CONFIGURATION
Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module
By default FTOS implements an optimized flush mechanism for PVST+. This 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, this knob command can be turned
on to enable flushing MAC addresses upon receiving every topology change notification.
Set the PVST+ bridge-priority for a VLAN or a set of VLANs.
vlan <vlan-id> bridge-priority value
