Table 70 ICMP statistics
Statistics
Description
icmpOutErrors
The number of ICMP messages that this switch 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 71 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 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.
