▀ ip local-port
▄ Cisco ASR 5000 Series Command Line Interface Reference
OL-22948-01
ip local-port
Configures the local User Datagram Protocol (UDP) port for the Gn interfaces‘ GTPC socket for GTPv1.
Product
GGSN
Privilege
Security Administrator, Administrator
Syntax
Default: 2123
Specifies the UDP port number for GTPv1 GTPC sockets.
Specifies the UDP port number for GTPv1 GTPC sockets.
can be configured to any integer value between 1 and 65535.
Usage
By default, the GGSN service attempts to use GTPv1 when communicating with SGSNs. This parameter
configures the UDP port over which the GTP control (GTPC) sockets are sent.
If an SGSN only supports GTPv0, the GGSN service automatically switches to GTPv0 when communicating
with this SGSN. In the scenario, the GGSN service communicates with the SGSN on UDP port 3386 and
does not have a GTPC socket.

Important:
The UDP port setting on the SGSN must match the local-port setting for the GGSN service on the
system in order for the two devices to communicate.
Example
The following command configures the GGSN service to use UDP port 2500 for exchanging GTPC sockets with
SGSNs when using GTPv1:
