Variable definitions

The following table describes the fields of TCP tab.

Field Description
ActiveOpens Indicates the number of times TCP connections have made a direct transition to the SYN-SENT state from the CLOSED state.
PassiveOpens Indicates the number of times TCP connections have made a direct transition to the SYN-RCVD state from the LISTEN state.
AttemptFails Indicates 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.
EstabResets Indicates 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.
CurrEstab Indicates the number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT.
InSegs Indicates the total number of segments received, including those received in error. This count includes segments received on currently established connections.
OutSegs Indicates the total number of segments sent, including those on current connections but excluding those containing only retransmitted octets.
RetransSegs Indicates the total number of segments retransmitted -- that is, the number of TCP segments transmitted containing one or more previously transmitted octets.
InErrs Indicates the total number of segments received in error (for example, bad TCP checksums).
OutRsts Indicates the number of TCP segments sent containing the RST flag.
HCInSegs Indicates the number of segments received, including those received in error. This count includes segments received on currently established connections. This object is the 64-bit equivalent of InSegs.
HCOutSegs Indicates the number of segments sent, including those on current connections, but excluding those containing only retransmitted octets. This object is the 64-bit equivalent of OutSegs.
