Configuring the SRC 3GPP Gateway Gx Interface (SRC CLI)

Note: The SRC 3GPP gateway uses its own Diameter stack, which is configured under the [edit slot 0 gw-3gpp gx] hierarchy. It does not use the Diameter stack configured under the [edit system diameter] hierarchy; this Diameter stack is used for SAE and router communication.

1. From configuration mode, access the statement that configures the SRC 3GPP gateway Gx interface.
   user@host# edit slot 0 gw-3gpp gx
2. (Optional) Specify the Diameter identifier for the remote endpoint, which is the destination of the Diameter message. The Destination-Host AVP (AVP Code 293) is of the DiameterIdentity type and is present in all Diameter messages.
   [edit slot 0 gw-3gpp gx]user@host# set destination-host destination-host
3. Specify the Diameter identifier for the realm of the remote endpoint, which is the destination of the Diameter message. The Destination-Realm AVP (AVP Code 283) is of the DiameterIdentity type and is present in all Diameter messages.
   [edit slot 0 gw-3gpp gx]user@host# set destination-realm destination-realm
4. Specify the list of remote Diameter peers (PCRFs) that connect to the SRC 3GPP gateway over the Gx interface.
   [edit slot 0 gw-3gpp gx]user@host# set diameter-peer [diameter-peer....]

   Each Diameter peer you specify must be previously configured under the [edit shared network diameter peer] hierarchy.

5. (Optional) Specify the protocol for the transport connection.
   [edit slot 0 gw-3gpp gx]user@host# set protocol [(tcp | sctp)...]
6. (Optional) Specify the port to use for incoming connections.
   [edit slot 0 gw-3gpp gx]user@host# set port port
7. Specify the local address of the peer.
   [edit slot 0 gw-3gpp gx]user@host# set address address
8. Specify the Diameter identifier for the local endpoint that is the originator of the Diameter message.
   [edit slot 0 gw-3gpp gx]user@host# set origin-host origin-host
9. Specify the Diameter identifier for the realm of the local endpoint that is the originator of the Diameter message.
   [edit slot 0 gw-3gpp gx]user@host# set origin-realm origin-realm
10. (Optional) Verify your configuration.

    [edit slot 0 gw-3gpp gx] 
    user@host# show 
    address 10.10.10.10;
    destination-host testpcrf;
    destination-realm englab.juniper.net;
    diameter-peer [ primary-pcrf secondary-pcrf ];
    origin-host duke;
    origin-realm example;
    port 3868;
    protocol tcp;
    }
