I got a 3750 switch and want to put it into production. However the version on the switch is quite old 12.1(19)EA1d .
I went to the cisco website and decided to take the latest version. So I found that they have now 12.2 packages available...However, at the end of the version they have now SEE, SEA, SED, SE. what is the right one of these pacakges? for example the packages are like 12.2(25)SED1 .
How do I know if this matches the feature set I had with my old version...?
