SNMP Community Configuration

The security device administrator can create up to three SNMP communities, with up to eight hosts in each community. Hosts must be listed individually; they cannot be specified as a range.

To Create a New Community

  1. Enter the following information:

Community Name: Specify the name of the group, or community, of administrators who can view data gathered by the SNMP agent and receive SNMP notifications of system events.

Permissions:

Write: Select to assign read-write privileges for MIB II data to the SNMP community. Otherwise, clear to assign read-only privileges.

Trap: Select to send notifications, or traps, to the community. The security device sends Cold Start/Link Up/Link Down traps to all hosts in communities that you set to receive traps.

Including Traffic Alarms: Select to send traffic alarms to the SNMP community.

Version: Select V1, V2C, or ANY. Each community can support SNMPv1, SNMPv2c, or both.

MIB Filter: Select the MIB Filter that you want to bind to the SNMP community. Select none if no MIB filter is configured for the SNMP community.

Enter the following information for each member of the community:

Hosts IP Address/Netmask: Enter the IP addresses and netmasks of the hosts—workstations or subnets—that you want to define as members of the community. By default, an SNMP community member has a 32-bit netmask (255.255.255.255), which defines it as an individual workstation. You can also define a host as a subnet. (Note: When you define an SNMP community member as a subnet, that member can poll the security device but cannot receive SNMP traps. To receive SNMP traps, the community member must be an individual workstation.)

Trap Version: Select V1 or V2C. If a community supports both versions of SNMP, you must specify a trap version for each community member.

Source Interface: The interface from which SNMP messages originate.
