ICMP Statistics
Statistic Description
icmpOutAddrMaskReps
The number of ICMP Address Mask Reply messages sent.
TCP statistics are described in the following table:
Table 55
TCP Statistics
Statistic Description
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.
tcpRtoAlgorithm
The algorithm used to determine the timeout value used for retransmitting unacknowledged
octets.
tcpMaxConn
The limit on the total number of TCP connections the entity (the switch) can support. In entities
where the maximum number of connections is dynamic, this object should contain the value -1.
tcpRtoMin
The minimum 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 LBOUND quantity described in RFC 793.
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.
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 SYNRCVD 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.
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 RST flag.
All TCP allocated control blocks
Destinate Address Switch IP address of TCP connections.
