Hi All members,
Any one worked on 6500 layer 3 qos. Is there anything i need to use on
6500. I am using ethernet over mpls(eompls). i am using 6500 as PE2. i am
unable to see any matching or marking on PE2 in 6500 but i can see matching
& marking on all routers 2811 and 2821 on CE1,PE1, P and CE2.
I am using mls qos globally on PE2(6500) and on interfaces mls qost trust
cos but still unable to see any matching and marking on PE2. for PE2
configs kindly see my previous post. Any configuration more needed on 6500
qos.
PE2 CONFIG:(6503)
class-map match-all EXP_5
match mpls experimental topmost 5
class-map match-all QOS_GROUP_5
match qos-group 5
!
policy-map mpls2ip
class QOS_GROUP_5
policy-map IN_FROM_R3
class EXP_5
!
interface GigabitEthernet0/0
description to-P
mtu 1546
ip address 192.168.34.5 255.255.255.0
ip ospf network point-to-point
duplex auto
speed auto
mpls ip
mls qos trust cos
service-policy input IN_FROM_R3
!
interface GigabitEthernet0/1.50
encapsulation dot1Q 50
mls qos trust cos
xconnect 3.3.3.3 50 encapsulation mpls
service-policy output mpls2ip

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.
