Getting serial numbers of cluster units
The following SNMP get commands use the MIB field name fgHaStatsSerial.<index> to get the serial number of each cluster unit. Where <index> is the cluster unit’s cluster index and 1 is the cluster index of the primary unit, 2 is the cluster index of the first subordinate unit, and 3 is the cluster index of the second subordinate unit.
The OID for this MIB field is 1.3.6.1.4.1.12356.101.13.2.1.1.2.1. The community name is public. The IP address of the FortiGate interface is 10.10.10.1.
The first command uses the MIB field name and the second uses the OID for this table and gets the serial number of the primary unit:
snmpget -v2c -c public 10.10.10.1 fgHaStatsSerial.1
snmpget -v2c -c public 10.10.10.1 1.3.6.1.4.1.12356.101.13.2.1.1.2.1
The second command uses the MIB field name and the second uses the OID for this table and gets the serial number of the first subordinate unit:
snmpget -v2c -c public 10.10.10.1 fgHaStatsSerial.2
snmpget -v2c -c public 10.10.10.1 1.3.6.1.4.1.12356.101.13.2.2.2
