I have to do an upgrade of my Catalyst 6509 at this moment I have a WS-X6K-SUP2-2GE and WS-F6K-MSFC2 and versions 6.1(1d) and 12.1(8a)E3. Memory RAM 128 FLASH 32.
Wich version will be better to make the upgrade? I will use this catalyst to do the intervalan routing of my LAN, we have about 2000 users.
thanks
