[j-nsp] QFX tag stacking help please

[Kody Vicknair]

Eric,

I hope this helps - This is working on an ACX5048 chassis today, should be the same as the qfx:

description "ZZZZZZZZZZZZZZZZZZZZZZZZZZZZ";
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 774 {
    description "YYYYYYYYYYYYYYYYYYYY";
    encapsulation vlan-vpls;
    vlan-id-list [ 2774 3774 ];
    input-vlan-map {
        push;
        vlan-id 774;
    }
    output-vlan-map pop;
    filter {
        input police-100M;
        output police-100M;
    }
}
unit 990 {
    description "XXXXXXXXXXXXXXXXX";
    encapsulation vlan-vpls;
    vlan-id 990;
    family vpls;
}

I have a 5110 18.1R3-S6.1 facing a trunk with a vlan coming with stacked.



Xe-0/0/46 comes in on 1079 with inner 776, 777.



I'm having a heck of a time figuring out the proper mapping to make this work. Different docs don't seem to line up with available commands so I've been getting nowhere on this.



I was assuming that input-vlan-map needs to pop and output-map-map needs to push the 1079, but how do I specify 776, 777 to that sub?





flexible-vlan-tagging;

mtu 9216;

encapsulation extended-vlan-bridge;

unit 1079 {

    vlan-id 1079;

    input-vlan-map pop;

    output-vlan-map push;

}



I've got a local named vlan for 776, and 776 coming into the switch from other sources (the easy part).  Where do I specify those vlans to hit the port to the SP?



There will be other vlans with different inners on that port.  So for examples sake something like:



unit 1079 {

    vlan-id 1079;

    input-vlan-map pop;

    output-vlan-map push;

}

unit 1080 {

    vlan-id 1080;

    input-vlan-map pop;

    output-vlan-map push;

}



Where 1079 has 776, 777 and 1080 may have 500-510.  Doesn't really matter what they are as long as I can map at this stage.



Thanks in advance,

Eric
