Configuring SNMP
This chapter provides an overview of the Simple Network Management Protocol (SNMP) and guides you
through the configuration procedure.
Overview
SNMP is an Internet standard protocol widely used for a management station to access and operate the
devices on a network, regardless of their vendors, physical characteristics, and interconnect
technologies.
SNMP enables network administrators to read and set the variables on managed devices for state
monitoring, troubleshooting, statistics collection, and other management purposes.
FIPS compliance
The device supports the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for features,
commands, and parameters might differ in FIPS mode and non-FIPS mode. For more information about
FIPS mode, see Security Configuration Guide.
SNMP framework
The SNMP framework comprises the following elements:
• SNMP manager—Works on an NMS to monitor and manage the SNMP-capable devices in the
network.
• SNMP agent—Works on a managed device to receive and handle requests from the NMS, and
sends notifications to the NMS when events, such as an interface state change, occur.
• Management Information Base (MIB)—Specifies the variables (for example, interface status and
CPU usage) maintained by the SNMP agent for the SNMP manager to read and set.

MIB and view-based MIB access control
A MIB stores variables called "nodes" or "objects" in a tree hierarchy and identifies each node with a
unique OID. An OID is a dotted numeric string that uniquely identifies the path from the root node to a
leaf node. For example, object B in Figure 32 is u
ni
quely identified by the OID {1.2.1.1}.
