Information About SNMP
The Simple Network Management Protocol (SNMP) is an application-layer protocol that provides a message
format for communication between SNMP managers and agents. SNMP provides a standardized framework
and a common language used for the monitoring and management of devices in a network.
SNMP Functional Overview
The SNMP framework consists of three parts:
• An SNMP manager—The system used to control and monitor the activities of network devices using
SNMP.
• An SNMP agent—The software component within the managed device that maintains the data for the
device and reports these data, as needed, to managing systems. The Cisco Nexus device supports the
agent and MIB. To enable the SNMP agent, you must define the relationship between the manager and
the agent.
• A managed information base (MIB)—The collection of managed objects on the SNMP agent
Cisco NX-OS does not support SNMP sets for Ethernet MIBs.
Note
The Cisco Nexus device supports SNMPv1, SNMPv2c, and SNMPv3. Both SNMPv1 and SNMPv2c use a
community-based form of security.
