| Name | Data Type | Permissions | Description |
|---|---|---|---|
| name | <String> | Read-write | Name for the GSLB virtual server. Must begin with an ASCII alphanumeric or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Can be changed after the virtual server is created. CLI Users: If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "my vserver" or my vserver).<br>Minimum length = 1 |
| servicetype | <String> | Read-write | Protocol used by services bound to the virtual server.<br>Possible values = HTTP, FTP, TCP, UDP, SSL, SSL_BRIDGE, SSL_TCP, NNTP, ANY, SIP_UDP, RADIUS, RDP, RTSP, MYSQL, MSSQL, ORACLE |
| iptype | <String> | Read-write | The IP type for this GSLB vserver.<br>Default value: IPV4<br>Possible values = IPV4, IPV6 |
| dnsrecordtype | <String> | Read-write | DNS record type to associate with the GSLB virtual servers domain name.<br>Default value: A<br>Possible values = A, AAAA, CNAME |

| backupsessiontimeout | <Double> | Read-write | A non zero value enables the feature whose minimum value is 2 minutes. The feature can be disabled by setting the value to zero. The created session is in effect for a specific client per domain.<br>Minimum value = 0<br>Maximum value = 1440 |
| backuplbmethod | <String> | Read-write | Backup load balancing method. Becomes operational if the primary load balancing method fails or cannot be used. Valid only if the primary method is based on either round-trip time (RTT) or static proximity.<br>Possible values = ROUNDROBIN, LEASTCONNECTION, LEASTRESPONSETIME, SOURCEIPHASH, LEASTBANDWIDTH, LEASTPACKETS, STATICPROXIMITY, RTT, CUSTOMLOAD |
| netmask | <String> | Read-write | IPv4 network mask for use in the SOURCEIPHASH load balancing method.<br>Minimum length = 1 |
| v6netmasklen | <Double> | Read-write | Number of bits to consider, in an IPv6 source IP address, for creating the hash that is required by the SOURCEIPHASH load balancing method.<br>Default value: 128<br>Minimum value = 1<br>Maximum value = 128 |
| tolerance | <Double> | Read-write | Site selection tolerance, in milliseconds, for implementing the RTT load balancing method. If a sites RTT deviates from the lowest RTT by more than the specified tolerance, the site is not considered when the NetScaler appliance makes a GSLB decision. The appliance implements the round robin method of global server load balancing between sites whose RTT values are within the specified tolerance. If the tolerance is 0 (zero), the appliance always sends clients the IP address of the site with the lowest RTT.<br>Minimum value = 0<br>Maximum value = 100 |
| persistencetype | <String> | Read-write | Use source IP address based persistence for the virtual server. After the load balancing method selects a service for the first packet, the IP address received in response to the DNS query is used for subsequent requests from the same client.<br>Possible values = SOURCEIP, NONE |
| persistenceid | <Double> | Read-write | The persistence ID for the GSLB virtual server. The ID is a positive integer that enables GSLB sites to identify the GSLB virtual server, and is required if source IP address based or spill over based persistence is enabled on the virtual server.<br>Minimum value = 0<br>Maximum value = 65535 |

| disableprimaryondown | <String> | Read-write | Continue to direct traffic to the backup chain even after the primary GSLB virtual server returns to the UP state. Used when spillover is configured for the virtual server.<br>Default value: DISABLED<br>Possible values = ENABLED, DISABLED |
| dynamicweight | <String> | Read-write | Specify if the appliance should consider the service count, service weights, or ignore both when using weight-based load balancing methods. The state of the number of services bound to the virtual server help the appliance to select the service.<br>Default value: DISABLED<br>Possible values = SERVICECOUNT, SERVICEWEIGHT, DISABLED |
| state | <String> | Read-write | State of the GSLB virtual server.<br>Default value: ENABLED<br>Possible values = ENABLED, DISABLED |
| considereffectivestate | <String> | Read-write | If the primary state of all bound GSLB services is DOWN, consider the effective states of all the GSLB services, obtained through the Metrics Exchange Protocol (MEP), when determining the state of the GSLB virtual server. To consider the effective state, set the parameter to STATE_ONLY. To disregard the effective state, set the parameter to NONE. The effective state of a GSLB service is the ability of the corresponding virtual server to serve traffic. The effective state of the load balancing virtual server, which is transferred to the GSLB service, is UP even if only one virtual server in the backup chain of virtual servers is in the UP state.<br>Default value: NONE<br>Possible values = NONE, STATE_ONLY |
| comment | <String> | Read-write | Any comments that you might want to associate with the GSLB virtual server. |
| somethod | <String> | Read-write | Type of threshold that, when exceeded, triggers spillover. Available settings function as follows: * CONNECTION - Spillover occurs when the number of client connections exceeds the threshold. * DYNAMICCONNECTION - Spillover occurs when the number of client connections at the GSLB virtual server exceeds the sum of the maximum client (Max Clients) settings for bound GSLB services. Do not specify a spillover threshold for this setting, because the threshold is implied by the Max Clients settings of the bound GSLB services. * BANDWIDTH - Spillover occurs when the bandwidth consumed by the GSLB virtual servers incoming and outgoing traffic exceeds the threshold. * HEALTH - Spillover occurs when the percentage of weights of the GSLB services that are UP drops below the threshold. For example, if services gslbSvc1, gslbSvc2, and gslbSvc3 are bound to a virtual server, with weights 1, 2, and 3, and the spillover threshold is 50%, spillover occurs if gslbSvc1 and gslbSvc3 or gslbSvc2 and gslbSvc3 transition to DOWN. * NONE - Spillover does not occur.<br>Possible values = CONNECTION, DYNAMICCONNECTION, BANDWIDTH, HEALTH, NONE |
| sopersistence | <String> | Read-write | If spillover occurs, maintain source IP address based persistence for both primary and backup GSLB virtual servers.<br>Default value: DISABLED<br>Possible values = ENABLED, DISABLED |

Some options that you can use for each operations:
Getting warnings in response: NITRO allows you to get warnings in an operation by specifying the "warning" query parameter as "yes". For example, to get warnings while connecting to the NetScaler appliance, the URL is as follows:
http://<netscaler-ip-address>/nitro/v1/config/login?warning=yes
If any, the warnings are displayed in the response payload with the HTTP code "209 X-NITRO-WARNING".
Authenticated access for individual NITRO operations: NITRO allows you to logon to the NetScaler appliance to perform individual operations. You can use this option instead of creating a NITRO session (using the login object) and then using that session to perform all operations,
To do this, you must specify the username and password in the request header of the NITRO request as follows:
X-NITRO-USER:<username>
X-NITRO-PASS:<password>
Note: In such cases, make sure that the request header DOES not include the following:
Cookie:NITRO_AUTH_TOKEN=<tokenvalue>
Note:
Mandatory parameters are marked in red and placeholder content is marked in <green>.
