Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.9(0.0) Introduced on the C9010.
9.2(1.0) Introduced on the Z9500.
8.3.19.0 Introduced on the S4820T.
8.3.11.1 Introduced on the Z9000.
8.3.7.0 Introduced on the S4810.
8.2.1.0 Introduced.
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.
