conditions.
Automatic Configuration of SLB Policy Rules
When you configure an SLB cluster, a Quality of Service (QoS) policy condition, action, and rule are
automatically configured for it. In addition, the switch software automatically names the condition, action,
and rule by adding the prefix SLB-cond-, SLB-act-, and SLB-rule-, respectively, to the name of the SLB
cluster for each name.
For example, if you configured an SLB cluster called "Web_Server" a policy condition called "SLB-cond-
Web_Server," a policy action called "SLB-act-Web_Server," and a policy rule called "SLB-rule-
Web_Server" would be created.
Note that the user-configured policy condition associated with an SLB cluster is the condition used for the
automatically configured SLB policy rule. For example, if you configured an SLB cluster called
"Web_Server2" and associated it with the "cond1" condition, a policy rule called "SLB-rul-Web-Server2"
would be created with the "cond1" condition and the "SLB-act-Web_Server2" action.
You can display QoS policy rules with the
policy rule followed by the name of the rule. For example, the following commands display the policy
rule called "SLB-rul-Web_Server" and the policy rule called "SLB-rul-Web_Server2":
