Usage Information
Some non-Dell Networking systems which have hybrid ports participating in PVST+ transmit two kinds of BPDUs:
an 802.1D BPDU and an untagged PVST+ BPDU.
Dell Networking systems do not expect PVST+ BPDU on an untagged port. If this happens, Dell Networking OS
places the port in the Error-Disable state. This behavior might result in the network not converging. To prevent Dell
Networking OS from executing this action, use the no spanning-tree pvst err-disable command
cause invalid-pvst-bpdu.
