Table 71 ICMP statistics
Statistics Description
icmpOutErrors The number of ICMP messages that this GbE2c did not send due to problems
discovered within ICMP such as a lack of buffer. This value should not include
errors discovered outside the ICMP layer such as the inability of IP to route the
resultant datagram. In some implementations there may be no types of errors that
contribute to this counter's value.
icmpOutDestUnreachs The number of ICMP Destination Unreachable messages sent.
icmpOutTimeExcds The number of ICMP Time Exceeded messages sent.
icmpOutParmProbs The number of ICMP Parameter Problem messages sent.
icmpOutSrcQuenchs The number of ICMP Source Quench (buffer almost full, stop sending data)
messages sent.
icmpOutRedirects The number of ICMP Redirect messages sent.
icmpOutEchos The number of ICMP Echo (request) messages sent.
icmpOutEchoReps The number of ICMP Echo Reply messages sent.
icmpOutTimestamps The number of ICMP Timestamp (request) messages sent.
icmpOutTimestampReps The number of ICMP Timestamp Reply messages sent.
icmpOutAddrMasks The number of ICMP Address Mask Request messages sent.
icmpOutAddrMaskReps The number of ICMP Address Mask Reply messages sent.
The following table describes the Transmission Control Protocol (TCP) statistics:
Table 72 TCP statistics
Statistics Description
tcpRtoAlgorithm The algorithm used to determine the timeout value used for retransmitting
unacknowledged octets.
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 Request For Comments (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.
tcpMaxConn The limit on the total number of TCP connections the GbE2c 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.
