4.5.1.4 Port Parameters
This page contains a display window to show the current configuration for each
port. You can select a port then edit it. Click Modify to change the port setting
for spanning-tree. The following fields are available:
Instance ID(MSTP Only): a spanning-tree instance, you can configure
MSTP on your switch to map multiple VLANs into a single STP instance.
Priority: sets the port priority in the switch. Low numeric value indicates a
high priority. The port with lower priority is more likely to be blocked by STP
if a network loop is detected. The valid value is from 0 to 255.
Path Cost: the valid value is from 1 to 65535. The higher cost is more likely
to be blocked by STP if a network loop is detected.
Link Type: By default, the link type is determined from the duplex mode
of the interface: a full-duplex port is considered to have a point-to-point
connection; a half-duplex port is considered to have a shared connection.
