Hi All Members,
I am having problem in applying the qos in ethernet over mpls(EOMPLS). CE1(2811 router)------->PE1(2811 router)----------->P(3750 switch)--------->PE2(2811 cisco router)-------->CE2(2811 cisco router) If i am using the above senario on eompls qos. i can mark and match all cos5 and exp5 on all ce1,pe1,pe2 and ce2. all things worked fine. CE1(2811 router)------->PE1(2811 router)----------->P(3750 switch)--------->PE2(6523 or 7203 L3 switch)-------->CE2(2811 cisco router) when i am using (cisco 6523 or 6503 or 7203 l3 switch) as PE2 instead of 2811, problems started here. i didn't see any markings or matching of qos on 6503 l3 switch. Is there anything i am missing on l3 switch for qos. I will really thankful for suggestions & solutions on this issue. I have also enabled mls qos globally on l3 6503 switch as PE2. i have checked with mls qos trust cos on incoming interface on 6503 switch but nothing changes. Any more configuration needed on l3switch. why its not matching and marking. Below are the configs and output with the first scenario. ------------------------------------------------ CE1 CONFIG: class-map match-any EF match ip precedence 5 ! ! policy-map foo class EF set cos 5 !
