Prepare a Virtual Chassis for Onboarding to CSO

 

This topic provides steps on how to prepare a Virtual Chassis for onboarding to CSO. CSO supports the onboarding and provisioning of the following Virtual Chassis:

  • EX2300 Virtual Chassis

  • EX3400 Virtual Chassis

  • EX4300 Virtual Chassis

  • EX4600 Virtual Chassis

  • EX4650 Virtual Chassis

Setting up a Virtual Chassis for Provisioning

You can provision a Virtual Chassis in one of the following ways:

  • Autoprovisioning: The Virtual Chassis determines the roles (primary, backup, and line card) of the member devices.

  • Preprovisioning: You determine the roles (primary, backup, and line card) of the member devices in the Virtual Chassis.

Before you provision a Virtual Chassis, ensure that:

  • All members of the Virtual Chassis are wired and working; that is, the Virtual Chassis Ports (VCP) on the member devices are connected to each other.

  • Virtual Chassis mode is enabled on all the member devices.

  • Virtual Chassis management entity on all member devices can communicate with CSO.

For information about the number of member devices allowed in each Virtual Chassis, see Members Allowed in a Virtual Chassis.

Setup a Virtual Chassis for Autoprovisioning

To setup a Virtual Chassis for autoprovisioning:

  1. Decide the number of member devices in the Virtual Chassis.
  2. If you’ve added EX3400, EX4300, EX4600, or EX4650 devices as Virtual Chassis, interconnect all the corresponding member devices through Virtual Chassis ports (VCPs).

    If you’ve added EX2300 devices as Virtual Chassis, configure the 10 Gbps Ethernet ports as VCPs manually (through CLI) and interconnect the member devices.

    Note

    At this point, do not power on any member devices in the Virtual Chassis.

  3. Decide which member device acts as the primary and power on only this device first.Note
    • Remember the serial number of the primary device in the Virtual Chassis. This serial number is required during the site activation workflow to add this Virtual Chassis in CSO.

    • For ZTP to be successful, the primary device should always be designated as Member 0. You must specify the same serial number in the Member 0 field in CSO.

  4. Wait until the primary device completes booting.

    After booting is complete, the LCD panel on this device displays a menu that includes the JUNOS OS version loaded on the device, status of VCPs, status of power supplies, and so on.

  5. Power on the remaining member devices one after the other.
  6. Wait until all the member devices complete booting.

    After booting is complete, you can confirm that the Virtual Chassis is fully formed when all the LEDs on the VCPs are ON.

  7. Connect the primary and backup device to the Internet through the management port or uplink port.
  8. Verify the connectivity from the primary device to CSO or to any host on the Internet by using ping or telnet to Juniper redirect server on port 443.

Setup a Virtual Chassis for Preprovisioning

To setup a Virtual Chassis for preprovisioning:

  1. Decide the number of member devices in the Virtual Chassis.
  2. If you’ve added EX3400, EX4300, EX4600, or EX4650 devices as Virtual Chassis, interconnect all the corresponding member devices through Virtual Chassis ports (VCPs).

    If you’ve added EX2300 devices as Virtual Chassis, configure the 10-Gbps Ethernet ports as VCPs manually and interconnect the member devices.

    Note

    At this point, do not power on any member devices in the Virtual Chassis.

  3. Decide which member device acts as the primary and which member device acts as the backup.
  4. Of the two devices, power on the device that you want to select as the primary (Member 0), and wait until it completes booting.

    After booting is complete, the LCD panel on this device displays a menu that includes the JUNOS OS version loaded on the device, status of VCPs, status of power supplies, and so on.

    Note
    • Remember the serial numbers of all the devices in the Virtual Chassis. These serial numbers will be needed in the site activation workflow to add this Virtual Chassis in CSO.

    • For ZTP to be successful, the primary should always be designated as Member 0. You must specify the same serial number in the Member 0 field in CSO.

  5. Power on the device that you want to select as the backup and wait until it completes booting.

    After booting is complete, the LCD panel on this device displays a menu that includes the JUNOS OS version loaded on the device, status of VCPs, status of power supplies, and so on.

  6. Power on the remaining member devices one after the other.
  7. Wait until all the member devices complete booting.

    After booting is complete, you can confirm that the Virtual Chassis is fully formed when all the LEDs on the VCPs are ON.

  8. Connect the primary and backup device to the Internet through the management port or uplink port.
  9. Verify the connectivity from the primary device to CSO or to any host on the Internet by using ping or telnet to Juniper redirect server on port 443
