Feature Configuration

SMF optimizes the roaming peers using the following configuration:

config 
   instance instance-id gr_instance_id 
   endpoint gtp 
      interface { s2b | s5 | s5e | s8 | s11 } 
      echo interval echo_interval 
      echo retransmission-timeout retransmission_timeout_value 
      echo max-retransmissions max_retry_count 
      end 

NOTES:

  • interval echo_interval —The echo interval range is <300-3600> seconds. The default value is Default 300 seconds. Configuring echo interval with 0 second disables the outbound echo. This change is applicable irrespective of the interface type. For other interfaces like s2b, s5, s5e, and s11, the echo interval range is <60-3600> seconds.

  • retransmission-timeout retransmission_timeout_value —The retransmission timeout range for the S8 interface is <60-180> seconds. The default value is 60 seconds. For other interfaces like s2b, s5, s5e, and s11, the retransmission-timeout range is <1-20> seconds.

  • max-retransmissions max_retry_count —The value range of maximum number of retries for GTP Echo Request is 0-4. The default value is 4. For other interfaces like s2b, s5, s5e, and s11, the max-retransmissions range is <0-10>.

Note

These parameters are applicable only for the S8 interface. For other interfaces, the existing configuration is applicable.
