It is dedicated to reflect IEEE Std 802.1s" REVISION "200511110000Z" -- 11 Nov 2005 DESCRIPTION "The draft has been changed as a result of discussion in mailing list STDS-802-1-L@listserv.ieee.org. Name of the uploaded file is ruzin-mstp-mib-04.txt. Main changes: 1. Following objects have been deleted (use BIDGE-MIB and RSTP-MIB): mstpGenBridgeMaxAge, mstpGenBridgeHelloTime, mstpGenBridgeForwardDelay, mstpGenMaxAge, mstpGenHelloTime, mstpGenForwardDelay, mstpGenHoldTime, mstpGenMigrateTime, mstpGenPathCostDefault, mstpPortUpTime mstpPortAdminExternalPathCost, mstpPortOperExternalPathCost mstpPortAdminEdge, mstpPortOperEdge, mstpPortAdminPointToPoint mstpPortOperPointToPoint, mstpPortHelloTime and mstpPortProtocolMigration 2. Clause '4 Relation to Original Bridge MIB' has been rewritten 3. Explanations have been added/changed for some of objects 4. The object mstpGenForceVersion has been renamed to mstpGenProtocolVersion 5. The object mstpGenCapable has been renamed to mstpVesrionsSupported and its types has been changed to BITS. 6. The object mstpXstDesignatedBridge has been removed; a new object mstpPortDesignatedBridge has been inserted into mstpPortTable instead. 7. Instead mstpMapTable two another tables are proposed: mstMapTable and mstVlanTable."

The latter defines a greater than zero value used to identify a Port in the managed Bridge. This extension permits the additional value of zero. the value zero is object-specific and must therefore be defined as part of the description of any object which uses this syntax. Examples of the usage of zero might include situations where Port was unknown, or when none or all Ports need to be referenced."
