TCP/IPX Connection Mib Specification
Status of this Memo
This document defines an Experimental Protocol for the Internet
community. This does not specify an Internet standard of any kind.
Discussion and suggestions for improvement are requested.
Distribution of this memo is unlimited.
IESG Note:
Internet Engineering Steering Group comment from the Area Director
for Transport Services: Please note well that this memo is an
individual product of the author. Implementation experience,
particularly on the effectiveness of the protocols in dual-stack
environments, is needed.
1. Introduction
Traditionally, TCP and UDP runs over IP. STD 17, RFC 1213 defines
TCP connection MIB object and UDP listener object assuming just that.
For TCP and UDP running over IPX, tcpConnTable and udpTable objects
from RFC 1213 cannot be used since they define the address to be of
type IpAddress. As such, we need to define new objects that can
properly describe TCP and UDP connections over IPX.
New MIB objects, tcpIpxConnTable, udpIpxTable, tcpUnspecConnTable and
udpUnspecTable are presented in this paper, to be used in place of
tcpConnTable and udpListenerTable when TCP and UDP are running over
IPX.

DESCRIPTION
"The state of this TCP connection.
The only value which may be set by a management
station is deleteTCB(12). Accordingly, it is
appropriate for an agent to return a `badValue'
response if a management station attempts to set
this object to any other value.
If a management station sets this object to the
value deleteTCB(12), then this has the effect of
deleting the TCB (as defined in RFC 793) of the
corresponding connection on the managed node,
resulting in immediate termination of the
connection.
As an implementation-specific option, a RST
segment may be sent from the managed node to the
other TCP endpoint (note however that RST

segments are not sent reliably)."

the listen state which is willing to accept
