Installed the uplink modules needed for the Virtual Chassis configuration.
Mounted the new switch in a rack.
Ensured that the preprovisioned Virtual Chassis configuration has an active master.
For more information, see Example: Configuring an EX4200 Virtual Chassis Using a
Preprovisioned Configuration File.
On the master, configured the Link Level Discovery Protocol (LLDP) on the uplink
module ports that will be used as VCPs. LLDP is configured by default but might have
been disabled. To configure LLDP, see Configuring LLDP (CLI Procedure).
Ensured that the new member switch has the factory-default configuration. If the new
member switch has been previously configured, revert its configuration to the factory
defaults. See Reverting to the Default Factory Configuration for the EX Series Switch.
Made a note of the serial number (the number is on the back of the switch). You will
need to edit the Virtual Chassis configuration to include the serial number of the new
member switch.
Edited the existing Virtual Chassis preprovisioned configuration to include the serial
number of the new member switch. The parameters specified in the master Virtual
Chassis configuration file are applied to the new member switch after it has been
interconnected through its uplink VCP to an existing member switch.
Prepared an existing member switch to interconnect with the new switch through an
uplink module port by configuring an uplink module port as a VCP on the existing
member switch.
Ensured that the operational modes of the uplink modules on the existing member
switch and the new member switch match.
Confirmed that the new member switch is powered off.
If the preceding conditions are not met, autoprovisioning will not work and you will need
to manually configure uplink module ports on the switch to be added to the configuration
to be VCPs. For more information, see Setting an Uplink Port on an EX Series Switch as a
Virtual Chassis Port (CLI Procedure).
To add a switch to an existing preprovisioned Virtual Chassis configuration using the
autoprovisioning feature:
Interconnect the unpowered new switch to one member of the existing Virtual Chassis
1.
configuration. Only connect one VCP on the unpowered new switch to a VCP on a
member switch in the existing Virtual Chassis at this point of the procedure.
Power on the new member switch.
2.
Confirm that the new member switch is now included in the Virtual Chassis
3.
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.
Cable the other VCP on the new member switch to the Virtual Chassis.
