I am still using Optivity 8.1.1 and Nortel is no long support this product. It is always running ok to just manage the old bay stack devices. But today I get funny error. When I run ev against a baystack 150 hub, I got a pop-up window titled "Don't Panic", there is a sad face in the window and a line "Sorry. Internal Error" underneath. Anyone help. Thanks in advance!
