Brocade Communications Systems 12.4.00 manual Host a Flashback

Displaying GSLB information 1

In this example, ServerIron ADX slb-1 is the active ServerIron ADX for VIPs 209.157.22.100 and 109.157.22.101 and ServerIron ADX slb-2 is the default active ServerIron ADX for VIPs 209.157.22.103 and 209.157.22.104. Although this example has both VIPs for a host active on the same ServerIron ADX, you can just as easily configure the VIPs so that both ServerIron ADXs have active VIPs for the same host.

NOTE

This example does not show the information for the atlanta site.
