System Config
This section describes the configuration of several non-network features, such as HA,
SNMP, custom replacement messages, and Operation mode.
If you enable virtual domains (VDOMs) on the FortiGate unit, HA, SNMP, and replacement
messages are configured globally for the entire FortiGate unit. Changing operation mode
is configured for each individual VDOM. For details, see “Using virtual domains” on
page 103.
This section describes:
• HA
• SNMP
• Replacement messages
• Operation mode and VDOM management access
HA
FortiGate high availability (HA) provides a solution for two key requirements of critical
enterprise networking components: enhanced reliability and increased performance. This
section contains a brief description of HA web-based manager configuration options, the
HA cluster members list, HA statistics, and disconnecting cluster members.
If you enable virtual domains (VDOMs) on the FortiGate unit, HA is configured globally for
the entire FortiGate unit. For details, see “Using virtual domains” on page 103.
For complete information about how to configure and operate FortiGate HA clusters see
the FortiGate HA Overview, the FortiGate HA Guide, and the Fortinet Knowledge Center.
HA is not available on FortiGate models 50A and 50AM. HA is available on all other
FortiGate models, including the FortiGate-50B.
The following topics are included in this section:
• HA options
• Cluster members list
• Viewing HA statistics
• Changing subordinate unit host name and device priority
• Disconnecting a cluster unit from a cluster
HA options
Configure HA options so that a FortiGate unit can join a cluster or to change the
configuration of an operating cluster or cluster member.
To configure HA options so that a FortiGate unit can join an HA cluster, go to System >
Config > HA.
