I have a hub and spoke enviroment using all cisco 2811 routers.
I am currently working on qos.
I have apply class -maps and policy-map on one router close to the source as per best practice.
I went to second router and configure qos, i tried to use class-map match dscp21 etc ---- since i do not want to remark packets
previously marked at the source.
The problem is that when i check the second router using the sh policy-map int I am only see all the packets being queued under class-default
which suggest that the match dscp21 etc is not working.
Is there a something missing do i have to issue some command etc to allow the other sister routers to trust the orginal marking.
Attached are two file for clarification
Yup, exactly what Jon posted.
Geez Jon the notification email and your response came in at the same time. You're now faster than email.
1) You need to enable QOS globally on the switch ie.
2960(config)# mls qos
2) the "mls qos trust dscp" command is an interface command not a global config command so if you need to apply it at the interface level eg.
2960(config)# int gi0/1
2960(config-if)# mls qos trust dscp
