  • 1.  Unable to add a new l2circuit

    Posted 10-12-2017 07:17



    I'm having a problem adding a new L2 circuit to my MX80 router.  I currently have 6 other pseudowires connected to other routers from this one, but trying to add another gives the error:


    [edit interfaces ge-1/1/2 unit 0]
    Only the CCC family is allowed on CCC interfaces
    error: configuration check-out failed


    The config for the port is:


    ge-1/1/2 {
         encapsulation ethernet-ccc;
         unit 0 {
              family ccc;

    ....which is the same format as for the other pseudowires.


    If I remove 'unit 0' and 'family ccc' from the interface then it passes the commit check ok.


    The config for the l2circuit is:


    interface ge-1/1/2.0 {
        virtual-circuit-id 1010;

    The box is running JunOS 13.3R8.7   - is there some kind of limit to the number of pseudowires that can be configured?


    Thanks for your help.

    Found the problem.  There was some legacy config of:


    set groups inline-jflow interfaces <ge-1/1/*> unit <*> family inet sampling input

    which was being inherited and causing the problem.
