Quick Steps for Configuring Server Load Balancing (SLB)

Configuring Server Load Balancing

page 44-4

OmniSwitch AOS Release 6 Network Configuration Guide

Follow the steps below for a quick tutorial on configuring parameters for SLB. Additional information on 
how to configure each command is given in the subsections that follow. Note that this example configures 
a VIP cluster. See the tutorial on 

 for quick steps on configuring a QoS policy condition cluster.

1 Enable SLB globally with the 

 command as shown below:

-> ip slb admin enable

2 Configure the SLB VIP cluster using the 

 command with the vip parameter. For example:

-> ip slb cluster WorldWideWeb vip 128.241.130.204

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

 command. For example:

-> ip slb server ip 128.241.130.127 cluster WorldWideWeb 

-> ip slb server ip 128.241.130.109 cluster WorldWideWeb weight 4 

-> ip slb server ip 128.241.130.115 cluster WorldWideWeb weight 6 

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

weight 8

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 WorldWideWeb

Weight = 4, Availability (%) = 100

Server 128.241.130.115

Admin status = Enabled, Operational Status = In Service,

Weight = 6, Availability (%) = 98

Server 128.241.130.127

Admin status = Enabled, Operational Status = Discovery,

Weight = 1, Availability (%) = 0

Server 128.241.130.135

Admin status = Disabled, Operational Status = Disabled,

Weight = 8, Availability (%) = 0

An example of what these configuration commands look like entered sequentially on the command line:

-> ip slb admin enable

-> ip slb cluster WorldWideWeb vip 128.241.130.204

-> ip slb server ip 128.241.130.127 cluster WorldWideWeb

-> ip slb server ip 128.241.130.109 cluster WorldWideWeb weight 4
