Configuring SNMP
SNMP overview
Simple Network Management Protocol (SNMP) is an Internet standard protocol widely used for a
management station to access and manage the devices on a network. SNMP shields the physical
differences between various devices and realizes automatic management of products from different
manufacturers.
An SNMP enabled network comprises the network management system (NMS) and agents.
The NMS manages agents by exchanging management information through SNMP. The NMS and
managed agents must use the same SNMP version to communicate with each other.
SNMP agents support SNMPv1, SNMPv2c, and SNMPv3.
• SNMPv1—Uses community names for authentication. Like the password, a community name is
used to restrict the communication between the NMS and the Agent. To access an SNMP agent, an
NMS must use the same community name as the one that is set on the SNMP agent. If the
community name used by the NMS is different from that set on the agent, the NMS cannot establish
an SNMP session to access the agent or receive traps and notifications from the agent.
• SNMPv2c—Uses community names for authentication. SNMPv2c is compatible with SNMPv1 and
supports more operation modes, data types, and error codes.
• SNMPv3—Uses a user-based security model (USM) to secure SNMP communication. You can
configure authentication and privacy mechanisms to authenticate and encrypt SNMP packets for
integrity, authenticity, and confidentiality.

SNMP configuration task list
SNMPv3 differs from SNMPv1 and SNMPv2c in configurations. The following describes their
configuration procedures separately.
SNMPv1 or SNMPv2c configuration task list
Perform the tasks in Table 51 to configure SNMPv1 or SNMPv2c.
Table 51 SNMPv1 or SNMPv2c configuration task list
Task Remarks
Enabling SNMP agent
Required.
The SNMP agent function is disabled by default.
IMPORTANT:
If SNMP agent is disabled, all SNMP agent-related configurations are
removed.
