EoS, EoL information about IOS are not listed in EoS Notice


Now, I'm searching information about a lot of IOS versions.

I'd like to know Release date, EoS and EoL date that are not listed in

End-of-Sale and End-of-Sale Notice.

For example, in case of CAT2950. Two major release IOS are exist.

One of them is 12.1EA, another one is 12.1AZ.

First version of 12.1EA is 12.1(11)EA1.

First version of 12.1AZ is 12.1(14)AZ.

These versions are already EoS and listed in the below URL.

Cisco IOS Software Releases 12.1 Special and Early Deployments

End-of-Sale Releases


But I could not find EoS, EoL date information for these IOS.

And other Early Deplotment version too.

How can I find the EoS date?

Hello Kanae,

if your service contract isn't expired you can upgrade to a later release without additional fee.

This is a common policy and it is pushed by Cisco itself.

I would suggest to move to 12.1.22EA10


Hope to help
