Hello Sukesh,

I'm not sure to have understood,

This is an IOS image that runs on a RSM for Catalyst 5000.

IOS version is 12.0(10)W5

the final (18a) means it is a rebuild the 18th rebuild with a sub-rebuild a.

This is typical of end of sales devices where the policy is to freeze the major version and to make only minor changes rebuilds as needed.

Hope to help

Giuseppe

Thanks that helps.

In your experience, how many devices in production will have this version all the way up to nth rebuild and sub-build
