gslb parameter

Sep 12, 2016

The following operations can be performed on "gslb parameter":

set gslb parameter

Sets various global GSLB parameters.

Synopsys

set gslb parameter [-ldnsEntryTimeout <secs>] [-RTTTolerance <msecs>] [-ldnsMask <netmask>] [-v6ldnsmasklen <positive_integer>] [-ldnsProbeOrder <ldnsProbeOrder> ...] [-dropLdnsReq ( ENABLED | DISABLED )]

Arguments

ldnsEntryTimeout

Time, in seconds, after which an inactive LDNS entry is removed.

Default value: 180

Minimum value: 30

Maximum value: 65534

RTTTolerance

Tolerance, in milliseconds, for newly learned round-trip time (RTT) values. If the difference between the old RTT value and the newly computed RTT value is less than or equal to the specified tolerance value, the LDNS entry in the network metric table is not updated with the new RTT value. Prevents the exchange of metrics when variations in RTT values are negligible.

Default value: 5

Minimum value: 1

Maximum value: 100

ldnsMask

The IPv4 network mask with which to create LDNS entries.

Default value: 0xFFFFFFFF

v6ldnsmasklen

Mask for creating LDNS entries for IPv6 source addresses. The mask is defined as the number of leading bits to consider, in the source IP address, when creating an LDNS entry.

Default value: 128

Minimum value: 1

Maximum value: 128

ldnsProbeOrder

Order in which monitors should be initiated to calculate RTT.

Possible values: PING, DNS, TCP

Default value: ARRAY(0x2b635ce4)

dropLdnsReq

Drop LDNS requests if round-trip time (RTT) information is not available.

Possible values: ENABLED, DISABLED

Default value: DISABLED

Example

set gslb parameter -ldnsMask 255.255.0.0

unset gslb parameter

Use this command to remove gslb parameter settings.Refer to the set gslb parameter command for meanings of the arguments.

Synopsys

unset gslb parameter [-ldnsEntryTimeout] [-RTTTolerance] [-ldnsMask] [-v6ldnsmasklen] [-ldnsProbeOrder] [-dropLdnsReq]

show gslb parameter
