I am planning to upgrade the IOS on my cisco 3750 switches and need some help to identify the correct version of software. At the moment I am using 12.2(35)SE5 and 12.2(50)SE1 on majority of the switches but 12.2 and 12.1 as well on some switches. I am confused while searching on the Cisco website. Could someone please advise if these IOS are EOS/EOL? I would appreciate if someone can please post any link or document of EOL table.
Also you can use the Cisco Security Advisories, Responses, and Notices to know more details about a specific software verision:
