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
.
