DESCRIPTION
This field displays the algorithm used to determine the timeout value that is used for
retransmitting unacknowledged octets.
This field displays the minimum timeout (in milliseconds) permitted by a TCP
implementation for the retransmission timeout. More refined semantics for objects of
this type depend upon the algorithm used to determine the retransmission timeout. In
particular, when the timeout algorithm is rsre(3), an object of this type has the
semantics of the LBOUND quantity described in RFC 793.
This field displays the maximum timeout (in milliseconds) permitted by a TCP
implementation for the retransmission timeout. More refined semantics for objects of
this type depend upon the algorithm used to determine the retransmission timeout. In
particular, when the timeout algorithm is rsre(3), an object of this type has the
semantics of the UBOUND quantity described in RFC 793.
This field displays the maximum number of TCP connections the Switch can support. If
the maximum number is dynamic, this field displays -1.
This field displays the number of times TCP connections have made a direct transition
to the SYN-SENT state from the CLOSED state.
This field displays the number of times TCP connections have made a direct transition
to the SYN-RCVD state from the LISTEN state.
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.
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.
This field displays the number of TCP connections for which the current state is either
ESTABLISHED or CLOSE-WAIT.
This field displays the total number of segments received in a 32-bit count, including
those received in error. This count includes segments received on currently established
connections.
This field displays the total number of segments sent in a 32-bit count, including those
on current connections but excluding those containing only retransmitted octets.
This field displays the total number of TCP segments transmitted containing one or more
previously transmitted octets.
This field displays the total number of segments received with error (for example, bad
TCP checksums).
This field displays the number of TCP segments sent containing the RST flag.
This field displays the total number of segments received in a 64-bit count, including
those received in error. This count includes segments received on currently established
connections.
This field displays the total number of segments sent in a 64-bit count, including those
on current connections but excluding those containing only retransmitted octets.
This section displays the current TCP listeners.
This field displays the session ID.
This field displays the items on the receive queue in this connection.
This field displays the sequence number of the first unacknowledged segment on the
send queue in this connection.
This field displays the receiving window size in this connection. It determines the
amount of received data that can be buffered.
