The TP-Link switch crashes when The Dude Client starts exploring the network. Only the T2600G-28TS switch will collapse within 1 minute of the start of the client. When I stop the Dude client, the switch will not reset after the physical shutdown. When the switch crashes, it can not be accessed either on http or console port, the first time the client's screen will be green, then yellow and red will be the icon of the device. Other TP-Link devices will not collapse or become inaccessible.

What's the problem, what do I do to keep my tools from getting used to and using the Dude client?

Thanks for all your answers!

Client version: 6.43.2
Server: CHR-6.42.9.vdi on VirtualBox

Maybe it cannot withstand the SNMP requesting. Try to upgrade its software and check with tp-link support what to do next.
