The Common and Internal Spanning Tree (CIST) Table. Each row in the table represents information regarding a Bridge's Bridge Protocol Entity for the CIST. 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 12.8.1.1 and 12.8.1.3. Some of those items are provided in the IEEE8021-SPANNING-TREE-MIB as noted below. From 12.8.1.1: Items a), c), o), p), and q) are defined in this table The remaining items are covered in the IEEE8021-SPANNING-TREE-MIB: b) ieee8021SpanningTreeTimeSinceTopologyChange c) ieee8021SpanningTreeTopChanges e) ieee8021SpanningTreeDesignatedRoot f) ieee8021SpanningTreeRootCost g) ieee8021SpanningTreeRootPort h) ieee8021SpanningTreeMaxAge i) ieee8021SpanningTreeForwardDelay j) ieee8021SpanningTreeBridgeMaxAge k) ieee8021SpanningTreeBridgeHelloTime l) ieee8021SpanningTreeBridgeForwardDelay m) ieee8021SpanningTreeHoldTime n) ieee8021SpanningTreeVersion From 12.8.1.3: Item g) is defined in this table The remaining items are covered in the IEEE8021-SPANNING-TREE-MIB: a) ieee8021SpanningTreeBridgeMaxAge b) ieee8021SpanningTreeBridgeHelloTime c) ieee8021SpanningTreeBridgeForwardDelay d) ieee8021SpanningTreePriority e) ieee8021SpanningTreeVersion f) ieee8021RstpStpExtTxHoldCount
