On the California switch, define a virtual server.
All client requests will be addressed to a virtual server IP address defined on the switch. Cli-
ents acquire the virtual server IP address through normal DNS resolution. HTTP uses well-
known TCP port 80. In this example, HTTP is configured as the only service running on this
virtual server IP address and, is associated with the real server group. For example:
>> Real server group 1# ../virt 1
>> Virtual server 1# vip 200.200.200.1
>> Virtual Server 1# service 80
>> Virtual server 1 http Service# group 1 (Associate virtual port to real group)
>> Virtual server 1 http Service# ../ena
