core router, the situation is that we want one of the SSID's not to assign the IP addresses from the core router, in order to do this we configured a new VLAN and DHCP pool in a layer 3 switch in other segment, when i assign the SSID to the new VLAN with the IP address it can't conmunicate with the VLAN, i mean the SSID that is assign to the new VLAN can't talk with the WLC.
are you able to ping L3 switch from wlc ? and also plz check whether that particular vlan is allowed on the trunk port of the WLC or not.
