Configuring the Heartbeat Parameters for UPF

This section describes how to configure the heartbeat feature for UPF.

To configure the heartbeat feature for UPF at the interface-level, use the following configuration:

config 

      endpoint pfcp 
         interface { n4 | sxa } 
            heartbeat 
               interval interval 
               max-retransmissions max_retry_count 
               retransmission-timeout retry_interval 
               end 

NOTES:

  • endpoint pfcp : Enters the endpoint configuration mode.

  • interface : Configures the N4 or Sxa interface over which the heartbeat messages are exchanged between SMF and UPF.

  • heartbeat : Enters the heartbeat configuration.

  • interval interval : Specify the heartbeat interval in seconds. The accepted range is 60–360. The default value is 60 seconds.

    Setting the interval to "0" disables the heartbeat feature.

  • max-retransmissions max_retry_count : Specify the maximum retries for the Packet Forwarding Control Protocol (PFCP) heartbeat request. The accepted range is 0–10. The default value is 3.

  • retransmission-timeout retry_interval : Specify the heartbeat retransmission timeout in seconds. The accepted range is 1–20. The default value is 5.
