winner-set-width

Sets a winner-set value, which establishes an acceptable range for preferred-route performance scores--to be in the winner-set (the set of service provider links from which the best performing route will be selected), a route’s performance score must be within this range.

winner-set-width <value> [ <val_2> ]
 
no winner-set-width
 

• value--maximum allowable difference in metrics among links considered to be in the winner set; range: 1 through 1000
• val_2--maximum allowable difference in metrics among links considered to be in the winner set if winner set contains no links because of load optimization; range: 1 through 1000

Must be in engine or policy configuration mode (config-engine or config-engine-policy), both of which require privileged-level access.

Use once for global value, and once per policy configuration.

value--20

val_2--will be set to value

All routes whose performance metrics are lower than the lowest performance score plus the winner-set-width value are considered to fall within the winner-set. (Penalties assigned using the penalty command are factored into the performance score calculation.)

For information about how the CNA decision maker process selects the best performance route from the winner set, see Route Assertion in Chapter 3: Adaptive Path Control of the CNA Adaptive Path Controller Guide.

Use the no form of the command to reset value to its default.
