Add a Switch to an Existing SD-WAN Site Or Next-Generation Firewall Site

You can add one switch to an existing on-premise spoke site that already has a CPE or firewall device provisioned or an enterprise hub site, to provide LAN capability to the site. See Switch Behind a CPE or Next Generation Firewall Overview for details.

To configure more than one switch with an SD-WAN CPE or Next-Generation firewall, add a separate SD-LAN site and add multiple switches to the site.

You can manage the connectivity and configuration between the switches and the CPE or Next-Generation firewall by creating uplink ports to the CPE device or Next-Generation Firewall, either manually or by using configuration templates. See Add Switches to an Existing SD-LAN Site to add an SD-LAN site with multiple switches.

To add a switch to an existing site:

Procedure

  1. Select Resources > Site Management.

    The Sites page appears.

  2. Do one of the following:
    • Procedure

      1. Select the site to which you want to add the switch.
      2. Click Add > Add Switch.

        The Add Switch page appears.

    • Procedure

      1. Click the Site-Name link of the site (to which you want to add the switch) in the Sites column.

        The Site-Name page appears.

      2. On the Devices tab, click Add Switch.

        The Add Switch page appears.

  3. Complete the configuration according to the guidelines provided in Table 46.

    Note Fields marked with asterisk (*) are mandatory.

  4. Review the configuration from the Summary tab.
  5. (Optional) Click the Edit links within the summary to go directly to a specific page of the wizard and modify the configured settings.
  6. Click OK to add the switch to the site.

    The site activation process is initiated and the Site Activation: Site-Name page appears displaying the progress of the steps executed for activating the CPE and the switch.

    • If the Zero Touch Provisioning (ZTP) toggle button is enabled (default), CSO pushes the stage-1 and stage-2 configurations and provisions the switch.

      This process occurs immediately after the activation process, for which you entered the activation code or selected auto-activation.

      Note Stage-1 configuration is the initial configuration that allows basic connectivity to a device, which is pushed to the device.

      The configuration that is pushed to the device after it has connected to CSO is called stage-2 configuration.

    • If you disabled the Zero Touch Provisioning (ZTP) toggle button, you must manually configure the stage-1 configuration (as provided by CSO) on the switch.

      Procedure

      To manually configure the stage-1 configuration:

      1. On the Site Activation: Site-Name page, the Click to copy stage-1 configuration link appears after the Prestage Device step completes successfully.
      2. Click the Click to copy stage-1 configuration link.

        The stage-1 configuration page appears displaying the stage-1 configuration to be copied to the EX Series device.

      3. Copy the stage-1 configuration and log in to the console of the EX Series switch.
      4. Enter the configuration mode, paste, and commit the configuration.

        After the stage-1 configuration is committed, the switch has the outbound SSH configuration to connect with CSO.

        CSO then provisions the switch.

Table 46 provides guidelines on using the fields on the Add Switch page.

Table 46: Fields on the Add Switch Page

Field

Description

Device Profile

Device Name

Enter a name for the switch.

You can use alphanumeric characters and hyphen (-). The maximum length allowed is 15 characters.

Device Type

Select the type of switch—EX2300, EX3400, EX4300, EX4600, and EX4650.

Device Model

Select the model for the switch you specified in the Device Type field.

CPE Settings

Trunk Ports

Select at least two trunk ports on the CPE device to connect with the switch, which are used for the following:.

  • LAN traffic between the switch and the CPE or firewall.

  • Management traffic for in-band management of the switch.

Note: The ae0 port of the SRX Series devices is used as the trunk port for communication with the switch.

Switch Management Subnet

Specify the subnet that the DHCP can use to assign IP addresses. The DHCP server runs on the following ports:

  • Trunk ports to provide DHCP information to all devices connected to the switch and to the in-band management port, switch management port, and LAN ports on the CPE or firewall.

  • Out-of-band management port on the CPE or firewall to provide DHCP information to the management port on the switch.

  • LAN ports on the CPE or firewall to provide information to the devices connected to the CPE or firewall LAN ports.

Switch Details

Virtual Chassis

This toggle button is disabled for an SD-WAN site and Next-Generation Firewall site.

You can add a Virtual Chassis only to an SD-LAN site.

Serial Number

Specify the serial number of the physical switch.

You can either view the serial number on the label that is present on the rear panel of the switch or log in to the CLI of the switch in operational mode and enter show chassis hardware.

The serial number is a case-sensitive, alphanumeric string.

Zero Touch Provisioning

Click to enable or disable ZTP on the switch.

If you disable ZTP, you must manually copy and paste the Stage-1 configuration on the switch during site activation. See Step-by-Step Procedure for details

Note:

  • Only EX Series switches running 18.4R2.7 or 18.4R3.3 firmware support ZTP.

  • EX4600 and EX4650 switches do not support Phone-Home client. You must disable ZTP and manually configure the stage-1 configuration on the switches.
