  • 1.  Is "Backup" role required if I only have two switches?

    Posted 04-03-2018 09:42

    Hi,

    I only have two EX4200 series switches. By defauly, one is set to "Master", and another one is "Backup".

    I don't need a backup. How to configure the "Backup" to be "Line-card"?

    Any info is appreciated!

     

    Thanks!

    Hi,

     

    You may set the member role as linecard. Then that member wont be backup /master anymore.

    I did follow the steps in the doc you mentioned.

    See below the commands I tried.

    I ran these commands when the Matser one is powered on and the second switch is powered off as it is mentioned in the doc.

     

    root@:RE:0% set preprovisioned

    root@:RE:0% set virtual-chassis member 1 serial-number BM0211335826 role line-card

    set: Syntax Error.

    root@:RE:0% set member 1 serial-number BM0211335826 role line-card

    set: Variable name must begin with a letter.

    You are not in CLI or edit mode:

     

    root@test:RE:0% cli
{master:0}
root@test> edit 
Entering configuration mode

{master:0}[edit]
root@test# set virtual-chassis preprovisioned 

{master:0}[edit]
root@test# set virtual-chassis member 1 serial-number BM0211335826 role line-card 

{master:0}[edit]
root@test# commit

    Thank you so much for pointing it out! I am able to change the Backup role to line-card!

    Next, I'll be testing my switches...
