History
Usage
Some non-Dell Networking systems which have hybrid ports participating in PVST+
Information
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.

Command
Version 8.3.16.1
History
Usage By default, the system implements an optimized flush mechanism for PVST+. This
Information implementation helps in flushing the MAC addresses only when necessary (and less
often) allowing for faster convergence during topology changes. However, if a
standards-based flush mechanism is needed, you can turn this knob command on
to enable flushing MAC addresses after receiving every topology change
notification.
vlan bridge-priority
Set the PVST+ bridge-priority for a VLAN or a set of VLANs.
Syntax
vlan vlan-id bridge-priority value
To return to the default value, use the no vlan bridge-priority command.
