We are running AutoQoS but have recently migrated our WAN service that puts our IP connectivity to a sub-interface (interface serial0/1:0.500 point-to-point and a frame-relay interface-DLCI). In our prior WAN configuration we bound the IP address directly to the interface s0/1:0.
After the migration, the auto qos statement service-policy output AutQoS is still on the interface serial 0/1:0 . Should this service-policy statement be moved down to the serial 0/1:0.500 point-to-point in order to be effective? We have been experiencing QoS problems but I understand it could be many different places, but I wanted to start here.
