Hi All,
Trying to make full use of the 9136 dual port. Enable LAG on WLC 9800-L-C for AP Profile.
However, the ports configured with LACP won't work on the switch side.
when I switch to the Normal Trunk port it works.
Does the AP not need LACP on switches to work?

After long search and help from our distributor. There a additional feature need to enable .
AP LAG mode under wireless global need to enable, which was disable by default.

In non-Dot1X ports, dual-uplink feed to a 9136 works without any LAG enabled on either side.

yes, it works well for a normal trunk port.
interface GigabitEthernet1/0/48
description Connect to AP12
switchport trunk native vlan 410
switchport trunk allowed vlan 410,100-300
switchport mode trunk
end
AP12#ping 172.16.23.1
Sending 5, 100-byte ICMP Echos to 172.16.23.1, timeout is 2 seconds

!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0.851/0.964/1.012 ms

even when i disconnect the primary connection, the WIFI is till running.
So i trying to confirm lacp is not needed no switch side.

Look for LAG with Find in your browser

what Switch model ? what IOS code running the Switch ?
can you post sample configuration of the switch side ? along with show ether x summary.
