IOS 15.0, or stick with 12.4?

mzinz

One of my main production routers is running 12.4(13r). We had to go back a few revs in order to clean up a couple bugs (EIGRP and CEF both had issues).

In order to get AnyConnect working, it looks like I need to be using 12.5(15) or newer.

Anyone tried IOS15? I'm wondering if I should try to find a late stable release of 12.4 or just move up to 15.

What router is this?

Specifically it is 12.4.15T or newer.

I'm using it on my home router but we're not using it yet in production. Too new. Too many odd bugs still. The last one I encountered was making it crash when trying the new SSH public key auth.

You'd have to get a late version of 12.4T not 12.4.

If you're going to use it for a production network then I'd say neither unless you absolutely need one of the new features introduced in 12.4T. If so then I'd go for 15.0 and hope you don't hit anything they introduced in 15.0 that wasn't in 12.4T
