tcpMaxConn This field displays the maximum number of TCP connections the Switch
can support. If the maximum number is dynamic, this field displays -1.
tcpActiveOpens This field displays the number of times TCP connections have made a
direct transition to the SYN-SENT state from the CLOSED state.
tcpPassiveOpens This field displays the number of times TCP connections have made a
direct transition to the SYN-RCVD state from the LISTEN state.
tcpAttemptFails This field displays the number of times TCP connections have made a
direct transition to the CLOSED state from either the SYN-SENT state or
the SYN-RCVD state, plus the number of times TCP connections have
made a direct transition to the LISTEN state from the SYN-RCVD state.
tcpEstabResets This field displays the number of times TCP connections have made a
direct transition to the CLOSED state from either the ESTABLISHED state
or the CLOSE-WAIT state.
tcpCurrEstab This field displays the number of TCP connections for which the current
state is either ESTABLISHED or CLOSE-WAIT.
tcpInSegs This field displays the total number of segments received, including those
received in error. This count includes segments received on currently
established connections.
tcpOutSegs This field displays the total number of segments sent, including those on
current connections but excluding those containing only retransmitted
octets.
tcpRetransSegs This field displays the total number of TCP segments transmitted
containing one or more previously transmitted octets.
tcpInErrs This field displays the total number of segments received with error (for
example, bad TCP checksums).
tcpOutRsts This field displays the number of TCP segments sent containing the RST
flag.
This section displays the current TCP listeners.
&TCB This field displays the session ID.
Rcv-Q This field displays the items on the receive queue in this connection.
Snd-Q This field displays the sequence number of the first unacknowledged
segment on the send queue in this connection.
Rcv-Wnd This field displays the receiving window size in this connection. It
determines the amount of received data that can be buffered.
Snd-Wnd This field displays the sending window size in this connection. It is offered
by the remote device.
Local socket This field displays the local IP address and port number in this TCP
connection. In the case of a connection in the LISTEN state that is willing to
accept connections for any IP interface associated with the node, the value
is 0.0.0.0.
