Configuring SNMP Access Control
SNMP Access Control defines how SNMP will controls access to MIB objects.
In SNMP versions 1 and 2c, access control is configured by a
community-based model. A community associates an SNMP agent and an
SNMP management application. You assign a name to the community, and
the agent and management application use this name to authenticate SNMP
messages exchanged between them.
In SNMP version 3, access control is configured by a user-context model.
These models are described in the sections that follow.
Configuring access control for MIB views and groups is common to all
versions.
SNMP access control follows a hierarchy and it is recommended that you
perform configuration functions in the following order:
1. Configure SNMP Access Views.
2. Configure SNMP Groups.
3. Configure Models, as follows:
a Configure SNMPv1, v2c Communities, and/or
b Configure SNMPv3 Users and Contexts
