-> ip slb server ip 128.241.130.135 cluster WorldWideWeb admin status disable 

weight 8

Follow the steps below for a quick tutorial on how to configure a QoS policy condition cluster:

1 Create the QoS policy condition that will classify traffic for the SLB cluster. For example:

-> policy network group SOURCE 100.0.0.1 100.0.0.2 100.0.0.3 100.0.0.4 

-> policy condition c1 source network group SOURCE destination tcp port 80

-> qos apply

2 Configure the SLB cluster using the 

 command with the condition parameter.

For example:

-> ip slb cluster Intranet condition c1

3 Assign physical servers to the SLB condition cluster and specify a relative weight for each server 
(default value for weight is 1) with the 

 command. For example:

-> ip slb server ip 103.10.50.1 cluster Intranet
-> ip slb server ip 103.10.50.2 cluster Intranet weight 4
-> ip slb server ip 103.10.50.3 cluster Intranet admin status disable weight 2

Note. As an option, you can configure an SLB server as a backup server. See 

 for more information.

As an option, you can verify your SLB settings by entering 

 followed by the name of 

the SLB cluster. For example:

-> show ip slb cluster Intranet
