Monitoring the Evolved Packet Data Gateway

This chapter provides information for monitoring the status and performance of the ePDG (evolved Packet Data Gateway) using the show commands found in the CLI (Command Line Interface). These command have many related keywords that allow them to provide useful information on all aspects of the system ranging from current software configuration through call activity and status.

The selection of show commands listed in this chapter is intended to provided the most useful and in-depth information for monitoring the system. For additional information on these and other show commands and keywords, refer to the eHRPD/LTE Command Line Interface Reference.

The system also supports the sending of SNMP (Simple Network Management Protocol) traps that indicate status and alarm conditions. See the SNMP MIB Reference for a detailed listing of these traps.

Monitoring ePDG Status and Performance

The following table contains the CLI commands used to monitor the status of the ePDG features and functions. Output descriptions for most of the commands are located in the Statistics and Counters Reference.

Clearing Statistics and Counters

It may be necessary to periodically clear statistics and counters in order to gather new information. The system provides the ability to clear statistics and counters based on their grouping.

Statistics and counters can be cleared using the CLI clear command. You can also use specific command options such as clear epdg-service statistics dns-stats . Refer to the eHRPD/LTE Command Line Interface Reference for detailed information on using this command.
