Switching

Running 10.2 code, I've always done vlan membership as follows:

 

 

interfaces {

   ge-0/0/0 {

      unit 0 {

         family ethernet-switching {

             port-mode access;

             vlan {

                   members MOE;

}

}

}

}

vlans {

   MOE {

          description "MOE To L3";

           vlan-id 7;

           l3-interface vlan.1;

}

 

Simplistic, of course. But: working on a customer machine, I see this, and I don't know why:

 

interfaces {
    ge-0/0/0 {
        unit 0 {
            family ethernet-switching;
        }
    }

 

vlans {
    vlan200 {
        description "Vlan Description";
        vlan-id 200;
        interface {
            ge-0/0/0.0;
            ge-0/0/1.0;
            ge-0/0/2.0;
            ge-0/0/3.0;
           }
        l3-interface vlan.1;
    }

 

 

Is either correct?? The 10.4 Junos manual has conflicting examples about this so I'm really not clear on it. I know the first method works correctly. This second method I'm not so sure about.

 

Whats the difference in the two ways of assigning VLAN membership per interface??

 

TIA

They are both the same. It's personal preference. You should stay consistent just to help prevent errors, and make troubleshooting easier, but one isn't better than the other

What if both formats are used? Is the union of the two used?

 

thanks!

 

 

You can use both formats, but I believe you have to keep it at one or the other for a specific interface.
