Adding an EX4500 Switch to a Nonprovisioned EX4200 Virtual Chassis (CLI Procedure)

 

An EX4500 switch can be added to an EX4200 Virtual Chassis to create a mixed EX4200 and EX4500 Virtual Chassis.

This topic explains how to add an EX4500 switch to an already configured and operational EX4200 Virtual Chassis that was configured using a nonprovisioned configuration.

Before you begin adding EX4500 switches to the Virtual Chassis:

  • Ensure that a Virtual Chassis module is installed in the EX4500 switch.

To add an EX4500 switch to an EX4200 Virtual Chassis that was configured using a nonprovisioned configuration:

  1. Power on the EX4500 switch.
  2. Verify the PIC mode setting:
    user@switch> show chassis pic-mode
    Note

    This step is required only if you are using the dedicated VCPs on the Virtual Chassis module of the EX4500 switch to connect the Virtual Chassis.

  3. If the PIC mode was not set to Virtual Chassis mode, set the PIC mode to Virtual Chassis mode:
    user@switch> request chassis pic-mode virtual-chassis
  4. Set the Virtual Chassis mode to mixed:
    user@switch> request virtual-chassis mode mixed
  5. Reboot the EX4500 switch.
    user@switch> request system reboot
  6. Log in to the EX4200 Virtual Chassis.
  7. Set the Virtual Chassis mode to mixed for all member switches:
    user@switch> request virtual-chassis mode mixed all-members
  8. Reboot all member switches in the Virtual Chassis.
    user@switch> request system reboot all-members
  9. After all members have rebooted, interconnect one dedicated VCP on the EX4500 switch with one dedicated VCP of a member EX4200 switch in the EX4200 Virtual Chassis. . See Connecting a Virtual Chassis Cable to an EX4200 Switch and Connecting a Virtual Chassis Cable to an EX4500 Switch.Note

    You can also connect an EX4500 switch into the Virtual Chassis by configuring an uplink port as a VCP. See Setting an Uplink Port as a Virtual Chassis Port on an EX4500 or EX4550 Switch (CLI Procedure).

  10. Log in to the Virtual Chassis.
  11. Wait for the new switch to become operational in the Virtual Chassis. Monitor the show virtual-chassis command output to confirm the new switch is recognized by the Virtual Chassis and is in the Prsnt state.Caution

    If you immediately cable both VCPs on the new switch into the existing Virtual Chassis at the same time, a member switch that was already part of the Virtual Chassis might become nonoperational for several seconds. Network traffic to this switch is dropped during the downtime.

    The member switch will return to the normal operational state with no user intervention, and normal operation of the Virtual Chassis will resume after this downtime.

  12. Cable the other dedicated or user-configured VCP on the new member switch to the Virtual Chassis.
  13. (Optional) Set the mastership priority of the EX4500 switch. The switches with the highest mastership priorities assume the master role and backup roles.
    [edit virtual-chassis]

    user@switch# set member member-id mastership-priority mastership-priority

  14. (Optional) From the master switch, set the mastership priority of the other member switches:
    [edit virtual-chassis]

    user@switch# replace member member-id mastership-priority mastership-priority with member member-id mastership-priority mastership-priority
