Configuring High Availability
To configure HA settings, complete the following:
1. Back up the startup-config on the cluster master. Should you need to
restore the startup-config, remember that it does not include the HA
settings.
a. On the cluster master, select System > Maintenance. Then click the
Back Up/Restore tab.
b. Click Back Up and save the configuration to your workstation.
2. Select System > Settings and click the High Availability tab.
Figure 8-2. System > Settings > High Availability Window
3. Select a Cluster Scheme. If you do not plan to configure HA at this time,
you should select None and configure the next section.
4. Under HA IP Configuration, for VLAN ID, type the ID number of the VLAN
that will manage HA traffic. The default HA management VLAN is VLAN 1,
but you should change the HA VLAN from the default to prevent unwanted
multicast traffic from occupying the firewall’s resources.
