   show security gtp profile (profile-name | all)   

Description

Use this command to display the GTP configuration. IP addresses in GPRS tunneling protocol (GTP) message on Gp or the S8 interface are validated with the configured IP group list to prevent attacks. The GTP firewall determines the IP addresses in GTP messages and matches with the configured IP group list. Based on the match criteria, valid GTP messages are forwarded to Packet and Forwarding Engine, and invalid GTP messages are dropped.

From Junos OS Release 20.4R1 onwards, show security gprs gtp configuration is replaced by show security gtp profile <profile_name>. The identifier option is replaced by profile-name in Junos OS Release 20.4R1.

Options

profile-name —Displays specific GTP profile.
all —Displays all the GTP profile list.
