GTP Inspection
Verifying and Monitoring GTP Inspection
To display the GTP configuration, enter the show service-policy inspect gtp command in privileged
EXEC mode.
Use the show service-policy inspect gtp statistics command to show the statistics for GTP inspection.
The following is sample output from the show service-policy inspect gtp statistics command:
hostname# show service-policy inspect gtp statistics

The following is sample GSN output from the show service-policy inspect gtp statistics gsn command:
hostname# show service-policy inspect gtp statistics gsn 10.9.9.9
1 in use, 1 most used, timeout 0:00:00

Use the show service-policy inspect gtp pdp-context command to display PDP context-related
information. For example:
hostname# show service-policy inspect gtp pdp-context detail
1 in use, 1 most used, timeout 0:00:00

The PDP context is identified by the tunnel ID, which is a combination of the values for IMSI and
NSAPI. A GTP tunnel is defined by two associated PDP contexts in different GSN nodes and is
identified with a Tunnel ID. A GTP tunnel is necessary to forward packets between an external packet
data network and a MS user.
