The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter provides information and instructions for using the system command line interface (CLI) for troubleshooting issues that may arise during service operation.
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.
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.
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.
This command must be executed from within the context in which at least one HeNB-GW service is configured.
gtpu test echo gtpu-service gtpu_svc_name { all | peer-address ip_addr } gtpu-version { 0 | 1 }
| Keyword/Variable | Description |
|---|---|
| gtpu-service gtpu_svc_name | Specifies the GTP-U service configured on the system and associated with the HeNB-GW Network service. |
| peer-address ip_addr | Specifies
the IP address of the HeNB node. NOTE: The IP address of the system's interface must be bound to a configured HeNB-GW service prior to executing this command. |
| all | Specifies that GTP-U echo requests will be sent to all Nodes that currently have sessions with the HeNB-GW service. |
| gtpu-version { 0 | 1 } | Specifies the the GTPU version of peer node. This is optional; if provided and the peer version is not known, the user supplied version is used while sending echo. |
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.
snmp trap enable { ThreshHENBGWHenbSessions | ThreshHENBGWPagingMessages | ThreshHENBGWUeSessions } target trap_target
| Keyword/Variable | Description |
|---|---|
| ThreshHENBGWHenbSessions | Enables the threshold configuration for HeNB-GW HeNB sessions. |
| ThreshHENBGWPagingMessages | Enables the threshold configuration for HeNB-GW paging messages. |
| ThreshHENBGWUeSessions | Enables the threshold configuration for HeNB-GW UE sessions. |
| trap_target | Specifies that these trap(s) should be sent to this trap target. |
The show resources session command is ideal for debugging the license-controlled number of HeNBs and subscribers/UEsconnecting to the HeNB-GW.
show resources session
In
case, the number of sessions are within the acceptable limits, the
output of the above command looks as the following sample (only
HeNB-GW related sessions have been shown):HENBGW Service: In Use : 1161 Max Used : 1161 ( Monday May 06 05:22:00 IST 2013 ) Limit : 2000 License Status : Within Acceptable Limits HENBGW UE Service: In Use : 1700 Max Used : 1700 ( Monday May 06 05:20:10 IST 2013 ) Limit : 2000 License Status : Within Acceptable Limits
In case, the number of sessions are over the license capacity, the output of this command looks as the following sample (only HeNB-GW related sessions have been shown):
HENBGW Service: In Use : 2000 Max Used : 2000 ( Monday May 06 05:22:00 IST 2013 ) Limit : 2000 License Status : Over License Capacity (Rejecting Excess Calls) HENBGW UE Service: In Use : 2000 Max Used : 2000 ( Monday May 06 05:20:10 IST 2013 ) Limit : 2000 License Status : Over License Capacity (Rejecting Excess Calls)
