creating double tagged packet from untagged input and vice versa

  • 1.  creating double tagged packet from untagged input and vice versa

    hi
    i am using extreme x460-24t switch.
    My aim is to feed packet (say ping) from laptop to port , say IN , and get double tagged packet out from another port (say OUT). Also double tagged packet is fed in OUT and should come out untagged from IN.
    Example -
    My laptop is connected to port 1 of switch . laptop has ip 10.0.0.2/24 . I run ping 10.0.0.1 in laptop.
    I want switch to put inner vlan tag 100 and outer vlan tag 500 on this ping packet.
    So the packet that comes out of port 5 has outer vlan tag 500 and inner vlan tag 100 .

    I am trying this setup currently (Don't know if it is the right way)
    Port 1 is set untagged for vlan 100 .
    port 2 is set tagged for vlan 100.
    port 3 is connected to port 2 via ethernet cable.(feeding one port of switch from another , is that ok ? )
    We have vman named five_hundred set for tag 500.
    port 3 is added as untagged member of this vman.
    port 4 is tagged member of this vman .
    So , I should get double tagged packets out from port 4.
    And , double tagged packets fed to port 4 should come out unatgged from port 1.

    Thanks .

    Hi,

    since 15.3.2 VMAN double-tag in a single pass is supported, with the following command:

    configure vman
