Configuring High Availability
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 firewalls resources.
Both cluster members must use the same HA VLAN, and different clusters
on the same subnet can also use the same HA VLAN or a different
HA VLAN.
5. Under HA IP Configuration, for IP Address and Subnet Mask, type the IP
address and subnet mask for HA management traffic. Each cluster mem-
ber must have a unique address on the HA VLAN.
