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
The Add On-Premise Spoke Site for Tenant-Name page appears.
- Complete the configuration settings according to the guidelines
provided in Table 1.
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.
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:
- On the Site Activation: Site-Name page, the Click to copy stage-1 configuration link appears after the Prestage Device step completes successfully.
- 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.
- Copy the stage-1 configuration and log in to the console of the EX Series switch.
- 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.
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)
Enter a unique name for the firewall site. You can use alphanumeric characters and hyphen (-); the maximum length is 10 characters.
Select a site group to which you want to assign the site.
Select the WAN capabilities as Next Gen Firewall for the site.
Select the LAN capability as LAN for the site.
Address and Contact Information
Enter the street address of the site.
Enter the name of the city where the site is located.
Select the state or province where the site is located.
Enter the postal code for the site.
Select the country where the site is located.
You can click the Validate button to verify the address that you specified:
Enter the name of the contact person for the site.
Enter the e-mail address of the contact person for the site.
Enter the phone number of the contact person for the site.
Click Next to continue.
Name Server IP List
Enter one or more IPv4 addresses of the DNS server. To enter more than one DNS server address, type address, press Enter, and then type the next address, and so on. DNS servers are used to resolve hostnames into IP addresses.
Enter the fully qualified domain names (FQDNs) or IP addresses of one or more NTP servers. Example: ntp.example.net The site must have DNS reachability to resolve the FQDN during site configuration.
Select the time zone for the site.
Enter the serial number of the firewall device. Note that the serial numbers are case-sensitive.
Click the toggle button to enable or disable automatic activation of the device. This option is enabled by default.
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.
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).
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.
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.
Click the toggle button to automatically import firewall policies and NAT policies from a next generation firewall device to CSO. By default, this field is disabled.
Note: This field is available only when Zero Touch Provisioning is disabled.
Enter a name for the switch. You can use alphanumeric characters and hyphen (-). The maximum length allowed is 15 characters.
Select the type of switch—EX2300, EX3400, EX4300, EX4600, and EX4650.
Select the device model for the switch that you specified in the Device Type field.
The models vary in the number and type of ports the switch contains. For example, If you selected EX3400, select a model such as EX3400-24P, EX3400-48P, EX3400-24T among others.
Select at least two trunk ports on the CPE device to connect with the switch. The trunk ports are used for the following:
Switch Management Subnet
Specify the subnet that the DHCP can use to assign IP addresses. The DHCP server runs on the following ports:
Specify the serial number of the switch
The serial number is a 12-digit number present on the rear panel of the switch.
Click the toggle button to enable or disable automatic activation of the switch. When you enable this field, zero-touch provisioning of the switch is automatically triggered when the device communicates with CSO.
Note: You must physically connect the switch to the CPE device (firewall) and power it on for the switch to be automatically activated when you enable this option.
When the Auto activate field is disabled, enter the activation code to be used for manually activating the switch.
For information, see Manually Activating a Switch.
Zero Touch Provisioning
Click the toggle button to enable or disable zero-touch provisioning (ZTP) of 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.
