    hello Max

     

    So what this means is that the l2ald which is the l2 learning daemon is not running, are you running the command from the master? you should see master, backup or linecard in your terminal like this 

    {master:1}[edit]
root@SWITCH#

     

    is the VC actually truly formed? 

    >show virtual-chassis status

    perhaps it is in linecard mode and it doesnt run the l2 learning daemon?

    if you are in the master and l2ald is not running there is something wrong the process should start with the device check that out first.
