GSLB policy metrics (Continued)for IPv6
Default
Disabled.
When the weighted IP metric is
enabled, the weighted site metric is
disabled. The weighted site metric is
an alternative to the weighted IP
metric. They are mutually exclusive.
When enabled, the ServerIron ADX
distributes SLB traffic among GSLB
sites based on weights configured
for the sites.
Enabled.
The default value for the threshold is
90%. Thus, a site ServerIron ADX is
eligible to be the best site only if its
session utilization is below 90%.
Not supported.
Disabled.
When enabled, the ServerIron ADX
selects an IP address with the
highest number of active bindings
as the best IP address for the client.
Not supported.
Enabled.
The GSLB controller selects an IP
address based on the geographic
location of the server.
Enabled.
The default tolerance is 10%.
When comparing sites based on the
session table utilization, the GSLB
ServerIron ADX will prefer one site
over the other only if the difference
in session table utilization is greater
than the tolerance percentage.

The weight can be from 0 to 100.
The default is 0.

You can disable this metric.
You can change the threshold to a
value from 0-100%.
Refer to
traffic distribution after configuring
weighted site metrics, use the show
gslob traffic site command. Refer to

distribution for weighted sites" on
page 235."
The connection load policy metric is
not supported in the current
implementation of GSLB for IPv6.
You can enable and disable this
metric.
