I have several older 2950's running on my network. This one in particular became of interest to me because I couldn't set up SSH on it or enable any QoS features on it, so I did some research. What I found was there are basically 2 versions of the IOS, c2950-i6q4l2 or c2950-i6k2l2q4. I also read that the c2950-i6q4l2 IOS versions (like the one in the switch I am referring to) have both the SI and EI feature sets integrated, but the one that gets enabled is entirely dependent upon the switch model you are running it on. Did I understand this correctly? Does the IOS check the hardware on the switch and then decide with feature set to use? If so, what is prohibiting the EI feature set from being enabled on this switch? Is there a way to force the EI feature set to be enabled since it is integrated in this image? I pasted the sh ver output of the switch below.
