I have a customer in trouble with NetSight's PM (java client) port information with legacy Enterasys gear (A2/B2/E1)...
Even being unsupported (EOSL), these devices still running on the customer site and after the upgrade of the NS from version 6.3 to the version 188.8.131.52 the issues arised.
On 6.3 when the customer tries to config ports on the "Details View" or "Ports" tabs, on these devices sometimes it shows no ports, sometimes it shows only ports from 12 to 24 (or 48), and even more oddly, sometimes it works fine. Even a refresh or restart the application doesn't solve the problem in many cases.
Other issue is on the "Port Usage" tab... The same behavior is shown... Sometimes it shows about the second half of the port's (12 and beyond) authenticated ports, sometimes it doesn't return any information and sometimes it works fine...
It used to work on the 6.3 version, but after the upgrade we are having problems with it.
