SGTP Service Configuration Mode Commands
▀ gn-delay-monitoring
▄ Command Line Interface Reference, StarOS Release 17
8574
Important:
The value for this parameter should be less than the value set for the
retransmission-timeout
parameter of the
gtpc
command, also in this configuration mode.
Usage
With this command, the SGSN can monitor the control plane packet delay for GTP-C signaling messages on
the SGSN’s Gn/Gp interface towards the GGSN. If the delay crosses this configurable threshold, an alarm
will be generated to prompt the operator.
A delay trap is generated when the GGSN response to an ECHO message request is delayed more than a
configured amount of time and for a configured number of consecutive responses. When this occurs, the
GGSN will be flagged as experiencing delay.
A clear delay trap is generated when successive ECHO Response (number of successive responses to detect a
delay clearance is configurable), are received from a GGSN previously flagged as experiencing delay.
This functionality can assist with network maintenance, troubleshooting, and early fault discovery.

Enable Gn/Gp monitoring for GTP-C packets that arrive from the GGSN with a delay greater than
5
