Usage guidelines

The link cost of a TRILL port can be automatically calculated by the system or manually set.

• A manually set link cost takes precedence over a calculated link cost.

• If no link cost is set and automatic link cost calculation is enabled, the calculated link cost takes effect.

• If no link cost is set and automatic link cost calculation is disabled, the default link cost of 2000 is used.

The system automatically calculates the link cost of a TRILL port by using the following formula: link cost = 20000000000000/interface baud rate.

Examples
