gslb-parameter¶
The following operations can be performed on "gslb-parameter":
set gslb parameter¶
Sets various global GSLB parameters.
Synopsis¶
set gslb parameter [-ldnsEntryTimeout
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(0x2b4cb208)
dropLdnsReq Drop LDNS requests if round-trip time (RTT) information is not available.
Possible values: ENABLED, DISABLED Default value: DISABLED
GSLBSvcStateDelayTime Amount of delay in updating the state of GSLB service to DOWN when MEP goes down. This parameter is applicable only if monitors are not bound to GSLB services Default value: 0 Maximum value: 3600
SvcStateLearningTime Time (in seconds) within which local or child site services remain in learning phase. GSLB site will enter the learning phase after reboot, HA failover, Cluster GSLB owner node changes or MEP being enabled on local node. Backup parent (if configured) will selectively move the adopted children's GSLB services to learning phase when primary parent goes down. While a service is in learning period, remote site will not honour the state and stats got through MEP for that service. State can be learnt from health monitor if bound explicitly. Default value: 0 Maximum value: 3600
AutomaticConfigSync GSLB configuration will be synced automatically to remote gslb sites if enabled.
Possible values: ENABLED, DISABLED Default value: DISABLED
MEPKeepAliveTimeout Time duartion (in seconds) during which if no new packets received by Local gslb site from Remote gslb site then mark the MEP connection DOWN Default value: 10 Minimum value: 1
GSLBSyncInterval Time duartion (in seconds) for which the gslb sync process will wait before checking for config changes. Default value: 10 Minimum value: 1
GSLBSyncMode Mode in which configuration will be synced from master site to remote sites.
Possible values: IncrementalSync, FullSync Default value: IncrementalSync
GSLBSyncLocFiles If disabled, Location files will not be synced to the remote sites as part of automatic sync.
Possible values: ENABLED, DISABLED Default value: ENABLED
GslbConfigSyncMonitor If enabled, remote gslb site's rsync port will be monitored and site is considered for configuration sync only when the monitor is successful.
Possible values: ENABLED, DISABLED Default value: DISABLED
Example¶
set gslb parameter -ldnsMask 255.255.0.0
show gslb parameter¶
Displays the global GSLB parameters.
Synopsis¶

Arguments¶
Output¶
flags State of the GSLB parameter.
ldnsEntryTimeout Time, in seconds, after which an inactive LDNS entry is removed.

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.

ldnsProbeOrder The order in which monitors should be initiated to calculate RTT
dropLdnsReq Drop LDNS requests if round-trip time (RTT) information is not available.
GSLBSvcStateDelayTime Amount of delay in updating the state of GSLB service to DOWN when MEP goes down. This parameter is applicable only if monitors are not bound to GSLB services
SvcStateLearningTime Time (in seconds) within which local or child site services remain in learning phase.

Backup parent (if configured) will selectively move the adopted children's GSLB services to learning phase when primary parent goes down.

AutomaticConfigSync GSLB configuration will be synced automatically to remote gslb sites if enabled.
builtin feature The feature to be checked while applying this config
MEPKeepAliveTimeout Time duartion (in seconds) during which if no new packets received by Local gslb site from Remote gslb site then mark the MEP connection DOWN
GSLBSyncInterval Time duartion (in seconds) for which the gslb sync process will wait before checking for config changes.
GSLBSyncMode Mode in which configuration will be synced from master site to remote sites.
incarnation This is a counter to maintain the gslb sync incarnation number.
GSLBSyncLocFiles If disabled, Location files will not be synced to the remote sites as part of automatic sync.
GslbConfigSyncMonitor If enabled, remote gslb site's rsync port will be monitored and site is considered for configuration sync only when the monitor is successful.
Example¶
show gslb parameter
unset gslb parameter¶
Use this command to remove gslb parameter settings.Refer to the set gslb parameter command for meanings of the arguments.
