SNMP Basics

SNMP Basics

The Simple Network Management Protocol (SNMP) facilitates the exchange of management information among network devices. SNMP is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP enables you to manage network performance, find and solve network problems, and plan for network growth.

SNMP Components

An SNMP-managed network consists of three key components: managed devices, agents, and network management systems (NMSs).

•A managed device is a network node that contains an SNMP agent and resides on a managed network. Managed devices collect and store management information and make it available using SNMP. The Cisco ICS 7750 includes the following managed devices:

–System processing engine (SPE) cards

–Analog station interface (ASI) cards

–Multiservice route processor (MRP) cards

–System switch processor (SSP) card

–Catalyst 3524-PWR XL switches

•An agent is network-management software that resides on a managed device. An agent has local knowledge of management information and translates it into a form compatible with SNMP. The agent on the Cisco ICS 7750 is located on the SPE running System Manager.
