Parameter Description
Port Priority You can make a port more or less likely to become the Root Port. The

highest priority. If you change the value, you must reboot the switch.
Path Cost
Specifies the path cost of the port that is used to determine which
ports are the forwarding ports. The lowest number is the forwarding
port. The range is 1 - 65535. The default value base on IEEE802.1D:
10Mb/s = 50-600 100Mb/s = 10-60
If you change the value, you must reboot the switch.

The Port Mirror is a method of monitoring traffic in switched networks.
Traffic through ports can be monitored by one specific port. That is, traffic
going in or out of monitored ports will be duplicated into the mirror port.
