Monitoring with Cisco IOS Software

SNMP and the CiscoWorks2000 Interface

Using SNMP, CiscoWorks2000 retrieves CDP information by polling

Cisco CallManager. After the discovery process is completed, a topology map reveals all the Cisco CallManager installations in the network.

CiscoWorks2000 also polls other MIB tables in the CISCO-CCM-MIB to gather information required by other components, such as User Tracking (refer to the CiscoWorks2000 Campus Manager online documentation). CiscoWorks2000 periodically polls these agents to get additional updated information.

Note For examples of how to use CiscoWorks2000 to troubleshoot network problems, see Chapter 4, “System Troubleshooting Guidelines.”

Monitoring with Cisco IOS Software

This section describes proven strategies to help you monitor your network.

Evaluating System Performance

Collecting, analyzing, and archiving system performance data is important in understanding how well your system is meeting your organization’s needs. Important things to monitor are the behavior of network applications and protocols and the response time of individual devices such as MRP cards and Catalyst 3524-PWR XL switches.

Common ways to monitor system performance include the following:

•Evaluating Reachability and Response Times

•Evaluating Traffic Loads
