Re: QoS over ATM on RPM-PR MGX8850

yes....it's possible configure QoS over ATM on the RPM-PR OF A mgx8850.

The config simply reply on 3 steps

1- Config class maps

2- Config policy maps

3- Applying those policy maps under the tag-switching interface

EX:

class-map match-all Voip

match ip precedence 2

class-map match-all Data

match ip precedence 1

policy-map cisco

class Voip

priority 160

class Data

bandwidth 778

random-detect

class class-default ----> Any traffic that doen't belong to any of the above

bandwidth 700

random-detect

tag-switching prefix-map 1 access-list 1 cos-map 1

tag-switching cos-map 1

class 0 available

class 1 standard

class 2 premium

interface Switch1.1 tag-switching

description *****logical conn to the LSC***

bandwidth xxxx

service-policy output cisco

access-list 1 permit any

Re: QoS over ATM on RPM-PR MGX8850

Hi ,

The problem is that the switch connections on the RPM-PR are not over MPLS these are over ATM:

!

interface Switch1

no ip address

no atm ilmi-keepalive

rpm-auto-cbclk-change

switch partition vcc 1 2

ingress-percentage-bandwidth 1 100

egress-percentage-bandwidth 1 100

vpi 0 0

vci 35 3808

!

switch autoSynch off

!

interface Switch1.1 point-to-point

description "ENLACE A RPM-PR DE MGX8830-TIJUANA"

ip address 10.103.200.165 255.255.255.252

pvc TIJ 0/500

vbr-nrt 8904 8904 1024

broadcast

oam-pvc manage

switch connection vcc 0 500 master remote

These RPM-PR are interconected across ATM subinterfaces (Switch.1.1)

MGX8830 (RPM-PR) ----------2E1 (IMA PXM1E)-----2E1 (IMA PXM1E)-----MGX8850(RPM-PR)

I am crossing ip voice traffic on these connections so I need apply QoS over these subinterfaces but over ATM instead of MLPS any idea how Can I implement this??
