Port-Channel configuration with one Cisco WLC-9800 with Stack Switches

[King_1988]

Hi,

In our topology we have 2 catalyst switches as stack and a single WLC (9800-L). We need to configure port-channel between these devices. Is it possible to configure between a single WLC and two Stack switches, if it is possible please guide us how we can establish and how it will work?

Our expectation is like below :

 - It should work but consider https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-series-wireless-controllers/guide-c07-743627.html#Linkaggregationmode too.

   If you don't know how to configure port channels checkout :

  'Anyway' -> Always have a checkup of the 9800 configuration afterwards with the CLI command show tech wireless 
                     Feed the output into : https://cway.cisco.com/wireless-config-analyzer/
                                       Consider this procedure mandatory!

Hello @King_1988,

It should work.

If you have a stacked switch like a 3750 or 2960 then connect half of the ports of the WLC to one switch stack member and the other half to the next switch stack member. Switch side you have a LAG withe these physical interfaces. The WLC-side will also be configured as LAG.
