32.8.1 About SNMP
Simple Network Management Protocol (SNMP) is an application layer protocol used to manage and
monitor TCP/IP-based devices. SNMP is used to exchange management information between the
network management system (NMS) and a network element (NE). A manager station can manage and
monitor the Switch through the network through SNMP version 1 (SNMPv1), SNMP version 2c or SNMP
version 3. The next figure illustrates an SNMP management operation. SNMP is only available if TCP/IP is
configured.

SNMP Management Model
An SNMP managed network consists of two main components: agents and a manager.
An agent is a management software module that resides in a managed Switch (the Switch). An agent
translates the local management information from the managed Switch into a form compatible with
SNMP. The manager is the console through which network administrators perform network management
functions. It executes applications that control and monitor managed devices.
