QOS can never be applied on Port Channels because they are logical interfaces. The QoS on most Cisco Devices is done at the ASIC level and so it can only be done on physical interfaces, the port channel will pass the packets to the Physical Ifs and these in turn will apply the service policy on egress.

I'm currently devising config for the device. We have a 4900M that will be connected over 2x10G to a customer. I want to apply a very simple QoS in this scenario - mark packets on input and act on that on output: class-map match-any CUST-SW-IN-PRIO match cos 5 6 class-map match-any CUST-SW-IN-AF4 match cos 4 class-map match-any CUST-SW-IN-AF1 match cos 2 3 class-map match-any CUST-SW-OUT-PRIO match qos-group 15 class-map match-any CUST-SW-OUT-AF4 match qos-group 14 class-map match-any CUST-SW-OUT-AF1 match qos-group 11 policy-map CUST-SW-IN-INPUT class CUST-SW-IN-PRIO set qos-group 15 class CUST-SW-IN-AF4 set qos-group 14 class CUST-SW-IN-AF1 set qos-group 11 class class-default policy-map CUST-SW-OUT-OUTPUT class CUST-SW-OUT-PRIO priority police rate percent 37 class class-default The idea is that there should never be more then 37% of CoS 5 and CoS 6 traffic leaving the interface. All ingress interfaces have the CUST-SW-IN-INPUT policy applied (on either physical interfaces, or PortChannels). When I try to apply the output policy I get the following: 1. On physical interface (member of the portchannel): ASAUESD01(config)#int te1/1 ASAUESD01(config-if)#service-policy output CUST-SW-OUT-OUTPUT % A service-policy with non-queuing actions should be attached to the port-channel associated with this physical port. 2. On a portchannel: ASAUESD01(config-if)#int po1 ASAUESD01(config-if)#service-policy output CUST-SW-OUT-OUTPUT % A service-policy with queuing actions can be attached in output direction only on physical ports. What am I missing here? software: Version 12.2(53)SG1 (cat4500e-IPBASEK9-M) hardware: WS-C4900M kind regards Pshem _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
