Remote host manual TCP connection check

A manual TCP connection check can be performed for each remote host configured for a raw socket IP transport subservice. When executed by an operator, the TCP connection check attempts to establish a TCP session toward the configured remote host. Only one TCP connection check attempt is made, with a fixed timeout of 5 seconds. If the attempt is successful, the session is torn down immediately without data being sent.

The TCP connection check is initiated in the CLI using the tools>perform>service>ip-transport>remote-host>check-tcp command. The result is displayed in the CLI using the tools>dump>service>ip-transport>remote-host>check-tcp command. Equivalent management is available via SNMP.

If a TCP connection to a remote host already exists because of serial traffic being transmitted, the check returns "successful" without impacting the existing TCP connection.
