To Create a New CommunityThe NetScreen device administrator can create up to three (3) SNMP communities, with up to eight (8) hosts in each community. Hosts must be listed individually; they cannot be specified as a range.
To Create a New CommunityEnter the required information:
Community Name: The name of the group, or "community," of administrators who can view data gathered by the SNMP agent and receive SNMP notification 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 NetScreen 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.
Enter the following for each community member:
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 NetScreen device but it 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.
