we are using 12.2(18)SXE6b on a C6509 with a WS-SUP720-BASE supervisor. A Cisco engineer told us we should upgrade, as the image is deferred.
Using the software advisor, I cannot find an IOS compatible with the WS-SUP720-BASE, as it only gives me the WS-SUP720-3B as an option.
We are using SSH for mgmt. Other cards installed are WS-X6724-SFP and WS-X6704-10GE.
What IOS should I take?
many thanks in advance,
WS-SUP720-3B will be fine. Your Sup720 is probably that - the WS-SUP720-BASE is just what's written on the front panel. A show version will tell you the type of Supervisor.
You will _probably_ want to go to a 12.2(33)SXI code of the same feature type as your current (IP Base / IP Services or alike), but best to check in the Feature Navigator as well:
