Procedure to add a new member to a Juniper stack.

‎08-02-2016 10:20 AM

                Adding a new member to a Juniper stack.

 

  1. Upgrade/Downgrade the Junos SW Version to match the stack you’re adding to.
  2.  
  3. Obtain the Serial Number of the new chassis being installed.
    1. CLI:  show chassis hardware
  4. Mount the new chassis to the rack and power it up.
    1. DO NOT connect VC Cables yet.
  5. Login to the stack that is in production and set the new chassis’ Serial Number to its corresponding Member # and as a “line-card”.  (Example: if this is for a current stack of 3, then the new member will become Member 3)
    1. [edit virtual-chassis] # set member x serial-number abc123 role line-card
  6. Connect new chassis to the stack via VC cables in back.
  7. Verify that the new chassis is present and that it indicates that it’s a “line-card” LC using CLI “ show virtual chassis”.

Hi,

 

What if I do exactly that but the VC ports stay "down"

 

Current Stack:

fpc0:
--------------------------------------------------------------------------
Interface Type Trunk Status Speed Neighbor
or ID (mbps) ID Interface
PIC / Port
0/50 Configured -1 Down 40000
0/52 Configured -1 Up 40000 1 vcp-255/0/53

fpc1:
--------------------------------------------------------------------------
Interface Type Trunk Status Speed Neighbor
or ID (mbps) ID Interface
PIC / Port
0/53 Configured -1 Up 40000 0 vcp-255/0/52

 

New member to add:

localre:
--------------------------------------------------------------------------
Interface Type Trunk Status Speed Neighbor
or ID (mbps) ID Interface
PIC / Port
0/50 Configured -1 Down 40000

Hello alchemy24,

 

What is the hardware platform?

Do you have same JunOS version on all boxes?

Have you tried to swap cable and/or transceivers?

 

Thanks,

Deimos.

Hi,

 

I finally found the problem.

When I listed the config on both switch (by running the "show | display set", I was getting the same version 18.1R3.3.

But when running "show version" We could see that the switch I was trying to add had the qfx-5e package.

This was causing the version mismatch.

Hello alchemy24,

 

Seems, I was right when I asked: "Do you have same JunOS version on all boxes?"

I will be grateful if you mark my previous message as a solution.

 

Thanks,

Deimos.
