is measured in seconds and can be configured to any integer value between 1 and 20.
Usage
This command is used in conjunction with the
command to control the
retransmission of GTP control packets when no response is received from an SGSN.
If no response is received from the SGSN prior to the expiration of the timeout value, the GTP control
packets are re-sent by the GGSN. This process occurs as many times as allowed by the configuration of the
max-retransmissions command.
If the max-retransmissions value is exceeded within the retransmission-timeout period, the GGSN records a
―Path Failure‖ for that SGSN and releases all PDP contexts associated with it.
