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, the system places the port in the Error-Disable state. This behavior might
result in the network not converging. To prevent the system from executing this
action, use the no spanning-tree pvst err-disable command cause
invalid-pvst-bpdu.
