MIB-II Object Types

tcpRtoMax
Syntax Integer
Access Read-only
Status Mandatory
Description The maximum value permitted by a TCP implementation for the retransmission time-out, measured
in milliseconds.
Note: More refined semantics for objects of this type depend upon the algorithm used to
determine the retransmission time-out. In particular, when the time-out algorithm is rsre
(3), an object of this type has the semantics of the UBOUND quantity described in RFC
793.
tcpMaxConn
Syntax Integer
Access Read-only
Status Mandatory
Description The limit on the total number of TCP connections the entity can support. In entities where the
maximum number of connections is dynamic, this object should contain the value -1.
tcpActiveOpens
Syntax Counter
Access Read-only
Status Mandatory
Description The number of times TCP connections have made a direct transition to the SYN-SENT state from
the CLOSED state.
tcpPassiveOpens
Syntax Counter
Access Read-only
Status Mandatory
Description The number of times TCP connections have made a direct transition to the SYN-RCVD state from
the LISTEN state.
