Adding an EX4600 Switch to a Mixed or Non-mixed Virtual Chassis

You can use this procedure to add an EX4600 switch to a mixed or non-mixed Virtual Chassis or to add an EX4300 switch to an existing mixed EX4300 and EX4600 Virtual Chassis. For EX4650 Virtual Chassis, which is more like a QFX5120 Virtual Chassis than an QFX4600 Virtual Chassis, see Adding a New Switch to an Existing EX4650 or QFX Series Virtual Chassis.

Before you begin, be sure you have:

• Mounted the new switch in a rack.

• Determined which ports you will use as Virtual Chassis ports on the new switch, and the member ports in the existing Virtual Chassis to which you will interconnect the new switch.

• If you are expanding a preprovisioned configuration:

  • 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.

    Note:

    Serial number values are case-sensitive.

  • Edited the existing Virtual Chassis configuration to include the serial number of the new member switch. The parameters specified in the primary Virtual Chassis configuration file are applied to the new switch after it has been interconnected to an existing member switch.

  • (If you are using the autoprovisioning feature to add a member switch to an existing preprovisioned Virtual Chassis) Confirmed that the member ports in the Virtual Chassis to which you will interconnect the new switch are not already configured as VCPs. One condition for automatic VCP conversion is that the ports on both sides of the new link must not already be configured as VCPs. See Automatic Virtual Chassis Port (VCP) Conversion for details.

• (Optional) Configured Ethernet interfaces on different member switches into the same LAG. See Example: Configuring Aggregated Ethernet High-Speed Uplinks Between an EX4200 Virtual Chassis Access Switch and an EX4200 Virtual Chassis Distribution Switch.

  An active member switch might temporarily go down before coming back up as part of this procedure. Having traffic load-balanced across member switches using a LAG helps alleviate traffic loss during this procedure.
