devices that do not know the proper community name are precluded from SNMP
operations, network management personnel also have used the community name as
a weak form of authentication.

The SNMP PDU has the following fields:

PDU type --

Specifies the type of PDU being transmitted.

Request-ID --

Associates requests with responses.

Error-status --

Indicates an error and an error type. In SNMPv2 GetBulk operations,

this field becomes a NonRepeaters field. For these operations, this field defines the
number of request-ed variables listed that should be retrieved no more than once
from the beginning of the request. The field is used when some of the variables are
scalar objects with only one variable.

Error-index --

Associates the error with a particular object instance. In SNMPv2

GetBulk operations, this field becomes a Max Repetition
this field defines the maximum number of times that other variables beyond those
specified by the NonRepeaters field should be retrieved.

Variable-bindings --

Comprises the data of an SNMP PDU. Variable bindings

associate particular object instances with their current values.

Like SNMPv1 messages, SNMPv2 messages (shown in
