Table 1. Configure devices with DNS SRV recordConfigure devices with DNS SRV record.
Option tag	Description
WMS server (_WMS_MGMT, Type SRV, Protocol _tcp, Port number 443)	This record directs the device to the WMS URL. For example, wmsserver.acme.com, where wmsserver.acme.com is the qualified domain name of the server. NOTE:There is a known issue that https:// is required in the WMS server URL. If you do not use https://, the device cannot automatically check in to WMS.
WMS server (_WMS_MGMTV2, Type Text)	This record directs the device to a secure WMS server.
(Optional) WMS MQTT Server	This record directs the device to the WMS Push Notification server (PNS). For a private cloud installation, the device gets directed to the MQTT service on the WMS server. For example, wmsservername.domain.com:1883. NOTE:MQTT is optional for WMS 5.0 or later versions.
WMS Group Token (_WMS_GROUPTOKEN, Type Text)	This record is required to register the ThinOS device with WMS on public or private cloud. NOTE:Group Token is case-sensitive. However, it is optional for WMS 5.0 on prem-server.
WMS Group Token (_WMS_GROUPTOKENV2, Type Text)	This record directs the device to secure Group Registration Key for WMS.
WMS CA Validation (_WMS_CAVALIDATION, Type Text)	You can enable or disable the CA validation option if you are registering your devices with WMS on private cloud. By default, the CA validation is enabled in the public cloud. You can also disable the CA validation in the public cloud. Enter True, if you have imported the SSL certificates from a well-known authority for https communication between the client and the WMS server. Enter False, if you have not imported the SSL certificates from a well-known authority for https communication between the client and the WMS server. NOTE:CA Validation is optional for WMS 5.0 or later versions.
