tie breaker when two or more ports are determined to
have equal costs to the root bridge. The range is 0 to
240 in increments of 16. There are sixteen increments.
You specify the increment of the desired value. The
default is 128 (increment 8).
edgeport Defines whether the port is functioning as an edge
port. An edge port is connected to a device
operating at half-duplex mode and is not

Selections are:
yes The port is an edge port. This is the
default.
no The port is not an edge port.
pointtopoint Defines whether the port is functioning as a point-
to-point port. This type of port is connected to a
device operating at full-duplex mode. Selections
are:
yes The port is an point-to-point port.
no The port is not an point-to-point port.
autoupdate The port’s status is determined
automatically. This is the default.
