SNMP

SNMP (Simple Network Management Protocol)is a network protocol used over User Datagram Protocol (UDP) that allows network administrators to monitor the status of the SonicWall Security Appliance and receive notification of critical events as they occur on the network. The SonicWall Security Appliance supports SNMP v1/v2c/v3 and all relevant Management Information Base II (MIB-II) groups except egp and at.

SNMPv3 expands on earlier versions of SNMP and provides secure access to network devices by means of a combination of authenticating and encrypting packets.

To enable the SNMP engine

1. Navigate to Device | Settings | SNMP
2. In the SNMP tab, enable SNMP and click Configure.
3. On the General tab, configure the SNMP View.

   

4. On the Advanced tab, Mandatory Require SNMPv3 is enabled by default.

   SNMPv3 is enabled by default. If you want to use SNMPv1 or SNMPv2, you need to disable the Mandatory Require SNMPv3 setting and add a Get Community Name while configuring SNMP view in General tab. However, it is highly recommended to use SNMPv3, as it offers the maximum security for SNMP management.

5. On the Users/Groups and Access tabs add custom users, groups and accesses with appropriate security levels.

6. Click OK.

   The SNMPv3 security options are now used in processing packets.

SNMP must be enabled on the interface you wish to monitor from or in the VPN tunnel configuration, if monitoring a remote firewall. For more information about configuring SNMP, refer to SonicOS 8 Device Settings Administration Guide.
