Advanced GSLB configuration for IPv6 2

Weighted site me tric 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.
You can disable this metric.
You can enable this metric and
assign weights to individual sites.
The weight can be from 0 to 100.
The default is 0.
Refer to “Weighted site m etric” on
page 211.
Session capacity threshold 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%.
You can disable this metric.
You can change the threshold to a
value from 0-100%.
Refer to “To view the results of
traffic distribution after configuring
weighted site metrics, use the show
gslob traffic site command. Refer to
“Displaying results of traffic
distribution for weighted sites” on
page 235.” on page 213.
Connection load Not supported. The connection load policy metric is
not supported in the current
implementation of GSLB for IPv6.
Active bindings 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.
You can enable and disable this
metric.
Refer to “Active bindings metric” on
page 214.
Round-trip time Not supported. The active and passive round-trip
time policy metrics are not
supported in the current
implementation of GSLB for IPv6.
Geographic location Enabled.
The GSLB controller selects an IP
address based on the geographic
location of the server.
You can disable this metric.
Refer to “Geographic location
metric” on page 216.
Available session capacity 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.
You can disable this metric.
You can change the tolerance to a
value from 0-100%.
Refer to “Available session capacity
metric” on page 218.
