STATUS—Not supported
• TcpAttemptFails: The number of times TCP connections have made a direct transition from either the
SYN-SENT state or the SYN-RCVD state to the CLOSED state plus the number of times TCP
connections have made a direct transition from the SYN-RCVD state to the LISTEN state.
STATUS—Supported
• TcpEstabResets: The number of times TCP connections have made a direct transition from either the
ESTABLISHED state or the CLOSE-WAIT state to the CLOSED state.
STATUS—Not supported
• TcpCurrEstab: The number of TCP connections for which the current state is either ESTABLISHED or
CLOSE-WAIT.
STATUS—Supported
• TcpInSegs: The total number of segments received, including those received in error. This count
includes segments received on currently established connections.
STATUS—Supported
• TcpOutSegs: The total number of segments sent, including those on current connections but excluding
those containing only retransmitted octets.
STATUS—Supported
• TcpSlowOutSegs: A subset of TcpOutSegs that provides the total number of segments sent in the slow
path.
STATUS—Supported
• TcpRetransSegs: The total number of segments retransmitted (the number of TCP segments transmitted
that contain one or more previously transmitted octets).
STATUS—Supported
• TcpInErrs: The total number of TCP segments received in error (for example, a bad TCP header).
Checksum errors are not included in this counter.
STATUS—Supported
• TcpOutRsts: The number of TCP segments sent that contain the reset (RST) flag.
STATUS—Supported
• TcpOutRsts: The number of TCP segments sent that contain the reset (RST) flag.
STATUS—Supported
• TcpOutCollapsed: The total number of times that two outgoing packets were collapsed to form a
single packet during retransmission.
STATUS—Supported
• TcpTimeWaitConns: The total number of connections that are currently in the TIME_WAIT state.
STATUS—Supported
• IpInReceives: The total number of input datagrams received from interfaces, including those received
in error.
STATUS—Supported
• IpInHdrErrors: The number of input datagrams discarded due to errors in their IP headers (including
bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors
discovered in processing their IP options, and so forth).
