Hi everyone,
I am working on 5508 cisco WLC, and I can not access WLC with SSH or GUI when I enable LAG,
when LAG is disabled, the GUI and SSH access works fine.
I am running the software version : 8.5.120.0.
thanks in advance

Hi,
find below the configuration on the switch side :
interface Port-channel2
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast trunk
end
SW#
SW#sh run int Gi1/0/10
Building configuration...
Current configuration : 126 bytes
!
interface GigabitEthernet1/0/10
description vers_WLC
switchport trunk encapsulation dot1q
switchport mode trunk
end
SW#sh run int Gi1/0/12
Building configuration...
Current configuration : 161 bytes

Configure them as indicated below:
The controller’s neighbor devices must also be properly configured to support LAG.
Each neighbor port to which the controller is connected should be configured as follows:
interface GigabitEthernet <interface id> switchport channel-group <id> mode on no shutdown
The port channel on the neighbor switch should be configured as follows:
interface port-channel <id> switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan <allowed vlans> switchport mode trunk no shutdown
