Chapter 5. Network Management Configuration
Network Management Configuration 5.1
5.1.1 SNMP Configuration
5.1.2 Overview
The SNMP system includes the following 3 parts:
SNMP management server (NMS)
SNMP agent (agent)
MIB
SNMP is a protocol for the application layer.It provides the format for the packets which are transmitted
between NMS and agent.
SNMP management server is a part of the network management system, such as CiscoWorks.
SNMP agent includes the MIB variable and the SNMP management server can be used to browse or change
these variables’ values.The management server can get the values from the agent or save these variables in
the agent.The agent collects data from MIB.MIB is the database of equipment parameters and network data.
5.1.3 SNMP Notification
When a special event occurs, the system will send an inform to the SNMP management server.For example,
when the agent system runs into a incorrect condition, it will send a message to the management server.
The SNMP notification can be sent as a trap or a inform request.Because the receiver receives a trap and
does not send any response, the transmitter hence cannot confirm whether the trap is received. In this way,
the trap is unreliable.Comparatively, the SNMP management server uses SNMP to respond PDU, which is
acted as a response of this message.If the management server does not receive the inform request, it will not
transmit a response.If the transmitter does not receives the response, it will transmit the inform request
again.In this way, the inform has more chance to arrive the planned destination.
