MIB-II Object Types
1
The TCP Group
Implementation of the TCP group is mandatory for all systems that implement the TCP.
Note: Instances of object types that represent information about a particular TCP connection are
transient; they persist only as long as the connection in question.
tcpRtoAlgorithm
Syntax
Access Read-only
Status Mandatory
Description The algorithm used to determine the time-out value used for retransmitting unacknowledged octets.
tcpRtoMin
Syntax Integer
Access Read-only
Status Mandatory
Description The minimum 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 LBOUND quantity described in RFC
793.
Value Declaration Description
Integer 1 (other)
2 (constant)
