retransmission-timeout seconds
Default: 5
Configures the retransmission timeout for GTPU packets in seconds.
Configures the retransmission timeout for GTPU packets in seconds.

: Must be an integer from 1 through 20.
sync-echo-with-peer
This keyword is applicable to the SGSN only.
This keyword enables the SGSN to synchronize path management procedures with the peer after a GTP
service restart recovery.
After GTP service recovery, the SGSN restarts the timers for GTP echo transmission, hence a drift in echo
request transmission time (from the pre-recovery time) can occur causing the SGSN to be out of sync with the
peer. By using this keyword, when the SGSN receives the first Echo Request (GTPC or GTPU) from the peer
after the GTP service restart, in addition to replying with an ECHO Response, the SGSN transmits an ECHO
Request to the peer and the SGSN restarts the timers associated with the path management procedures. This
causes the path management procedure at SGSN to synchronize with the peer node.
Default: Enabled

Usage
Use this command to configure GTP-U parameters for the Iu-PS interface.
Example
The following command binds the IP address
192.168.0.10
to the Iu-PS interface for communication with
the UTRAN:
gtpu bind address 192.168.0.10
