NOTE: If you are using a preprovisioned configuration, the member ID is automatically assigned to the member's serial number in the configuration file.

Adding a New Switch to an Existing Preprovisioned Virtual Chassis Configuration Using Autoprovisioning

Before you begin, be sure you have:

■

■

■

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 a 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) or Configuring LLDP (J-Web 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 (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. You can specify the role of the new member switch when you add its serial number to the Virtual Chassis configuration file. 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.

Interconnected the existing switch with the new switch using the appropriate cable.

If these 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 Module Port as a Virtual Chassis Port (CLI Procedure).
