[c-nsp] MPLS VPN QoS not working on 6509/SUP-720

[Zahid Hassan]

Hi Capron,


Many thanks for your input.

Yes, I have spotted the mistake.


I think I have now managed to solve the problem by 
reapplying the DSCP bits under the policy map statement.

I am now seeing matches. 



!
class-map match-all VOICE
  match ip dscp ef 
class-map match-all ROUTING
  match ip dscp cs6 
class-map match-all VOICE-SIGNALLING
  match ip dscp af31 
!
!
policy-map FROM-PE-CE
  class VOICE
    priority percent 80
   set dscp ef
  class ROUTING
    bandwidth percent 9
   set dscp cs6
  class VOICE-SIGNALLING
    bandwidth percent 10
   set dscp af31
!             
PE-1#sh policy-map interface fastEthernet 3/10 output

  Service-policy output: FROM-PE-CE

      queue size 0, queue limit 20000
      packets output 0, packet drops 0
      tail/random drops 0, no buffer drops 0, other drops 0

    class-map: VOICE (match-all)
      Match: ip dscp ef 
      set dscp 46:
      Earl in slot 5 :
        0 bytes

        aggregate-forwarded 0 bytes

    class-map: ROUTING (match-all)

      set dscp 48:

        5 minute offered rate 0 bps
        aggregate-forwarded 9870 bytes

    class-map: VOICE-SIGNALLING (match-all)

      set dscp 26:
      Earl in slot 5 :
        36676 bytes

Zahid,

You may want to check your class maps.  They are configured for
"Match-all".  Match-all means you need to match every match statement in
order to be included in the class.   I would suggest using "match-any"
on the 6509 if you want to look for more than one attribute.

Dear All,


I am using a 6509/SUP-720 and a 7507 as PE routers for a customer VPN.
The CEs connected to each of the PEs are mark packets with DSCP bits.
On the PEs, I have output service policy to the CEs matching the DSCP
bits
set the CEs.
On the 7507, I am being able to match packets from the 6509/SUP-720 with
DSCP bits but
not on the 6509/SUP-720 from the 7507.

QoS is globally enabled on the 6509/SUP-720 and the CEs are certainly
marking packets.
The 6509/SUP-720 is running 12.2 SXD7.

Is there anything else that I have to enable to get QoS to work on the
6509/SUP-720 ?
I would be really greatefull for any help or input on this.
