The TCP Applications Flags Enhancement feature enables you to display additional flags with reference 
to TCP applications. There are two types of flags: status and option. The status flags indicate the status 
of TCP connections, such as retransmission timeouts, application closed, and synchronized (SYNC) 
handshakes for listen. The additional flags indicate the state of set options, such as whether or not a 
virtual private network (VPN) routing and forwarding (VRF) instance is set, whether or not a user is idle, 
and whether or not a keepalive timer is running.

Configuration information is included in the “Configuring TCP” module of the Cisco IOS IP Application
