Guidelines and recommendations for using this feature
We recommend that you observe the following guidelines when using this feature:
• The GSLB controller and ADX device Site functionality (remote or local) should not be
configured on the same ADX device.
• Domain IPs should be VIPs rather than real IP hosts to minimize the health-check load on the
GSLB controller.
• Anytime a Site ADX state is changed from optimized to non-optimized (or vise versa) you must
reload the controller.
• If the GSLB optimization feature is enabled on the GSLB controller, then it is recommended to
not enable SLB for other services (enabling other services can cause resource problems).
• The GSLB controller will support maximum of 2048 GSLB enabled VIPs from all site ADX
devices. You must ensure that maximum number of GSLB enabled VIPs received from all sites
does not exceed 2048.
• To reduce the CPU usage, especially when there are many zones and GSLB enabled VIPs
configured, the GSLB optimization features should be enabled on both the GSLB controller and
GSLB site ADX devices as described in
“Increased VIP support per site and reduced CPU usage
on GSLB controller” on page 102
• When a site ADX has more than 256 SLB VIPs the controller health-status interval should be
set to 5 seconds (default value) or longer.

Displaying site information
You can display the following site information:
• ADX device name and management IP address
• Site name (displayed only if you display information for all sites rather than an individual site)
• State of the GSLB protocol connection between GSLB ADX device and site ADX device
• Number of sessions in the ADX device’s session table
• The percentage of the total number of sessions the ADX device can maintain that are in use
• The percentage of the ADX device’s CPU that is actively engaged in SLB and other activities
• The numeric preference value for this site ADX device
• The geographic location of the ADX device
• The virtual IP addresses (VIPs) configured on the ADX device
To display information for the sites you have configured on the GSLB Brocade Virtual ADX, use
either of the following methods.
