IOS for switch IE-4010 15.2.4-EC2 vs 15.2.8E

[Ajit Pai]

Hi community,

I'm looking for people willing to share their experience regarding these IOS firmware version for the switch IE-4010:

1. 15.2.4-EC2 released in 2016
2. 15.2.8E released in 2021

At the moment the Cisco suggested relase is the 15.2.4-EC2 relased in 2016.

Why is there so much discrepancy between the two releases although they are different from a few minor changes?

Has anyone had experience installing the 15.2.8E, 2021 release?

Thank you, best regards,

I am not sure where you checked the cisco recommended IOS but if you check on software download page you will find 

15.2.7E2  as suggested one.

Also here is what ED and MD means:

Early Deployment (ED): These releases provide both new features and new platform support in addition to bug fixes.

Maintenance Deployment (MD): These releases are used to provide additional support for bug fixes and ongoing software maintenance.
