IEEE 802.1P issue

[mmendis]

Hi every one,

I have purchased a fiber link and local ISP requested us to set Class of Service ( CoS ) value based on the precentage level Voice , Video , Business Critical & Best effot. Further they have requested us to follow the IEEE 802.1p standard.

I have configured the router interface with following configurations to set the CoS value to 5 of the data packets passing through interface.

But when I analyzed the traffic ( using Wireshark ) from the destination , I couldn't find relevant fields were confgiured. Appriciate if some one can help me to resolve this issue.

class-map match-all class-COS
 match access-group 100
!
policy-map policy_cos
 class class-COS
  set cos 5
 class class-default
  set cos 4

interface GigabitEthernet0/2.17
 encapsulation dot1Q 107
 service-policy output policy_cos
end

Extended IP access list 100
    10 permit ip any any (616731 matches)

Any help :)

Hi,

what kind of service did you order from the ISP?

Are you sure there is an L2 Ethernet path configured for 802.1Q encapsulation completely from your source router to the destination where you are capturing the packets?

And no device is is clearing the CoS field?

Best regards,

Milan
