This command defines the priority for the use of a port in the Spanning
Tree Algorithm. If the path cost for all ports on a switch are the same, the
port with the highest priority (i.e., lowest value) will be configured as an
active link in the Spanning Tree. This makes a port with higher priority less
likely to be blocked if the Spanning Tree Protocol is detecting network
loops. Where more than one port is assigned the highest priority, the port
with lowest numeric identifier will be enabled.

You can enable this option if an interface is attached to a LAN segment that
is at the end of a bridged LAN or to an end node. Since end nodes cannot
cause forwarding loops, they can pass directly through to the spanning tree
forwarding state. Specifying edge ports provides quicker convergence for
devices such as workstations or servers, retains the current forwarding
database to reduce the amount of frame flooding required to rebuild
address tables during re-configuration events, does not cause the spanning
tree to initiate re-configuration when the interface changes state, and also
