I am going through a series of fixed configuration Cisco 3550 swtiches and upgrading their IOS versions. I can get most of the IOS's that I need off of the cisco site via the switch downloads section. The problem that I have run into is that I do not know what the upgrade path is for the IOS c3550-i5q3l2-mz.121-19.EA1c.
I have searched the internet in order confirm that the correct IOS version upgrade for this is c3550-ipservicesk9-mz.122-44.SE6.bin. I need to confirm, via some source, that the upgrade path for the IOS c3550-i5q3l2-mz.121-19.EA1c to c3550-ipservicesk9-mz.122-44.SE6.bin is correct. The hardware is WS-C3550-24-EMI.
If anyone has any sources on which IOS is the correct one for upgrading can you post that info? Thanks to everyone who reads this!!!
Fair enough, I suppose what I want to know is that I am not loosing any features by going to the IOS version that I mention. Without going through each feature is there a way to know which IOS version is comparable in features?
This is where Feature Navigator is really useful. Go to this page and then use the compare 2 features links to see what is available in both images -
