H.323 Inspection - Cisco PIX 500 Series Configuration Manual

Chapter 25 Configuring Application Layer Protocol Inspection
The following is sample GSN output from the show service-policy inspect gtp statistics gsn command:
hostname# show service-policy inspect gtp statistics gsn 9.9.9.9
1 in use, 1 most used, timeout 0:00:00
GTP GSN Statistics for 9.9.9.9, Idle 0:00:00, restart counter 0
Use the show service-policy inspect gtp pdp-context command to display PDP context-related
information. The following is sample output from the show service-policy inspect gtp pdp-context
command:
hostname# show service-policy inspect gtp pdp-context detail
1 in use, 1 most used, timeout 0:00:00
Version TID
v1
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.
You can use the vertical bar (|) to filter the display, as in the following example:
hostname# show service-policy gtp statistics
