Configuring a Virtual Chassis (J-Web Procedure)

To take advantage of the scalability features of EX4200 switches, you can configure a Virtual Chassis that includes up to 10 member switches. You can interconnect the member switches using the dedicated Virtual Chassis ports (VCPs) on the back of the switch. You do not have to configure the interface for the dedicated VCPs. If you want to interconnect member switches that are located in different racks or wiring closets, interconnect them using uplinks configured as VCP interfaces. See Setting an Uplink Module Port as a Virtual Chassis Port (CLI Procedure).

To configure a Virtual Chassis for EX Series switches using the J-Web interface:

  1. Select Configure > Virtual Chassis.

    Note: After you make changes to the configuration in this page, you must commit the changes for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes for details about all commit options.

  2. The properties you can configure are displayed.

    The first section of the Virtual Chassis Configuration page displays the Virtual Chassis member configuration. the display includes a list of member switches, their member IDs, and the mastership priority.

    The second section displays the operational status of the Virtual Chassis configuration, member details, and the dedicated and configured Virtual Chassis ports (VCPs).

  3. Enter information into the page as described in Table 1.
  4. Click one:
    • Add—To add a member's configuration to the Virtual Chassis configuration, click Add.
    • Edit—To modify an existing member's configuration, click Edit.
    • Delete—To delete the configuration of a member, click Delete.
  5. To configure an uplink as a VCP, select the member in the Virtual Chassis members list and select Action > Select Uplink Port as VCP. Select the port from the list.
  6. To delete an uplink VCP from a member, select the member in the Virtual Chassis members list and select Action > Delete Uplink Port as VCP.
