when the Path Cost Method is set to short (page 3-63), 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
Web – Click Spanning Tree, MSTP, Port Configuration or Trunk
Configuration. Enter the priority and path cost for an interface, and click
Apply.
