RMON Overview 81

Required if traps are to be sent — the IP address of the interface ethernet 0 is the source address of the traps, and the address of the NMS is the destination address.

II. Networking Diagram

Refer to the networking diagram of Example 1.

III. Configuration Procedure

1 Enable the router to support SNMP and select an SNMP version.

[Router] snmp-agent

2 Set SNMP groups, users and views.

[Router] snmp-agent mib-view

included write_view subtree 1.3.6.1.5

[Router] snmp-agent mib-view

excluded notify_view subtree 1.3.6.2

3 Configure information of equipment administrator

[Router] snmp-agent sys-info contact Mr.Wang-Tel:3306

[Router] snmp-agent sys-info location telephone-closet,3rd-floor

4 Configure the router to send Traps to the host whose IP address is

 

129.102.149.23.

 

[Router] snmp-agent trap enable

 

[Router] snmp-agent target-host trap address 129.102.149.23

 

securityname user_notify parameters v3 auth

 

[Router] snmp-agent trap source ethernet 0

 

5 Configure an IP address for the Ethernet interface ethernet 0

 

[Router] interface ethernet 0

 

[Router-Ethernet0]ip address 129.102.0.1 255.255.0.0

 

 

RMON Overview

RMON (Remote Monitor) is a MIB defined by IETF and is the most important

 

enhancement for the MIB II standard. It mainly monitors the data flow in a

 

network segment or on the entire network. It is implemented on the basis of the

 

SNMP architecture (one of its strengths), including NMS and Agent running on

 

network equipment.

 

RMON Agent performs statistics of diversified flow information on the network

 

segments connected to the ports, such as the total messages on a network

 

segment within a certain period or the total of correct messages sent to a host. It

 

enables SNMP to monitor remote network devices more efficiently and more

 

actively and provides an efficient method to monitor sub-network running. This

 

method can help reduce communication flows between the NMS and the Agent,
