To configure the switch for DNS load balancing, perform the following procedure:
1. Before you can configure DNS load balancing, ensure that the switch has already been
configured for basic SLB with the following tasks:
n Assign an IP address to each of the real servers in the server pool.
n Define an IP interface on the switch.
n Define each real server (DNS server address).
n Assign servers to real server groups.
n Define virtual servers and services.
n Enable SLB.
For information on how to configure your network for SLB, see Chapter 6, “Server Load
Balancing.”
n Define server port and client port.
2. Enable DNS load balancing.
3. Enable delayed binding.
4. Define the host names.
5. Apply and save your configuration changes.
6. Identify the defined string IDs.
For easy configuration and identification, each defined string has an ID attached, as shown in
the following example:
>> # /cfg/slb/virt 1 (Select the virtual server)
>> Virtual Server 1 # service 53
(Select the DNS service)
>> Virtual Server 1 DNS Service # dnsslb ena
(Enable DNS SLB)
>> Virtual Server 1 DNS Service# dbind ena
>> # /cfg/slb/layer7/slb/add www.[abcdefg]*.com
>> Server Loadbalance Resource# add www.[hijklm]*.com
>> Server Loadbalance Resource# add www.[nopqrst]*.com
>> Server Loadbalance Resource# add www.[uvwxyz]*.com
>> # /cfg/slb/layer7/slb/cur
