Hi Experts,
I'm practicing QOS stuffs in lab and got a question.
Here is the topology:
R1<->SW1<->SW2<->R2
there is a trunk links between SW1 gig1/0/33 & SW2 gig1/0/33, SW1 gig1/0/48
& R1 f0/0, SW2 gig 1/0/48& R2 f4/0
I'm marking all frames on R1 with COS5.
Need to see this frames as COS1 on R2. No config allowed on R2
R1
f0/0.12
encapsulation dot1q 12
ip add 1.1.12.1 255.255.255.0
service-policy output SETCOS5
R1#sh policy-map SETCOS5
Policy Map SETCOS5
Class COS
set cos 5
R1#sh class-map COS
Class Map match-all COS (id 3)
Match any
My solution is
SW1
mls qos map cos-dscp 0 8 16 24 32 37 48 56
int gig 1/0/48
mls qos trust cos
-----------------
SW2
int gig 1/0/33
mls qos trust dscp
mls qos map dscp-cos 37 to 1
#######
The config is working fine.
My question is:
Is there any other solution?
Thanks,
ZZ
