4.1 SNMP
Simple Network Management Protocol is a protocol used for exchanging management information
between network switches. SNMP is a member of TCP/IP protocol suite. A manager station can
manage and monitor the switch through the network via SNMP version 2c. 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 (your Ethernet
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.
The managed devices contain object variables/managed objects that define each piece of
information to be collected about a switch. Examples of variables include such as number of packets
received, node port status etc. A Management Information Base (MIB) is a collection of managed
objects. SNMP allows a manager and agents to communicate for the purpose of accessing these
objects.
