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 19. 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:
yes, on, true The port is an edge port. The options
are equivalent. This is the default.
no, off, false The port is not an edge port. The
options are equivalent.
ptp or Defines whether the port is functioning as a point-
pointtopoint to-point port. The parameters are equivalent. This type
of port is connected to a device operating at full-duplex
mode. The options are:
100 Mbps 20,000
1000 Mbps 2,000
