Table 12 lists the RSTP port costs with
Auto-Detect when the port is part of a
port trunk.
portpriority
Specifies the port’s priority. This parameter is used as a
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, for a total of 16 increments, as
shown in Table 13. You specify the increment that
corresponds to the desired value. The default is 128,
which is 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. The
options are:
