Using StarOS Diagnostic Utilities 
StarOS 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:
  Only an administrator with Operator or higher privilege can run the diagnostic utilities described in 
this section. 
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 via the VPC-VSM instance. 
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. It is highly 
recommended that logging be enabled on your terminal client in order to capture all of the information that is generated. 
The protocol monitor is also used to capture packets over a particular interface. 
Follow the instructions below to invoke and configure the protocol monitoring tool. 
Step 1 
Invoke the protocol monitor from the Exec mode by entering the monitor protocol command. 
An output listing all the currently available protocols, each with an assigned number, is displayed. 
Step 2 
Choose the protocol that you wish to monitor by entering the associated number at the Select: prompt. A right arrow ( > 
) appears next to the protocol you selected. 
Step 3 
Repeat step 2 as needed to choose multiple protocols. 
Step 4 
Press 
B
 to begin the protocol monitor.
