At this moment I am installing 2 Cisco Catalyst 2960G-48TC-L switches with IOS 12.2(35)SE5 in an A330 aircraft instrumented for flight test.
I have noticed that it takes 3 minutes to start up the swiches, which is too much for my application. Therefore, I would like to reduce start-up time by means of disabling the POST, or at least taking it to the minimum.
POST process "PortASIC CAM Subsystem Tests" takes about 1:30 minutes to be done, which is 50% time consuming. So, I would like to disable this process and, if possible, any other unnecessary processes.
I don't need AFDX. I am using an standard Ethernet network. In the past I have used Catalyst 2950, which has done its job pretty well. Nevertheless, it is no longer supported so I purchased a 2960. I would like 2960 to start upas fast as 2950 did.

decision. To do this we require the switch to do...
