difference

Description: Specify the round-delay-time difference.

Type: number

Range: 0-16383

Default: 0

enable

Description: When you enable aRDT, a site ACOS device sends some DNS requests to the GSLB domain’s local DNS. The GSLB ACOS device then averages the aRDT times of 5 samples.

Type: boolean

Supported Values: true, false, 1, 0

Default: 0

fail-break

Description: Enables GSLB to stop if the configured aRDT limit in a policy is reached.

Type: boolean

Supported Values: true, false, 1, 0

Default: 0

ignore-id

Description: Excludes the IP addresses in the specified IP list from aRDT data collection.

Type: number

Range: 0-31

keep-tracking

Description: Continues tracking of aRDT for clients after the track time expires.

Type: boolean

Supported Values: true, false, 1, 0

Default: 0

limit

Description: Specifies the aRDT limit for the policy. This option is useful for applying site selection based on aRDT limits and geo-location.

Type: number

Range: 1-16383

Default: 16383

samples

Description: Specify the number of samples to collect.

Type: number

Range: 1-8

Default: 5

single-shot

Description: Take a single sample and use that sample indefinitely. This option instructs each site ACOS device to send a single DNS query to the GSLB local DNS. Using the single-shot option ensures that clients are not frequently sent to differing sites based on aRDT measurements.

Type: boolean

Supported Values: true, false, 1, 0

Default: 0

skip

Description: Specifies the number of site ACOS devices that can exceed their single-shot timeouts, without the aRDT metric itself being skipped by the GSLB ACOS device during site selection.

Type: number

Range: 1-31

Default: 3

timeout

Description: Specifies the number of seconds each site ACOS device should wait for the DNS reply. If the reply does not arrive within the specified timeout, the site becomes ineligible for selection, in cases where selection is based on the aRDT metric.

Type: number

Range: 1-255

Default: 3

tolerance

Description: Specifies how much the aRDT values must differ in order for GSLB to prefer one geolocation or site over another based on aRDT.

Type: number

Range: 0-100

Default: 10

uuid

Description: uuid of the object

Type: string
