If you are using SNMPv3 to monitor the firewalls, note that the SNMPv3 Engine ID is synchronized
between the HA pair. For information on setting up SNMP, see
Forward Traps to
an SNMP Manager. Because the EngineID is generated using the firewall
serial number, on the VM-Series firewall you must apply a valid license in order
to obtain a unique EngineID for each firewall.
