Hi All,
I need your help in design one Wireless Network. We have 5520 WLC in SSO and its port are connected with two different switch. Please suggest, can we create LAG on WLC and ether channel on two different switch to have port level redundancy. IF yes,please suggest how?

connection to two different "normal"switches will not form an etherchannel
it needs to be a stack/VSS/VSL before you can configure a multichassis etherchannel.

Hi
Thanks for reply
we have two 5520 WLC and both are on different data center. both ports of each WLC are connected with core switch and DMZ switch. Core switch , is in VSS but DMZ switch is not have stack or VSS or VSL. Now, if we create SSO between both WLC and port connected with DMZ switch down, how WLC get to know, my one DMZ port down and now traffic should with standby WLC whose one port is in DMZ and working

Are the two switches in a "stack" or VSS or not?

Not in Stack or VSS. Below is more description of connectivity.

can you upload a topology, showing exactly how its connected with port details, proferably IP and vlan details as well ?

Hi Scott,
Thanks for sharing inputs.
Each DC not have own management or user Subnet . We are creating SSO over vlan by creating L2 vlan on switch port connected with RP port. Same L2 vlan create on switch which is connected with other WLC RP Port present in other DC.
Management Subnet will be same for both DC. Please suggest , how to proceed to create SSO & port level redundancy

Hi Scott,
Thanks for your inputs.
Please suggest, what is the recommended latency for RP ports.
if we create SSO between both WLC through VSS switch and port connected with DMZ switch down, how WLC get to know, my one DMZ port down and now traffic should with standby WLC whose one port is in DMZ and working.
Diagram attached

Hi Scott,
I got the answer for SSO . But as i uploaded network diagram, Port2 connected with DMZ from each DC . Now if Active WLC port2 connected with DMZ switch got down, is switchover happened?
Note: My management interface is from Port1 which is connected with VSS switch
