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
connected to any device running STP or RSTP.
Selections are:
