Viewing statistics

Table 53 ICMP Statistics

Statistic Description

icmpOutAddrMaskReps The number of ICMP Address Mask Reply messages sent.

TCP statistics are described in the following table:

Table 54 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.
