Statistics

Description

 

 

tcpRtoAlgorithm

The algorithm used to determine the timeout value used for retransmit-

 

ting unacknowledged octets.

 

 

tcpRtoMin

The minimum value permitted by a TCP implementation for the retrans-

 

mission 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 retrans-

 

mission 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 entity (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 tran-

 

sition to the LISTEN state from the SYN-RCVD state.
