GSLB zone configuration
39
• www.brocade.com (HTTP application)
• ftp.brocade.com (FTP application)
Some e-commerce sites also accept just a zone name as an alias for a specific application
within that zone. For example, a site might accept both “www.brocade.com” and
“brocade.com” as valid names for the HTTP application on the web host. In this case, the
second name has a null host name. No application is explicitly associated with the
“brocade.com” zone, but the DNS server is configured to associate “foundyrnet.com” with the
same IP addresses and application as “www.brocade.com” (for example, using address
records or alias records).
2. Select the policy you want to deploy to the GSLB ServerIron ADX product from the Host Policy
list. You can either select one of the policies defined under the Host Policy list or the policy that
is the default for the controller.
3. Select the name of the well-known port or application from the Host Port list for which you want
to provide GSLB.
4. Select the HTTP Settings check box to enable HTTP settings. For HTTP hosts, you can enable
HTTP health checks.
• If you enable HTTP settings, the URL field becomes available. Enter the URL that you want
to use for HTTP health checks.
• If you enable HTTP settings, the Status Codes list becomes available. When HTTP health
checks are performed, the DNS server responds with a status code. If the status code is
within a specified range, the server passes the health check. You can enter up to four
ranges.
5. Enter the minimum status code number in the Minimum column and the maximum status
code number in the Maximum column in the Status Codes list.
6. Click Add to add the status code ranges in the Status Codes list.
NOTE
To delete a range, select the range, then click Delete to remove it from the Status Codes list.
7. Click Add to add an IP address and weight in the IP Weights list.
The IP Weights list is used if IP Weights is specified in the selected policy (during site
configuration using the Site Configuration dialog box). You assign a weight to an IP address so
that the ServerIron ADX product distributes GSLB traffic among IP addresses in a DNS reply.
8. Enter the IP address to which you want to assign a weight in the IP Address column.
9. Enter a value from 0 through 100 in the Weight column. The default is 0.
NOTE
To delete an IP address and weight, select the entry, then click Delete to remove it from the IP
Weights list.
10. Continue adding hosts to the Add Hosts dialog box. When you have finished, click OK to add
the zone to the Hosts list of the Zone Configuration dialog box.
