The following QoS policy conditions are supported individually and in combination with each other when 
used to configure SLB condition clusters:

 for more information about configuring and displaying QoS policy 

conditions.

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 

 command. To use this command, enter show 

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”:

-> show policy rule SLB-rule-Web_Server

You can also use the
