Using the System Diagnostic Utilities

The system provides protocol monitor and test utilities that are useful when troubleshooting or verifying

configurations. The information generated by these utilities can help identify the root cause of a software or

network configuration issue.

This section describes how to use these utilities.

Important

Using the Monitor Utility

For troubleshooting purposes, the system provides a protocol monitoring utility. This tool displays protocol

information for a particular subscriber session or for every session being processed.

Caution

The monitor tool may cause session processing delays and/or data loss. Therefore, it should be used only

when troubleshooting.

Using the Protocol Monitor

The protocol monitor displays information for every session that is currently being processed. Depending on

the number of protocols monitored, and the number of sessions in progress, a significant amount of data is

generated. You should enable logging on your terminal client to capture all of the information that is generated.

Follow the instructions in this section to invoke and configure the protocol monitoring tool.

Step 1

Invoke the protocol monitor from the Exec mode by entering the monitor protocol command.
