Table 17: Examples: Configuring Decision Policies and Links
Action	Command
Create a decision policy named policy_1	Avaya_ANS (config-engine)# decision-policy policy_1
Set a narrow winner-set width for all subnets associated with policy_1 The winner-set-width value is set to 3, and the extended width is set to 5 (used when load-optimization is enabled and the winner set defined by the winner-set-width value is empty).	Avaya_ANS (config-engine-policy)# winner-set-width 3 5
Prioritize any subnet associated with policy_1. Decisions involving these subnets are processed by CNA decision-maker before non-priority subnets.	Avaya_ANS (config-engine-policy)# priority-prefix
Accesses Link Configuration mode for link_1.	Avaya_ANS (config-engine-policy)# link link_1
For any subnet associated with policy_1, this command specifies that link_1 be chosen when it is in the winner set.	Avaya_ANS (config-engine-policy-link)# winner-set-priority prefer
Accesses Link Configuration mode for link_2.	Avaya_ANS (config-engine-policy)# link link_2
For any subnet associated with policy_1, this command specifies that link_2 be avoided. If link_2 is in the winner set, it will be the CNA system’s last choice.	Avaya_ANS (config-engine-policy-link)# winner-set-priority avoid
Exits Link Configuration mode.	Avaya_ANS (config-engine-policy-link)# end
Exits Policy Configuration mode.	Avaya_ANS (config-engine-policy-link)# end

After adding the above commands, a show running-config command shows the following block of commands in the CNA configuration:

decision-policy policy_1
 
  winner-set-width 3 5
 
  priority-prefix
 
  link link_1
 
    winner-set-priority prefer
 
    end
 
  link link_2
 
    winner-set-priority avoid
 
    end
 
  end
