Configuring the Heartbeat at the Interface Level

To configure the Heartbeat at the interface-level, use the following sample configuration:

config 
    instance instance-id gr_instance_id 
        endpoint pfcp 
            interface { n4 | sxa } 
                heartbeat 
                    interval interval 
                        max-retransmissions max_retry_count 
                        retransmission-timeout retry_interval_count 
                        end 

NOTES:

  • instance instance-id gr_instance_id —Specify the GR instance ID.

  • endpoint pfcp —Specifies the endpoint configuration mode.

  • interface { n4 | sxa } —Configures the N4 or Sxa interface over which the Heartbeat messages get exchanged between the SMF and the UPF.

  • Heartbeat —Specifies the Heartbeat configuration.

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

    Note

    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. Must be in the range of 0–10. The default value is 3.

  • retransmission-timeout retry_interval_count —Specify the Heartbeat retransmission timeout in seconds. Must be in the range of 1–20. The default value is 5.
