This chapter discusses SNMP (Simple Network Management Protocol) for network management and
monitoring.
8.1 About SNMP
Simple Network Management Protocol is a protocol used for exchanging management information between
network devices. SNMP is a member of TCP/IP protocol suite. Your VES-1000 Series switch supports SNMP
agent functionality, which allows a manager station to manage and monitor the VES-1000 Series switch through
the network. The VES-1000 Series switch supports SNMP version one (SNMPv1). The next figure illustrates an
SNMP management operation. SNMP is only available if TCP/IP is configured.
Figure 8-1 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 device (the VES-1000 Series switch). An
agent translates the local management information from the managed device 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 device. Examples of variables include such as number of packets received, node port status etc.
