Usage guidelines
The link cost of a TRILL port can be automatically calculated by the system or manually configured:
• When a link cost is manually configured, the manually configured link cost takes effect whether or
not automatic link cost calculation is enabled.
• When a link cost is not manually configured and automatic link cost calculation is enabled, the
automatically calculated link cost takes effect.
• When a link cost is not manually configured and automatic link cost calculation is not enabled, 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.
