The following operations can be performed on “gslb-parameter”:

unset show set

unset gslb parameter

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

Synopsis

unset gslb parameter [-ldnsEntryTimeout] [-RTTTolerance] [-ldnsMask] [-v6ldnsmasklen] [-ldnsProbeOrder] [-dropLdnsReq] [-GSLBSvcStateDelayTime] [-SvcStateLearningTime] [-AutomaticConfigSync] [-MEPKeepAliveTimeout] [-GSLBSyncInterval] [-GSLBSyncMode] [-GSLBSyncLocFiles] [-GslbConfigSyncMonitor] [-GSLBSyncSaveConfigCommand] [-undefAction]

show gslb parameter

Displays the global GSLB parameters.

Synopsis

show gslb parameter

Arguments

Output

flags State of the GSLB parameter.

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

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.

ldnsMask The IPv4 network mask with which to create LDNS entries.

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.

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. 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.

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.

GSLBSyncSaveConfigCommand If enabled, ‘save ns config’ command will be treated as other GSLB commands and synced to GSLB nodes when auto gslb sync option is enabled.

undefAction Action to perform when policy evaluation creates an UNDEF condition. Available settings function as follows:

  • NOLBACTION - Does not consider LB action in making LB decision.
  • RESET - Reset the request and notify the user, so that the user can resend the request.
  • DROP - Drop the request without sending a response to the user.

overridePersistencyforOrder This option is used to override persistency when order is configured for services or servicegroups.

Example

show gslb parameter

set gslb parameter

Sets various global GSLB parameters.

Synopsis

set gslb parameter [-ldnsEntryTimeout ] \[-RTTTolerance ] \[-ldnsMask ] \[-v6ldnsmasklen <positive\_integer>] \[-ldnsProbeOrder ...] \[-dropLdnsReq \( ENABLED | DISABLED )] \[-GSLBSvcStateDelayTime ] \[-SvcStateLearningTime ] \[-AutomaticConfigSync \( ENABLED | DISABLED )] \[-MEPKeepAliveTimeout ] \[-GSLBSyncInterval ] \[-GSLBSyncMode \( IncrementalSync | FullSync )] \[-GSLBSyncLocFiles \( ENABLED | DISABLED )] \[-GslbConfigSyncMonitor \( ENABLED | DISABLED )] \[-GSLBSyncSaveConfigCommand \( ENABLED | DISABLED )] \[-undefAction ]

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(0x2be39640)

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.

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
