Table 2. Registering device by using DHCP option tags (continued)
Option Tag Description
Name—MQTT
Data Type—String
Code—166
Description—MQTT Server
This tag directs the device to the Wyse Management Suite Push Notification
server (PNS). For a private cloud installation, the device gets directed to the
MQTT service on the Wyse Management Suite server. For example,
wmsservername.domain.com:1883. WDA automatically fetches the
MQTT details when devices check in for the first time.
NOTE: MQTT is optional for Wyse Management Suite 2.0 and later
versions.
Name—CA Validation
Data Type—String
Code—167
Description—Certificate Authority
Validation
You can enable or disable CA validation option if you are registering your
devices with Wyse Management Suite on private cloud.
Enter True, if you have imported the SSL certificates from a well-known
authority for https communication between the client and the Wyse
Management Suite server.
Enter False, if you have not imported the SSL certificates from a well-known
authority for https com@Wedding2020munication between the client and the
Wyse Management Suite server.
NOTE: CA Validation is optional for the latest version of Wyse
Management Suite 2.0 and later versions. However, it is recommended to
configure this option tag.
Name—Group Registration Key
Data Type—String
Code—199
Description—Group Registration Key
This tag directs to the Group Registration Key for the Wyse Management Suite
agent.
NOTE: Group Token is optional for Wyse Management Suite 2.0 and later
versions on private cloud. However, there is a known issue that if you do
not provide the group token, the device is not moved to unmanaged group.
Therefore, It is recommended to configure the Group Token key.

This section describes WMS Server, MQTT, Group Token, and CA Validation User-Defined Options defined using a DNS service.
Table 3. Configuring devices by using DNS SRV record

wmsserver.acme.com, where wmsserver.acme.com is the qualified domain name of
the server.
(Optional) WMS MQTT Server This record directs the device to the Wyse Management Suite Push Notification
server (PNS). For a private cloud installation, the device gets directed to the MQTT

a policy group.
