Unless there is a good reason for doing so, do not change the default device class assignment for a particular device. This could cause your device communications to stop functioning properly.
-
Use the auto manage devices feature of device classes to automatically pull configurations, and store them in the repository when new devices come online and are made available.
-
Auto Manage is also a useful feature when you are adding a large, new network to your system, as it prevents you from having to manually manage every new device that is discovered, one-by-one.
-
If you have specific requirements that prohibit you from using specific protocols (such as, if you are disallowed from using TFTP within your network), use the Specify Protocols option to turn off all protocols that violate that requirement.
-
If you are running your Device Server and devices over a non-secure network, consider disabling all non-encrypted protocols to preserve the security of your communications stream. This would include turning off SNMP, Telnet, TFTP, and FTP as communications protocols, and relying instead on protocols such as SSH and SCP.
