Add a Switch Behind a Next-Generation Firewall

Before you add a site with a switch behind a next-generation firewall, ensure that the switch and the firewall are powered on and connected to each other.

To add a site with switch behind a next-generation firewall:

Select Resources > Site Management.
The Sites page appears.
Click Add and select Add On-Premise Spoke (Manual).
The Add On-Premise Spoke Site for Tenant-Name page appears.
Complete the configuration settings according to the guidelines provided in Table 1. Note
Fields marked with an asterisk (*) are mandatory.
Click Next.
A summary page is displayed.
Review the configuration and modify the settings, if needed, from the Summary tab.
Click OK to add the site.
The site activation job is initiated and the Site Activation: Site-Name page appears displaying the progress of the steps executed for activating the firewall device and the switch (when LAN capability is selected). The firewall device is activated first and then the process to activate the switch is initiated.
- 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.
  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.

Note

You can also add a site with LAN and next generation firewall capabilities using the site templates. For more information, see Adding On-Premise Spoke Sites by Using a Site Template.

Table 1: Fields on the Add On-Premise Spoke Site for Tenant-Name Page (Firewall and LAN)

Select Timezone	Select the time zone for the site.
WAN
Device Information
Serial Number	Enter the serial number of the firewall device. Note that the serial numbers are case-sensitive.
Auto Activate	Click the toggle button to enable or disable automatic activation of the device. This option is enabled by default.
Activation Code	If the Auto Activate feature is disabled, enter the activation code to manually activate the device. The activation code is provided by the administrator who adds the site.
Zero Touch Provisioning	Click the toggle button to enable or disable Zero Touch Provisioning (ZTP). This option is enabled by default. If ZTP is enabled, the Boot Image field is displayed and you must select an image that supports the Phone-Home client. During ZTP, the image on the firewall device is upgraded to the image that you select for the Boot Image. If ZTP is disabled, you must manually copy (by using CLI), the Stage-1 configuration on to the firewall device.
Boot Image	When the Zero Touch Provisioning field is enabled, select the boot image from the drop-down list to upgrade the image on the firewall device to a version that supports Phone-Home client. The boot image is the device image that was previously uploaded to the image management system. The boot image is used to upgrade the device when CSO starts the ZTP process. If the boot image is not provided, then the device skips the automatic upgrade procedure. The boot image is populated based on the device template that you have selected while creating a site. By default, the Use Image on Device option is selected.
In-band Management Port	Select the port that you want to configure as management interface and connect it to the management device. You can configure any of the ge-0/0/x ports, where x ranges from 0 to 14, as in-band management interfaces. This field is applicable only when a switch is behind a CPE (SD-WAN or a next generation firewall device).
Firewall Policies	Select the firewall policy that you want to deploy to the standalone firewall site. The firewall policy list is populated from the Configuration > Firewall > Firewall Policy page. Default: Factory_Default_Fw_Policy
NAT Policies	Select the NAT policy that you want to deploy to the standalone firewall site. The NAT policy list is populated from the Configuration > NAT > NAT Policies page. Default: Factory_Default_NAT_Policy
