Adding an EX4200 Switch to a Preprovisioned EX4500 Virtual Chassis or a Preprovisioned Mixed EX4200 and EX4500 Virtual Chassis (CLI Procedure)

 

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

To add an EX4200 switch to an EX4500 Virtual Chassis or a mixed EX4200 and EX4500 Virtual Chassis that was configured using a preprovisioned configuration:

  1. Power on the EX4200 switch that will be added to the Virtual Chassis.
  2. Set the Virtual Chassis mode to mixed:
    user@switch> request virtual-chassis mode mixed
  3. Reboot the EX4200 switch.
    user@switch> request system reboot
  4. Log in to the EX4500 Virtual Chassis or the mixed EX4200 and EX4500 Virtual Chassis.
  5. (EX4500 Virtual Chassis only) Set the Virtual Chassis mode to mixed for all Virtual Chassis member switches:
    user@switch> request virtual-chassis mode mixed all-members
    Note

    Each member switch will already have been configured in mixed mode in a mixed EX4200 and EX4500 Virtual Chassis.

  6. (EX4500 Virtual Chassis only) Reboot all member switches in the EX4500 Virtual Chassis:
    user@switch> request system reboot all-members
  7. Add the EX4200 switch to the preprovisioned configuration:
    [edit virtual-chassis]

    user@SWA–0# set member 5 serial-number serial-number role role

  8. If you are replacing an EX4500 switch in the routing-engine role with an EX4200 switch, change the role of the EX4500 switch to line-card:
    [edit virtual-chassis]

    user@switch# replace member 0 serial-number serial-number role routing-engine with member 0 serial-number serial-number role line-card

    user@switch# replace member 1 serial-number serial-number role routing-engine with member 1 serial-number serial-number role line-card
  9. Commit the configuration:
    user@switch# commit synchronize
  10. Cable one dedicated or user-configured Virtual Chassis port (VCP) on the new member switch to the existing Virtual Chassis. See Connecting a Virtual Chassis Cable to an EX4200 Switch or Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual Chassis Port.

  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.
