TCP Application Flags Enhancement - New Socket Options

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.
