PFCP Agent Configuration Issues

[David Lake]

Hello

 

I am trying to understand the PFCP Agent configuration.  I have deployed the EdgeCore switches, Stratum and ONOS successfully using the Helm charts.

 

The PFCP-Agent is running but constantly restarting.

 

In the configuration for the PFCP Agent I see this:

 

/tmp/conf # more upf.json

{"cpiface":{"dnn":"internet","hostname":"pfcp-agent.k8s.intra","http_port":"8080","ue_ip_pool":"10.250.0.0/24"},"enable_p4rt":true,"log_level":"info","p4rtciface":{"access_ip":"172.17.0.1/32","p4rtc_port":"51001","p4rtc_server":"sdfabric-onos-classic-hs","slice_id":0}}

 

Ifconfig for the pod shows this:

 

eth0      Link encap:Ethernet  HWaddr EA:EB:EA:26:2D:A9 

          inet addr:10.244.2.81  Bcast:10.244.2.255  Mask:255.255.255.0

          UP BROADCAST RUNNING MULTICAST  MTU:1450  Metric:1

          RX packets:168378289 errors:0 dropped:0 overruns:0 frame:0

          TX packets:169203416 errors:0 dropped:14 overruns:0 carrier:0

          collisions:0 txqueuelen:0

          RX bytes:11320651571 (10.5 GiB)  TX bytes:11324110116 (10.5 GiB)

 

The hosts file on the pfcp-agent pod shows:

 

                10.244.2.81     sdfabric-pfcp-agent-0.pfcp-headless.sdfabric.svc.cluster.local  sdfabric-pfcp-agent-0

 

I don’t understand what the ‘pfcp-agent.k8s.intra’ is in the upf.json file.   The IP address allocated to this in CoreDNS (10.109.250.119 where there is an entre for pfcp-agent.k8s.intra) is not reachable anywhere.

 

When I configure the SMF in my 5G Control Plane, which IP address is the PFCP interface?

 

Thank you

David
