Syntax
retransmission-timeout-ms retransmit_time
default retransmission-timeout-ms
default
Configures the default time interval that must pass without an SGSN response before the GGSN service
retransmits GTP control packets.
retransmits GTP control packets.
retransmit_time
Default: 5000
Specifies the amount of time that must pass without an SGSN response before the GGSN service retransmits
GTP control packets.
Specifies the amount of time that must pass without an SGSN response before the GGSN service retransmits
GTP control packets.
retransmit_time
is measured in milliseconds and can be configured to an integer from 1000 through
20000, with a granularity of 100 milliseconds.
Usage
This command is used in conjunction with the
max-retransmissions
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.

Important:
This retransmission timeout configuration in not applicable for Echo Requests message
retransmission. Echo are sent/retransmitted every echo interval, which can be configured separately.
