Connectivity to WLC failed

[Milton Tizoc]

We have a WLC connected to a 6500 Switch, when tried to enable LAG the connectivity goes down, the switch can't ping the controller nor the controller to the switch, we check tha cables, the minigybics, we changed them for new ones,the status of the interfaces is UP UP, we tried revert the config, using LAG disabled and no success, i can't reach the management interface. with the service port i can connect to the controller.

Thanks, Regards

Make sure you have the management and ap-manager interface set to "0" untagged and also make sure the trunk ports are set to native vlan . Also make sure that the trunk port is set to channel-group X mode on.

Thank you very much, in fact the problem was i had the management and ap-manager interface set to a specific vlan, when i changed them to "0" all was fine.
