[c-nsp] EoMPLS QoS

Wed Feb 15 09:10:48 EST 2006

Hello,

Has any body deployed QoS for EoMPLS ERS on Cisoc 76xx series 

I am trying to do so but facing problem.

Any help would be appreciated :-)

Also I would request you to help me with Egress Policy to convert EXP bits
back into CoS bits to be handed over to customer.

In this requirement, the customer will be terminated on the PE itself, there
is no involvement of U-PE. The CE will be sending us traffic with different
CoS bit which we need to honor and convert into appropriate Class of Service
in our Core end to end.

For this we want to know:

1)       Appropriate configuration required on PE - 76xx

2)       Appropriate configured required on PE - 7206 VXR

Actual Setup Required 

================

CE1 ---- PE1 ----- MPLS N/W ----- PE2 --- CE2

PE1 = Cisco 7606 with WS-6724 Gigabit Ethernet module as customer facing
line card

PE2 = Cisco 76xx with WS-X6748-GE-TX      48 Port Gig Ethernet module

Current Test Setup 

==============

CE1 ---- PE1 ----- MPLS N/W ----- PE2 --- CE2

PE1 = Cisco 7606 with WS-6724 Gigabit Ethernet module as customer facing
line card

PE2 = Cisco 7206 with Gigabit Ethernet Module

ERS would be setup between two PE , on PE1 I shall be using SVI to setup a
VC whereas on Cisco 7206 I shall be using dot1q sub-if .

Below is the QoS config I have configured.

class-map match-any BestEffort-EoMPLS 

match cos 0 7

class-map match-any Business-EoMPLS

match cos 1 2

class-map match-any Multimedia-EoMPLS

match cos 3 4

class-map match-any Realtime-EoMPLS

match cos 5

!

policy-map EoMPLS

class Realtime-EoMPLS

police cir 128000 bc 8000 be 8000 conform-action set-mpls-exp-transmit 5
exceed-action drop

class Multimedia-EoMPLS

police cir 128000 bc 8000 be 8000 conform-action set-mpls-exp-transmit 4
exceed-action drop

class Business-EoMPLS

police cir 128000 bc 8000 be 8000 conform-action set-mpls-exp-transmit 2
exceed-action drop

class BestEffort-EoMPLS

police cir 128000 bc 8000 be 8000 conform-action set-mpls-exp-transmit 0
exceed-action drop

The policy map has been applied in input direction on PE1 and PE 2 below is
the config for the same

PE 1

interface Vlan300

 no ip address

 load-interval 30

 xconnect 192.168.196.6 300 encapsulation mpls

 service-policy input EoMPLS

end

PE 2

interface GigabitEthernet0/2.300

 encapsulation dot1Q 300

 no ip directed-broadcast

 no cdp enable

 xconnect 192.168.196.37 300 encapsulation mpls

 service-policy input EoMPLS

end

Problem Statement

=============

On the 7606 PE ( PE1 ) , I am not able to see any traffic being matched in
any of the class , not even in default class (considering that CoS setting
from the CE can have problems) . Also on the PE 1 the "show policy-map
interface vlan 300" command doesn't displays that mpls exp bit imposition
configuration value though it has been configured on the CLI.

#sh policy-map interface vlan 300

 Vlan300 

  Service-policy input: EoMPLS

    class-map: Realtime-EoMPLS (match-any)

      Match: cos  5 

      police :

        128000 bps 8000 limit 8000 extended limit

    class-map: Multimedia-EoMPLS (match-any)

      Match: cos  3  4 

      police :

        128000 bps 8000 limit 8000 extended limit

    class-map: Business-EoMPLS (match-any)

      Match: cos  1  2 

      police :

        128000 bps 8000 limit 8000 extended limit

    class-map: BestEffort-EoMPLS (match-any)

      Match: cos  0  7 

      police :

    Class-map: class-default (match-any)

      0 packets, 0 bytes

      30 second offered rate 0 bps, drop rate 0 bps

      Match: any

In contrast to this , on 7206 VXR I am able to see the proper output for
"show policy-map interface g0/2.300"

#sh policy-map interface g0/2.300
