The command results in an "IP-address not found for host-name" error if the IPv6 address
specified for the ip-weight parameter was not used as an argument when you defined the IP list.
For information about specifying IP lists, see
NOTE
If no IP list is defined for the host, the IP weight for the host IPs are removed from the GSLB DNS
zone configuration whenever the GSLB ServerIron ADX reloads.
Use the show gslb dns command to view information about the distribution of traffic after the
configuration of weighted IP metrics. For more informaiton see
page 237.
Weighted site metric
You can configure the ServerIron ADX to distribute SLB traffic among GSLB sites based on weights
configured for the sites. The weights determine the percentage of traffic each site will receive in
comparison with other sites, which may or may not have weights.
NOTE
You cannot use the weighted site metric if the weighted IP metric is enabled. You assign weights to
GSLB sites. Each GSLB site may consist of one or more ServerIron ADXs, but the weight is applicable
to the site as a whole.
The GSLB ServerIron ADX uses relative percentages in order to achieve 100% total weight
distribution.

The GSLB ServerIron ADX uses relative percentages in order to achieve 100% total weight
distribution, as shown in
site metrics (second column) is 100. The last column shows that the GSLB ServerIron ADX
distributes the traffic to the IP addresses exactly as configured. In this example, traffic distribution
is straightforward because the total weight of all three GSLB sites equals 100.

ServerIron ADX uses relative percentages in order to achieve 100% total weight distribution.
