Recommended Software on Cisco 4510R+E switch

ciscoworlds · ‎05-14-2019

Hi.

We're deploying ISE 2.4 on a customer site where there are many Catalyst 4510R+E switches with Supervisor 7-E installed on them and a few WS-X4748-RJ45V+E line cards per each chassis.

As we encountered with many strange behaviors regarding dot1x on these switches, we have decided to upgrade the IOS-XE software on them. Currently all of them run IOS-XE 03.04.06.SG. I took a look at the software center on Cisco website but didn't managed to find a "recommended" or "golden"image there. So I need to know if any version on 4510R+E Sup-7 has been labeled as "recommended" or "golden"image.

regards;

Try the latest 3.8.X.
Make sure you read the Release Notes because upgrading to 3.8.X requires a ROMmon upgrade.

Hi;

I read the release note which said the ROM upgrade is needed for supervisor 8-E. The current switches have Sup-7 so there is no need for Rom upgrade I think based on the release notes.

Regarding the IOS-XE version, I didn't managed to find anything documented, so I would probably go with the version you said to see if those strange behaviors are eliminated.

tnx.

Release Notes states:

If you are upgrading to Cisco IOS XE Release 3.8.xE and using Supervisor Engine 7-E or 7L-E, you must use ROMMON version 15.0(1r)SG10 or a higher version (if available).

My recommendation is: If you're going to do an upgrade, ignore the "recommended minimum" version of 15.0(1r)SG10 and upgrade to whatever latest is being offered.

Hope this helps.
