Article ID: KB17821 KB Last Updated: 26 Feb 2020Version: 3.0
Summary:

This article provides information on how to enable or disable the Virtual Chassis Port (VCP) on a Virtual Chassis (VC) member of the EX4200, EX4500, and EX8200 VC. 

 

Symptoms:
  • In a production environment, you may have to disable a virtual-chassis port for troubleshooting purposes.

  • In a production or test environment, you can do the same when performing virtual-chassis active path failover.

  • You can also disable the unused VCP ports for security reasons, to ensure that no unauthorized user can connect an EX switch and make it a part of the virtual chassis.

 

Solution:
  • To disable the Virtual Chassis Port on a standalone switch:

    root# run request virtual-chassis vc-port set interface vcp-0 disable
    root# run request virtual-chassis vc-port set interface vcp-1 disable
  • To disable the Virtual Chassis Port on a VC member (in this example, member 1):

    root# run request virtual-chassis vc-port set interface member 1 vcp-0 disable
    root# run request virtual-chassis vc-port set interface member 1 vcp-1 disable
  • To enable a disabled Virtual Chassis Port on a standalone switch:

    root# run request virtual-chassis vc-port set interface vcp-0
    root# run request virtual-chassis vc-port set interface vcp-1
  • To enable a disabled Virtual Chassis Port on a switch, which is a part of the VC stack:

    root# run request virtual-chassis vc-port set interface member 1 vcp-0
    root# run request virtual-chassis vc-port set interface member 1 vcp-1 
  • To disable the VCP port on an EX8200 Virtual Chassis member:

    user@external-routing-engine> request virtual-chassis vc-port set interface vcp-0 member 0 disable
    user@external-routing-engine> request virtual-chassis vc-port set interface vcp-0 member 1 disable 
  • To enable the VCP port from EX8200 Virtual Chassis Member:

    user@external-routing-engine> request virtual-chassis vc-port set interface vcp-0 member 0
    user@external-routing-engine> request virtual-chassis vc-port set interface vcp-0 member 1
  • To disable the 10g LAG network port, which is acting as a VCP port, on an EX8200 Virtual Chassis member:

    user@external-routing-engine> request virtual-chassis vc-port set fpc-slot 4 pic-slot 0 port 1 member 0 disable
    user@external-routing-engine> request virtual-chassis vc-port set fpc-slot 4 pic-slot 0 port 1 member 1 disable
  • To enable the 10g LAG network port, which is acting as a VCP port, on the EX8200 Virtual Chassis member:

    user@external-routing-engine> request virtual-chassis vc-port set fpc-slot 4 pic-slot 0 port 1 member 0
    user@external-routing-engine> request virtual-chassis vc-port set fpc-slot 4 pic-slot 0 port 1 member 1
