Adding an EX4500 Switch to a Preprovisioned 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.

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

  1. Power on the EX4500 switch with the installed Virtual Chassis module.
  2. Verify the PIC mode setting:
    user@switch> show chassis pic-mode
  3. Note

    Step 3 is required only if you are using the dedicated VCPs on the Virtual Chassis module of the EX4500 switch to connect the Virtual Chassis.

    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 the Virtual Chassis.
    user@switch> request system reboot all-members
  9. Log in to the EX4200 Virtual Chassis after the reboot is complete.
  10. On the master switch, add the EX4500 switch to the preprovisioned configuration:
    [edit virtual-chassis]

    user@switch# set member member-id serial-number serial-number role role

  11. If you are using the EX4500 switch in the master role in place of an EX4200 switch, change the EX4200 switch in the routing-engine role to the line-card role:
    [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
  12. Commit the configuration:
    user@switch# commit synchronize
  13. Interconnect the EX4500 switch to one member of the existing Virtual Chassis configuration. See Connecting a Virtual Chassis Cable to an EX4200 Switch and Connecting a Virtual Chassis Cable to an EX4500 Switch.

    Connect only one VCP on the EX4500 switch to a VCP on a member switch in the existing Virtual Chassis at this point of the procedure.

  14. Confirm that the new member switch is now included in the Virtual Chassis configuration by checking the front-panel LCD for the member ID. It should display a member ID in the range from 0 through 9. The member ID is automatically assigned to the new member switch's serial number in the configuration file.
  15. Cable the other VCP on the Virtual Chassis of the EX4500 switch to the Virtual Chassis.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.
