can be configured to any integer value between 0 and 15.
Usage
This command is used in conjunction with the timeout command to control the retransmission of GTP
control packets when no response is received from an SGSN. It is equivalent to the N3-REQUESTS
parameter discussed in 3GPP TS 29.060.
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 this
command.
If the max-retransmissions value is exceeded, the GGSN records a ―Path Failure‖ for that SGSN and releases
all PDP contexts associated with it.
