    Hi guys,

     

    I have an EX4200-48T VC with 4 members. The vme.0 is already configured and working. Now I need another management interface and I was thinking If i could configure another vme interface (e.g vme.10) on the VC and use one of the free MGT port on the switch.

     

    vme.0 is connected to ge interface on switch A

    vme.10 will be connected to ge interface on switch B

     

    Will it work? If yes, does Juniper recommend doing this i.e having multiple management interfaces?

     

    Thanks

    NO

    you can have only one vme it is available over any me. interface and you get directly connected to the RE, independent of input switch.

    regards

    Hi I agree with the last reply, 

     

    vme you can only have one, you could configure 2 me0 interfaces one for the master and one for the backup as explained here:

    vme stands for virtual management ethernet, it is basically a virtual interface that you can reach through any of the members of a VC. I personally think this is more efficient than configuring different IPs for the different members once on the master you ca use:

    >request session member <member id>

    to move between the different members of the VC.
