SNMPv3
SNMPv3 is the third version of the Simple Network Management Protocol. The
architecture comprises the following:
■ entities that may be either managers, agents, or both
■ a management information base (MIB)
■ a transport protocol
At least one manager node runs the SNMP management software in every configuration.
Managed devices such as routers, servers, and workstations are equipped with an agent
software module. The agent provides access to local objects in the MIB that reflect activity
and resources at the node. The agent also responds to manager commands to retrieve
values from, and set values in the MIB.
SNMP MIB Views for SNMPv3
An SNMP MIB view is a arbitrary subset of objects in the MIB. Objects in the view may be
from any part of the object name space, and not necessarily the same sub-tree.
SNMP Groups
Groups were introduced as part of SNMPv3. They are the means by which users are
assigned their views and access control policy. Once a group has been created, users can
be added to them. In practice a number of groups would be created, each with varying
views and access security requirements. Users would then be added to their most
appropriate groups. Each Group name and Security Level pair must be unique within a
switch.
SNMP Users
Users were introduced as part of SNMPv3. From a system perspective a user is represented
as an entity stored in a table that defines the access and authentication criteria to be
applied to access or modify the SNMP MIB data.
Note SNMP Target Addresses and Target Params in SNMPv3 are not currently
supported in Alliedware Plus software.
