Hi! I am monitoring a Dell switch. Some ports where not assigned when I started monitoring it. I have deleted the free ports from the device. Now I have connected some new devices to the free ports and want to monitor them (the assigned ports), too. When I try to rediscover the deleted ports of my switch I don't get them. I click on "Rediscovery" and get an overview with all ports (included the deleted ones). The boxes for these ports are automatically checked. When I click "Add" the ports won't be added to the switch.
