SNMP Configuration 23-1
Chapter 23
SNMP Configuration
This chapter discusses SNMP (Simple Network Management Protocol) for network management and
monitoring.
23.1 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 VLC1012 supports SNMP agent
functionality, which allows a manager station to manage and monitor the VLC1012 through the network. The
VLC1012 supports SNMP version one (SNMPv1). The next figure illustrates an SNMP management operation.
SNMP is only available if TCP/IP is configured.
Figure 23-1 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 VLC1012). 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.
