Management SonicWALL SNMP Support
SNMP (Simple Network Mana gement Prot ocol) is a network protocol used over User Datagram
Protocol (UDP) that allows network administrators to monitor the status of the SonicWALL Internet
security appliances and receive notification of any critical events as they occur on the network.
SonicWALL Internet security appliances support SNMP v1/v2c and all relevant Management
Information Base II ( MIBII) groups except egp and at . The SonicWALL replies to SNMP Get
commands for MIBII via any interface and supports a custom SonicWALL MIB for generating trap
messages. The custom SonicWALL MIB is available for download from the SonicWALL Website and
can be l oaded into third-par ty SNMP ma nagement software such as HP O penview, Tivoli, or SNMPC.
To configure SNMP in the SonicWALL Internet Security appliance, log into the SonicWALL
management interface. Click Access, then Management.
The SonicWALL SNMP agent generates two traps: Cold Start Trap and Alert Traps. Cold Start Traps
indicates the SonicWALL appliance is re-initializing itself so that the agent configuration or the
appliance can be altered. Alert Traps are based on the ex ist ing Son icWA LL al ert m essag es whi ch
allows the trap messages to share a common message string with the alerts. Accordingly, no trap
message can exist without a corresponding alert message.
