The CIST Port Table. Each row in the Table represents information regarding a specific Port within the Bridge's Bridge Protocol Entity, for the CIST. The values of all writable objects in this table MUST be retained across reinitializations of the management system. Note that entries will exist in this table only for Bridge components for which the corresponding instance of ieee8021SpanningTreeVersion (from the IEEE8021-SPANNING-TREE-MIB) has a value of mstp(3). This table contains objects corresponding to the following items from 12.8.2.1, 12.8.2.3, and 12.8.2.5. Some of those items are provided in the IEEE8021-SPANNING-TREE-MIB as noted below. From 12.8.2.1: Items a), d), e), and i) through w) are defined in this table The remaining items are covered in the IEEE8021-SPANNING-TREE-MIB: b) ieee8021SpanningTreePortState c) ieee8021SpanningTreePortPriority d) ieee8021SpanningTreePortPathCost f) ieee8021SpanningTreePortDesignatedCost g) ieee8021SpanningTreePortDesignatedBridge h) ieee8021SpanningTreePortDesignatedPort From 12.8.2.3: Items a), b), and d) through h) are defined in this table (item a is the index) The remaining items are covered in the IEEE8021-SPANNING-TREE-MIB: b) ieee8021SpanningTreePortPathCost, c) ieee8021SpanningTreePortPriority From 12.8.2.5: All items are defined in this table Also from 12.8.2.1: Items u), v), w), and x) are defined in this table Also from 12.8.2.3: Items i), j), k), and l) are defined in this table
