▀ Test Commands

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.
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 HNB-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 test is performed by the system sending GTP-U echo request messages to the specified node(s) and waiting for a
response.
Important:
service is configured.
The command has the following syntax:
gtpu test echo src-address src_ip_address{ all | sgsn-address ip_address }
Keyword/Variable
src-address
src_ip_address
all
The following figure displays a sample of this command's output showing a successful GTPU echo-test from an HNB-
GW service bound to address 192.168.157.32 to an SGSN with an address of 192.168.157.2.

Using the GTPv0 Test Echo Command

This command tests the HNB-GW's ability to exchange GPRS Tunneling Protocol version 0 (GTPv0) packets with the
specified SGSNs which can be useful troubleshooting and/or monitoring.
The test is performed by the system sending GTPv0 echo request messages to the specified SGSN(s) and waiting for a
response.

Specifies the IP address of an interface configured on the system.
NOTE: The IP address of the system's interface must be bound to a configured HNB-GW service
prior to executing this command.
Specifies that GTP-U echo requests will be sent to all Nodes that currently have sessions with the
HNB-GW service.
