TCP Statistics
The following table describes the TCP statistics fields.
icmpOutRedirects The number of ICMP Redirect messages sent. For a host, this object will
always be zero, since hosts do not send redirects.
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.
Table 13-5 TCP Statistics
Field 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
time-
out
. 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
time-
out
. 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 entity (the switch) can sup-
port. 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.
