cost The path cost for the port. (Range: 1-200,000,000)) The recommended range
is:
• 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
Command Mode
Interface Configuration (Ethernet, Port Channel)
Usage Guidelines
This command is used by the Spanning Tree Algorithm 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.
When the spanning-tree pathcost method command is used and is set to short, the maximum value for
path cost is 65,535.
Example
The following is sample output from the spanning-tree cost command.
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree cost 50
Console(config-if)#
16.213 spanning-tree edge-port
This command specifies an interface as an edge port. Use the no form to restore the default.
Syntax Description
