GSLB Manager

The Global Server Load Balancing (GSLB) Manager allows you to configure GSLB policies for a ServerIron ADX product. The ServerIron ADX product on which the GSLB protocol is enabled serves as a proxy to the Domain Name System (DNS) servers and evaluates the IP addresses in the DNS replies from the DNS server for which the ServerIron ADX product is a proxy. Based on the results of the evaluation, the GSLB ServerIron ADX product can change the order of the addresses in the reply so that the “best” host address for the client is on top.

The GSLB Manager feature is supported for ADP products (ServerIron version 09.0 and later and ADX version 12.0 or later) only. For more information on GSLB, refer to the ServerIron manuals.

Configuration requirements

Before using the GSLB Manager, confirm the following requirements:

The GSLB Manager privilege is in your Management application user account or role.

The ServerIron ADX products to which the policies, sites, and zones will be deployed are listed in the Network Object Manager tree. If they are not, make sure they are on the network that is being managed by the Management application. Then run discovery or add the ServerIron ADX products to the Management application using Network Object Manager.
