  • 1.  VLAN and non-VLAN traffic on same interface?

    Posted 08-15-2022 20:01
    I want to have a single interface pass both inet 100.64.10.1/24 traffic on unit 0 and also tag a management vlan-id 99 traffic on unit 1 of 10.10.20.122/24, Is this possible single interface? I tried something like:
    ge-0/0/11 {
        unit 0 {
        description segment1;
            family inet {
                address 100.64.10.1/24;
            }
        }
        unit 1 {
        description segment1mgmt;
        vlan-id 99;
            family inet {
                address 10.10.20.122/24;
        }
    }​

    but I get an error:

      'unit 1'
        Only unit 0 is valid for this encapsulation

    Hello,

    Yes it's technically possible.
    You should enable Vlan Tagging on ge-0/0/11 before.

    ge-0/0/11 {
           vlan-tagging
    }

    I tried that, now I get the error:
      'unit 1'
         VLAN-ID must be specified on tagged ethernet interfaces

    Give this one a try.
    ge-0/0/11 {
        description test;
        vlan-tagging;
        unit 0 {
            vlan-id 0;
            family inet {
                address 100.64.10.1/24;
            }
        }
        unit 2 {
            vlan-id 99;
            family inet {
                address 10.10.20.122/24;
            }
        }
    }

    So does vlan-id 0 mean not a VLAN at all? Sort of like 0.0.0.0/0 means any?

    For the moment, I placed an unmanaged switch downstream from two ports and then connected my single connection with both VLAN and non-VLAN to that and it worked, but I'd like a more permanent solution.

    vlan-id 0 means not tag at all on that vlan.  So untagged traffic is here while the tagged traffic is handled by their respective unit configurations.
