Define a virtual server.
All client requests will be addressed to a virtual server IP address on a virtual server defined on
the switch. Clients acquire the virtual server IP address through normal DNS resolution. In this

(Assign a virtual server IP address)
>> Virtual server 1# ena
(Enable the virtual server)
