Table 62 TCP statistics
Statistics Description
tcpRtoMax The maximum value permitted by a TCP implementation for the retransmission timeout,
measured in milliseconds. 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.
tcpMaxConn The limit on the total number of TCP connections the switch can support. In entities
where the maximum number of connections is dynamic, this object should contain the
value -1.
tcpActiveOpens The number of times TCP connections have made a direct transition to the SYN-SENT
state from the CLOSED state.
tcpPassiveOpens The number of times TCP connections have made a direct transition to the SYN-RCVD
state from the LISTEN state.
tcpAttemptFails 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 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.
tcpInSegs The total number of segments received, including those received in error. This count
includes segments received on currently established connections.
tcpOutSegs The total number of segments sent, including those on current connections but excluding
those containing only retransmitted octets.
tcpRetransSegs The total number of segments retransmitted, that is, the number of TCP segments
transmitted containing one or more previously transmitted octets.
tcpInErrs The total number of segments received in error (for example, bad TCP checksums).
tcpCurBuff The total number of outstanding memory allocations from heap by TCP protocol stack.
tcpCurConn The total number of outstanding TCP sessions that are currently opened.
tcpOutRsts The number of TCP segments sent containing the reset (RST) flag.

The following table describes the User Datagram Protocol (UDP) statistics:
Table 63 UDP statistics
Statistics Description
udpInDatagrams The total number of UDP datagrams delivered to the switch.
udpOutDatagrams The total number of UDP datagrams sent from this switch.
udpInErrors The number of received UDP datagrams that could not be delivered for reasons other
than the lack of an application at the destination port.
udpNoPorts The total number of received UDP datagrams for which there was no application at the
destination port.
