    Most rákerestem és nem egészen csak az, amit írtam. Ezeket találtam:

    There can be different types of STP inconsistencies:

    Loop inconsistency—This is detected by the Loop Guard feature. For more information, refer to Spanning-Tree Protocol Enhancements using Loop Guard and BPDU Skew Detection Features.

    Root inconsistency—This is detected by the Root Guard feature. For more information, refer to Spanning-Tree Protocol Root Guard Enhancement.

    EtherChannel inconsistency—This is detected by the EtherChannel consistency detection feature. For more information, refer to Understanding EtherChannel Inconsistency Detection.

    Port VLAN ID (PVID) inconsistency—A per-VLAN spanning tree (PVST+) Bridge Protocol Data Unit (BPDU) is received on a different VLAN than it was originated: (Port VLAN ID Mismatch or *PVID_Inc).

    Type inconsistency—A PVST+ BPDU is received on a non-802.1Q trunk.
