Usage
Information
By default, Dell Networking OS implements an optimized flush mechanism for
PVST+. This 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.
