• Admin MST Path Cost – This parameter is used by the MSTP to
determine the best path between devices. Therefore, lower values
should be assigned to ports attached to faster media, and higher values
assigned to ports with slower media. (Path cost takes precedence over
port priority.) Note that when the Path Cost Method is set to short
(page 241), the maximum path cost is 65,535.
By default, the system automatically detects the speed and duplex
mode used on each port, and configures the path cost according to the
values shown below. Path cost “0” is used to indicate auto-configuration
mode.
• Range –
Ethernet: 200,000-20,000,000
Fast Ethernet: 20,000-2,000,000
Gigabit Ethernet: 2,000-200,000
• Default –
Ethernet – Half duplex: 2,000,000; full duplex: 1,000,000; trunk:
500,000
Fast Ethernet – Half duplex: 200,000; full duplex: 100,000; trunk:
50,000
Gigabit Ethernet – Full duplex: 10,000; trunk: 5,000
