General SNMP Message Format
General SNMP Message Format
Each PDU is embedded in a message, or packet, beginning with a version number and
a community name. The
version number
identifies the version of SNMP being
implemented; currently, this value is always 1 for NonStop SNMP messages. The
community name
identifies one or more SNMP managers; it is used for access
control. Following the version and community identifiers is one of the five types of
PDUs.
Request PDUs
The three kinds of request PDUs have the same format as the response PDU, but the
error-status
and
error-index
fields are always set to 0. The
request-id
uniquely
identifies individual requests.
Variable-bindings
are a list of variable names and
corresponding values.
