Configure and Activate a High Availability Site
For supported software information, click here.
To configure a high availability (HA) site in Titan Portal, set up the appliance wiring on two appliances and then configure the site. You must use identical license types on two identical appliances to create an high availability pair (device model and software security license tier must be the same). You must deploy and activate each device separately.
Install High Availability Wiring
Install the wiring on the appliances:
- Wire the two appliances before you configure them for high availability. When wiring the device for high availability, the ports are divided into three sections. WAN ports are the lower numbered ports on the left. LAN ports are the higher numbered ports on the right. Assign a port in the middle, which is called a cross-connect port. The cross-connect port marks the boundary between the WAN and LAN ports.
- Connect the WAN ports. WAN ports must be connected starting with port 0, then port 1, and so on. WAN ports are always the lower port numbers. Attach port 0 on both devices to a WAN.
- Determine the cross-connect port number.
- If both devices use the same number of ports for WAN connections, assign the next port number after the highest WAN port number as the cross-connect port number. For example, if you use ports 0 and 1 as WAN ports on both devices, then use port 2 as the cross-connect port.
- If the devices use an unequal number of WAN connections, use the device with the larger number of WAN connections to determine the cross-connect port number. For example, if the first device uses ports 0 and 1 as WAN ports and the second device uses only port 0 as a WAN port, then use port 2 as the cross-connect port on both devices. In this case, port 1 on the second device is unused.
- Connect the cross-connect port on the first device to the cross-connect port on the second device using a Cat6 Ethernet cable. Again, you must use the same port number on both devices for the cross-connect.
- Connect the LAN ports. The higher numbered ports are used as LAN ports. Connect the first LAN port (that is, the port immediately to the right of the cross-connect port) to the local LAN. This port is used for Virtual Router Redundancy Protocol (VRRP) communication.
The following diagram shows an example configuration assigning one WAN port, a cross-connect port, and one LAN/VRRP port on each device in an high availability pair. Here, both devices use the same number of ports for WAN connections, and you should install a Cat6 Ethernet cable (not shown) to connect the two cross-connect ports.
To enable an HA cross-connect port, see Configure an HA Cross-Connect Port.
Create a High Availability Site
To create, deploy, and activate a high availability site:
Note: When you deploy high availability devices, you must click the high availability box before deploying the site. If a device configuration is already deployed for a site and you drag and drop another license into the site within the honeycomb on the dashboard, high availability is not autoconfigured. You first need to undeploy the device and then redeploy it. You can undeploy primary and secondary devices Individually. See Undeploy a Device Configuration.
- In the Titan Portal Dashboard, click Configure in the left menu bar to display the Configure dashboard.
- Click Available Licenses in the device (site) menu bar to display available licenses, and then select a license type. To configure high availability, you must have at least two licenses of the same type.
- Drag and drop a license onto the dashboard. The New Site Configuration window displays.
- Enter site configuration information.
- Enter the site name and location information.
- Click high availability Mode.
- Click Save.
- The honeycomb displays the new site with two devices. Site A is on the left, and Site B is on the right. The device marked in pink is the primary device.
-
Create and save configurations for each device separately. The first LAN, which is the next port after the cross-connect port, is a shared LAN, and you can configure it only on the first device. Configuring the first LAN configures the LAN on both devices. If one device fails, the other continues to operate the LAN. For information about creating and saving a configuration, see Configure Security and Configure Traffic Steering.
- Deploy the device configurations:
- In the honeycomb for the new site, click the device on the left to display its options card, and then click Configure to open a site configuration window.
- Click Deploy, and then choose an activation method.
- Repeat these steps to deploy the configuration for the device on the right, choosing an identical activation method.
- Activate each device using the method selected in the previous step. You must activate each device separately. For WiFi and GZTP activation see Activate an Appliance. For Versable activation, see Activate Using Versable section in the Titan Mobile documentation.
- After the site is activated, the administrative state for the site in the honeycomb displays as active.
To remove a high availability site, see Remove a Site in Configure and Activate a Site.
Note: For HA primary and secondary devices, you cannot deactivate the devices. You must undeploy and then redeploy the device to activate it again.
