Cisco QOS on WLC ports connecting to switch

[zahir_ahmed]

Hi,

Can someone please explain whether i need "auto qos trust dscp" or auto qos trust cos" command on the ports that are connected to the switch. The WLC is configured to use LAG when connecting to the Cisco 6500 switch. The switchports are configured as a port-channel on the Cisco switch.

I am using autoqos across the wireless and wired network.

Thanks

Zee

Hello,

You better do a trust cos on the port where  controller is connected since it's L2 trunk.

Cheers,

Brendon

Zahir,

WLC --> SWITCH = COS

AP --> SWITCH = DSCP
