Command Usage
• 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 ECN330-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 a port
is designated as a shared link, RSTP is forbidden. Since MSTP is an
extension of RSTP, this same restriction applies.
