4.8.1.4 Port Parameters
This 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.
Path Cost: The valid value is from 1 to 200000000. The higher cost is
more likely to be blocked by STP if a network loop is detected.
Priority: Set 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 240.
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.
Edge Port: An edge port is the same as a Port Fast-enabled port, and
you should enable it only on ports that connect to a single end station.
Click OK to make the settings effective. Click Reload to refresh the
settings to current value.
