HELP! do QoS on cisco 2811 router

Our company uses N7K as our core switch, and all subcompany link to this N7K through MPLS-VPN. But VPN bandwidth is not enough for video meeting, QA etc, so we need to do QoS, the devices of our subcompanies are cisco 2811 routers, and configuration like:



policy-map QOS-OUT

class CLASS-VOIP

priority 1500

set dscp ef

class CLASS-OA

bandwidth 1000

random-detect dscp-based

set dscp af31

shape average 1000000

class class-default

fair-queue

random-detect dscp-based

shape average 1000000



It’s too hard to do this similar configuration for N7K, there is no configuration file can be found and office configuration files are not compete. I tried many times and the result is priority and bandwidth can’t be realized at the same time on one policy-map. Here is configuration about QoS on N7K.

policy-map type queuing QOS-OUT

class type queuing 1p3q4t-out-pq1

priority level 1 // Whether all of the bandwidth will be taken up when the bandwidth can’t be used and the bandwidth limitation can’t be realized.

class type queuing 1p3q4t-out-q3

bandwidth remaining percent 20 //can’t run bandwidth command, or debug assertion failed

queue-limit 10 mbytes

random-detect cos-based // here is there any problem of queue-limit?

class type queuing 1p3q4t-out-q-default

bandwidth remaining percent 10

queue-limit 20 mbytes

random-detect cos-based



Plus：

when user-defined class-map type queuing match-any my-1p2q4t-out-pq1, match just supports to be followed by class-map and cos, not dscp, and the class-map with any following setup class-maps would be reported error.
