Simple Network Management Protocol (SNMP) offers a framework to monitor network devices through TCP/IP protocol suite. It provides a set of basic operations in monitoring and maintaining the Internet and has the following characteristics:

l Automatic network management: SNMP enables network administrators to search and modify information, find and diagnose network problems, plan for network growth, and generate reports on network nodes.

l SNMP shields the physical differences between various devices and thus realizes automatic management of products from different manufacturers. Offering only the basic set of functions, SNMP makes the management tasks independent of both the physical features of the managed devices and the underlying networking technology. Thus, SNMP achieves effective management of devices from different manufacturers, especially in small, high-speed and low cost network environments.

Configuring SNMPv2c to Monitor and Manage a Switch

Network Diagram

Figure 1-1 Network diagram for configuring SNMPv2c to monitor and manage a switch

Networking and Configuration Requirements

l The Network Management Station (NMS) connects to the agent, a switch, through an Ethernet.

l The IP address of the NMS is 1.1.1.2/24.

l The IP address of VLAN interface on the switch is 1.1.1.1/24.

l NMS monitors and manages Agent using SNMPv2c. Agent reports errors or faults to the NMS.

l Configure SNMP NMS (refer to NMS manuals for detailed configurations)

#Select SNMPv2c; configure public as the read only community name, private as the read and write community name; specify 161 as the SNMP port number.

# In order to receive traps sent from Agent, set the number of inbound port for traps on the NMS to 5000, which is the same with that configured using the command line on Agent.

# Upon the above configurations, the NMS can monitor and manage the switch remotely; and the switch will send traps to the NMS in case of failures or errors.

Configuration Guidelines

Follow these guidelines when configuring SNMP logging:

1) The system information of the information center can be output to the terminal or to the log buffer. In this example, SNMP log is output to the terminal. For configuration of SNMP log output to other destinations, see the Information Center section in the Operation Manual of your product.

2) Successful output of logs to the terminal requires the Get and Set operations of NMS on Agent.

3) Logs occupy storage space of the device, thus affecting the performance of the device. Therefore, it is recommended to disable SNMP logging.

2 RMON Configuration Guide

RMON Overview

Remote Monitoring (RMON) is implemented based on SNMP and is fully compatible with the existing SNMP framework without the need of any modification on SNMP.

RMON provides an efficient means of monitoring subnets and allows SNMP to monitor remote network devices in a more proactive and effective way. It reduces traffic between NMS and agent, facilitating large network management.

Configuring RMON

Network Diagram

Figure 2-1 Network diagram for RMON

Networking and Configuration Requirements

Agent is connected to a configuration terminal through its console port and to a remote NMS across the Internet.

Create an entry in the RMON Ethernet statistics table to gather statistics on GigabitEthernet 1/0/1, and logging is enabled after received bytes exceed the specified threshold.
