Definition
Single IEEE 802.1D-compliant spanning tree for the entire bridge.
In 802.1D spanning tree mode, there is one root Bridge for the whole
network, regardless of whether the switches support VLANs or not.
Only one active data path is supported for all VLANs from any point in
the network to any other point
Note: When the spanning tree mode is set to IEEE 802.1D, Bridge
Protocol Data Units (BPDUs) are sent out ports in Clear (non-tagged)
format even if the port has a tagged format (3Com, IEEE 802.1Q or
Cisco ISL) defined.
