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 reconfiguration events, does not cause the spanning
tree to initiate reconfiguration when the interface changes state, and also
overcomes other STA-related time out problems. However, remember that
Edge Port should only be enabled for ports connected to an end-node
device.

This command configures the link type for Rapid Spanning Tree and
Multiple Spanning Tree. Use the
no
form to restore the default.

◆
Specify a point-to-point link if the interface can only be connected to
exactly one other bridge, or a shared link if it can be connected to two
or more bridges.
◆
When automatic detection is selected, the switch derives the link type
from the duplex mode. A full-duplex interface is considered a point-to-
point link, while a half-duplex interface is assumed to be on a shared
link.
◆
RSTP only works on point-to-point links between two bridges. If you
designate a port as a shared link, RSTP is forbidden. Since MSTP is an
extension of RSTP, this same restriction applies.
