Configuring the GTP Timers

This section describes how to configure the GTP timers.

The GTP timer configuration is implemented when a signaling message or triggered message (for which a reply is expected) is lost as it did not get a response before the T3-RESPONSE timer expired. After the T3-RESPONSE timer expires, the message corresponding to the T3-RESPONSE timer is retransmitted if the total number of retry attempts is less than the N3‑REQUESTS times.

configure 
  endpoint gtp 
     retransmission { max-retry retry_count | timeout timeout_duration }  
     end 

NOTES:

  • endpoint gtp — Enters the GTP retransmission configuration.

  • max-retry retry_count — Specifies the number of times the signalling message request to SMF must be reattempted. The accepted range is 0–5. Default range is 3. When the retry_count is set to "0", the retransmission feature is disabled.

  • timeout timeout_duration — Configures the interval of time (in milliseconds) after which the GTP retransmission request is reattempted. The accepted range is 0–10. Default range is 2. When the timeout_duration is set to "0", the retransmission feature is disabled.
