Order of Processing Timeout Values

Definitions:

• Session timeout: Period of  time (seconds) required for the application to time out due to inactivity.
• TCP Timeout (seconds): Timeout for terminating a TCP  application flow (1-604800 seconds).
• UDP Timeout (seconds): Timeout for terminating a UDP  application flow (1-604800 seconds).

There are application-specific timeout values defined in App Content and updates and system default timeout values based on protocol.

Application-specific values will take precedence if present as follows:

• For TCP, app-specific TCP timeout > app-specific timeout > TCP default timeout
  • CLI command to adjust the TCP default value: >set session timeout-tcp
• For UDP, app-specific UDP timeout > app-specific timeout > UDP default timeout
  • CLI command to adjust the UDP default value: >set session timeout-udp
• For ICMP, app-specific timeout > ICMP default timeout (timeout-icmp in CLI)
  • CLI command to adjust the ICMP default value: >set session timeout-icmp
• For all other IP protocols, app-specific timeout > other-IP default timeout
  • CLI command to adjust the app-specific value: >set session timeout-default

Default Timeout Values: a

Session timeout

• TCP default timeout: 3600 seconds
• TCP session timeout before 3-way handshaking: 5  seconds
• TCP session timeout after FIN/RST: 30  seconds
• UDP default timeout: 30 seconds
• ICMP default timeout: 6 seconds
• other IP default timeout: 30 seconds

Session timeout in discard state:

• TCP: 90 seconds
• UDP: 60 seconds
• other IP protocols: 60 seconds
