  • 1.  VPLS DSCP

    Posted 10-11-2009 21:26

    Hi Everyone,

    Does VPLS support DSCP classification? ie.,

     

    interfaces {
        ge-0/0/0 {
            per-unit-scheduler;
            vlan-tagging;
            encapsulation flexible-ethernet-services;
            gigether-options {
                no-auto-negotiation;
            }
            unit 99 {
                encapsulation vlan-vpls;
                vlan-id 99;
                family vpls ;     

                }
            }
        }

     

     class-of-service {
        classifiers {
            dscp dscp_classifier {
                forwarding-class gold {
                    loss-priority low code-points 000000;
                }
            }

     

         forwarding-classes {
            queue 0 bronze;
            queue 1 silver;
            queue 2 gold;
            queue 3 network-control;
        }

     

        interfaces {
            ge-0/0/0 {
                unit 99 {
                    classifiers {
                        dscp dscp_classifier;
                    }
                }
            }

     

    I couldn't seem to get traffic to be classfied to forwarding class gold, but can do so for ieee802.1p

     

    Thanks,

    Wendy

    To my knowledge, DSCP classification on bridge/VPLS interfaces is supported by means of firewall filter, on MX platform only, since JUNOS 9.0:

    I'm interested to understand this a little more.

     

    Are we talking about CoS within a VPLS instance. If so this is something I've been trying to find out for while.
