When I replace a (usually Cisco) switch (same name and address), I rediscover it in Orion and choose the ports I now want to monitor. Usually, the old switch is a C2960 100mb model, the new switch does not have any 100mb ports. This does not work for UDT. When I look at the node, one of the widgets displayed is the list of (UDT) monitored ports. It continues to display 100mb ports (i.e. Fa0/1, Fa0/2) that no longer exist. Short of deleting / readding the node, I don't know how I can clean it up.
