SNMP Traps
An SNMP trap is generated by the Barracuda Link Balancer SNMP agent every five minutes if one
of the following conditions is noted:
• CPU temperature exceeded its threshold.
• System temperature exceeded its threshold.
• CPU fan is dead.
• System fan is dead.
• Firmware storage exceeded its threshold.
• Log storage utilization exceeded its threshold.
• WANx is down.
• WANx is up.
• WANx reached configured saturation threshold.

Traps are sent to the SNMP trap receivers that are specified on the

is sent every hour to the same email address.
