Download standard MIB format if you are planning to load a MIB file into some system (OS, Zabbix, PRTG ...) or view it with a MIB browser. CSV is more suitable for analyzing and viewing OID' and other MIB objects in excel. JSON and YAML formats are usually used in programing even though some systems can use MIB in YAML format (like Logstash).
Keep in mind that standard MIB files can be successfully loaded by systems and programs only if all the required MIB's from the "Imports" section are already loaded.
The tree-like SNMP object navigator requires no explanations because it is very simple to use. And if you stumbled on this MIB from Google note that you can always go back to the home page if you need to perform another MIB or OID lookup.

A ieee8021SpanningTreeTopologyChange notification is sent by a Bridge when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The notification is not sent if a ieee8021SpanningTreeNewRoot notification is sent for the same transition.

This time value, measured in units of hundredths of a second, controls how fast a port changes its spanning state when moving towards the Forwarding state. The value determines how long the port stays in each of the Listening and Learning states, which precede the Forwarding state. This value is also used when a topology change has been detected and is underway, to age all dynamic entries in the Filtering Database. [Note that this value is the one that this Bridge is currently using, in contrast to ieee8021SpanningTreeBridgeForwardDelay, which is the value that this Bridge and all others would start using if/when this Bridge were to become the root.]

Note that 802.1D-1998 specifies that the range for this parameter is related to the value of ieee8021SpanningTreeBridgeMaxAge. The granularity of this timer is specified by 802.1D-1998 to be 1 second. An agent may return an SNMP badValue error (or its equivalent if another protocol is used) if a set is attempted to a value that is not a whole number of seconds. The value of this object MUST be retained across reinitializations of the management system.

If this object is used to set the Path Cost it is possible to restore the default setting using the ieee8021SpanningTreeRstpPortAdminPathCost object. Table 13-4 recommends defaults and ranges for Port Path Cost values, in inverse proportion to the speed of the attached LAN. If this object is used to set the Path Cost it is possible to restore the default setting using the ieee8021MstpPortAdminPathCost object. The value of this object MUST be retained across reinitializations of the management system.

Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).
                 ieee8021SpanningTreeRstpPortProtocolMigration 1.3.111.2.802.1.1.3.1.2.1.12 truthvalue read-write
When operating in RSTP (version 2) mode, writing true(1) to this object forces this port to transmit RSTP BPDUs. Any other operation on this object has no effect and it always returns false(2) when read.

The administrative value of the Edge Port parameter. A value of true(1) indicates that this port should be assumed as an edge-port, and a value of false(2) indicates that this port should be assumed as a non-edge-port. Setting this object will also cause the corresponding instance of ieee8021SpanningTreeRstpPortOperEdgePort to change to the same value. Note that even when this object's value is true(1), the value of the corresponding instance of ieee8021SpanningTreeRstpPortOperEdgePort can be false(2) if a BPDU has been received. The value of this object MUST be retained across reinitializations of the management system.
                 ieee8021SpanningTreeRstpPortOperEdgePort 1.3.111.2.802.1.1.3.1.2.1.14 truthvalue read-only
The operational value of the Edge Port parameter. The object is initialized to the value of the corresponding instance of ieee8021SpanningTreeRstpPortAdminEdgePort. When the corresponding instance of ieee8021SpanningTreeRstpPortAdminEdgePort is set, this object will be changed as well. This object will also be changed to false(2) on reception of a BPDU.
                 ieee8021SpanningTreeRstpPortAdminPathCost 1.3.111.2.802.1.1.3.1.2.1.15 integer32 read-write
The administratively assigned value for the contribution of this port to the path cost of paths toward the spanning tree root. Writing a value of '0' assigns the automatically calculated default Path Cost value to the port. If the default Path Cost is being used, this object returns '0' when read. This complements the object ieee8021SpanningTreePortPathCost, which returns the operational value of the path cost. The value of this object MUST be retained across reinitializations of the management system.
         ieee8021SpanningTreePortExtensionTable 1.3.111.2.802.1.1.3.1.3 no-access

The administrative value of the Auto Edge Port parameter. A value of true(1) indicates if the Bridge detection state machine (BDM, 13.31) is to detect other Bridges attached to the LAN, and set ieee8021SpanningTreeRstpPortOperEdgePort automatically. The default value is true(1) This is optional and provided only by implementations that support the automatic identification of edge ports. The value of this object MUST be retained across reinitializations of the management system.
                 ieee8021SpanningTreeRstpPortAutoIsolatePort 1.3.111.2.802.1.1.3.1.3.1.2 truthvalue read-only
The operational value of the Isolate Port parameter. A value of true(1) indicates a Designated Port will transition to discarding if both ieee8021SpanningTreeRstpPortAdminEdgePort and ieee8021SpanningTreeRstpPortAutoEdgePort are FALSE and the other Bridge presumed to be attached to the same point-to-point LAN does not transmit periodic BPDUs. This is optional and provided only by implementations that support the automatic identification of edge ports.
                 ieee8021SpanningTreeRstpPortIsolatePort 1.3.111.2.802.1.1.3.1.3.1.3 truthvalue read-only
The operational value of the Isolate Port parameter. A value of true(1), Set by the Bridge detection state machine (BDM, 13.31), indicates when the Spanning Tree Protocol Entity of a neighboring Bridge has apparently failed .
