Configuring Server Load Balancing
This section describes the steps for configuring an SLB Web hosting solution. In the following
procedure, many of the SLB options are left to their default values. See
“Additional Server
Load Balancing Options” on page 128 for more options.
The following is required prior to configuration:
n
You must be connected to the switch Command Line Interface (CLI) as the administrator.
n
The SLB software must be enabled.
N OTE – For details about any of the menu commands described in this example, see your
Web OS Command Reference.
1. Assign an IP address to each of the real servers in the server pool.
The real servers in any given real server group must have an IP route to the switch that per-
forms the SLB functions. This IP routing is most easily accomplished by placing the switches
and servers on the same IP subnet, although advanced routing techniques can be used as long
as they do not violate the topology rules outlined in
“Network Topology Requirements” on
page 122 .
For this example, the three Web-host real servers have been given the following IP addresses
on the same IP subnet:
N OTE – An imask option can be used to define a range of IP addresses for real and virtual
servers (see “IP Address Ranges Using imask” on page 129 ).
