 ## Parameters
 
-* `protocol` \[enum: `tcp`/`udp`/`tls`\]
+### Protocol

+The protocol is specified as the argument of `<transport>` section.

+| :--- | :--- | :--- | :--- |
+| integer | 0 | tcp, tls | 1.14.6 |
+
+The timeout \(seconds\) to set `SO_LINGER`.
+
+The default value `0` is to send RST rather than FIN to avoid lots of connections sitting in TIME_WAIT on closing.
+
+You can set positive value to send FIN on closing.

+{% hint style='info' %}
+On Windows, Fluentd sends FIN without depending on this setting.
