Diagnose firewall gtp tunnel list command

The diagnose fiewall gtp tunnel list command displays information about all of the active GTP tunnels, for example:

diagnose firewall gtp tunnel list
list gtp tunnels

Notes about the command output

Index=00000062 means 6x16 + 2 = 98 decimal as shown in GTP Log.

downlink cfteid, addr=172.30.111.2 is the source of the GTP-C create_session_request. The field inf_type=s11 indicates MME.

uplink cfteid, addr=172.30.111.4 is the source of the GTP-C create_session_response. The field intf_type=s11/s4 indicates SGW.

For the bearers, GTP-U traffic (information as received from the SGW in the Create_Session_Response) includes the following fields:

  • addr=172.30.111.6 GTP-U from eNodeB to SGW (S1-U).

  • addr=172.30.111.7 GTP-U from PGW to SGW (S5-U).
