    Alok, are you talking about simply adding a vlan to a port?

    Yes Eric, We want to create sub-interfaces on a single Ethernet port.

    First, create the new vlan "create vlan v10 tag 10"
    Then add it as a tagged interface to an existing port "conf vlan v10 add port 5 tagged"
    Once you define an object in EXOS (like v10), you can even leave off the qualifier and make it simply "conf v10 add port 5 tagged". Repeat the two lines for each subinterface you wish to add to the port.

    I should add, some older (I think) versions don't allow the tag addition when creating the new vlan. Those are done with two entries:
    create vlan "V11-LegacyLan1"

    configure vlan V11-LegacyLan1 tag 11

    Then add the port to the vlan as tagged: conf v11-LegacyLan add port 5 tagged
