Can't Commit QnQ Protocol Tunneling

  • 1.  Can't Commit QnQ Protocol Tunneling

    layer2-control {
        mac-rewrite {
            interface ge-0/0/0 {

    Trying to commit that on a 2300c on 21.4R3-S2.4 or later, results in:

    # commit check
    error: Check-out failed for Layer 2 Control Protocol process (/usr/sbin/l2cpd) without details
    error: configuration check-out failed

    Logs only showing - "l2cpd[13838]: L2CPD: read configuration-db failed". I've only seen one similar post on reddit. Juniper rep has never seen any errors like that, either.
