SNMP terminology
SNMP terminology used in the configuration applet is explained in the following table.
Term Meaning
Community
Name
Both the SNMP management system and SNMP agent must be members of a
group so that SNMP messages can be passed between them. The logical name
assigned to such a group can be any combination of alphanumeric characters, and
is referred to as a community name. SNMP operations require a valid community
name; up to seven community names can be specified.
Community names, known only to registered users or administrators, provide the
security required by SNMP SET operations. The globally known “public” can be
used as a community name, but does not provide security. If no community is
specified, all SNMP requests will be honored.
The SNMP agent residing on the managed node accepts or rejects an SNMP
request based on the community name contained in the request. For example, an
agent configured with the community name “vertical” rejects all requests
containing any other community name.
Host
The management system requesting SNMP information from this Wave Server.
Trap
An unsolicited asynchronous message sent from an SNMP agent to a management
system. Traps are typically sent by the agent when a predefined condition or event
occurs. For details on such conditions and events, see Chapter 32, SNMP Agents.
Trap
Community
The string encoded in a trap message (packet) by the agent; placeholder for trap
destinations.
Like community name, the trap community name can be any combination of
alphanumeric characters; unlike community name, trap community names have
nothing to do with security. “Public” is fine to use as a default.
Trap
Destination
A specific network address (IP or DNS host name) to which a trap message is sent.
Up to five trap destinations can be added for each trap community.
