Test Commands
In the event that an issue was discovered with an installed application or line card, depending on the severity, it may be
necessary to take corrective action.
necessary to take corrective action.
The system provides several redundancy and fail-over mechanisms to address issues with application and line cards in
order to minimize system downtime and data loss. These mechanisms are described in the sections that follow.

Using the GTPU Test Echo Command
This command tests the HeNB-GW’s ability to exchange GPRS Tunneling Protocol user plane (GTP-U) packets with
the specified peer nodes which can be useful in troubleshooting and/or monitoring.
the specified peer nodes which can be useful in troubleshooting and/or monitoring.
The test is performed by the system sending GTP-U echo request messages to the specified node(s) and waiting for a
response.

Important:
This command must be executed from within the context in which at least one HeNB-GW
service is configured.
The command has the following syntax:

Using the SNMP TRAP command for debugging
Once the thresholds are configured, then notifications get generated on reaching the limit in the configured interval and
are then shown in the SNMP trap.

The SNMP traps for HeNB-GE service can be configured using the following command syntax:
snmp trap enable { ThreshHENBGWHenbSessions | ThreshHENBGWPagingMessages |
ThreshHENBGWUeSessions } target trap_target
ThreshHENBGWUeSessions } target trap_target
