How to check if an active TCP connection is using the TCP keepalive option and to list the associated value (Doc ID 2015135.1)

Last updated on SEPTEMBER 29, 2020

Applies to:

Solaris Operating System - Version 11 11/11 to 11.2 [Release 11.0]
Information in this document applies to any platform.


This document describes how to check an active TCP connection to see whether that connection is using the TCP keepalive option. If the option is active we also want to check the used value.

These steps are specific to Solaris 11 as Solaris 10 and older is using a different TCP/IP stack where these checks are not available yet.
