Task 1: Configure the Basics at the California Site
1. If the Browser-Based Interface (BBI) is to be used for managing the California switch,
change its service port.
GSLB uses service port 80 on the IP interface for DSSP updates. By default, the Web OS
Browser-Based Interface (BBI) also uses port 80. Both services cannot use the same port. If the
BBI is enabled (see the
/cfg/sys/http command in Chapter 7 of the Web OS Command
Reference), configure it to use a different port.
For example, enter the following command to change the BBI port to 8080:
2. On the California switch, define an IP interface.
The switch IP interface responds when asked to resolve client DNS requests. The IP interface
must have an IP route to the local real servers. The switch uses this path to determine if the real
servers can be reached via TCP/IP.
To configure an IP interface for this example, enter these commands from the CLI:
N OTE – This example assumes that all ports and IP interfaces use default VLAN 1, requiring
no special VLAN configuration for the ports or IP interface.
3. On the California switch, define the default gateway.
The router at the edge of the site acts as the default gateway to the Internet. To configure the
default gateway for this example, enter these commands from the CLI:
4. Configure the local DNS server to recognize the local GSLB switch as the authoritative
name server for the hosted services.
Determine the domain name that will be distributed to both sites and the host name for each
distributed service. In this example, the California DNS server is configured to recognize
200.200.200.100 (the IP interface of the California GSLB switch) as the authoritative name
server for “www.foocorp.com.”
>> # /cfg/sys (Select the System menu)
>> System# wport 8080 (Set service port 8080 for BBI)
>> System# /cfg/ip/if 1 (Select IP interface 1)
>> IP Interface 1# addr 200.200.200.100 (Assign IP address for the interface)
>> IP Interface 1# ena (Enable IP interface 1)
>> IP Interface 1# ../gw 1 (Select default gateway 1)
>> Default gateway 1# addr 200.200.200.101 (Assign IP address for the gateway)
>> Default gateway 1# ena (Enable default gateway 1)
