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.

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.
