Hi Bro!
This is a very good question you’ve asked. Even I don’t know the correct answer. I don’t think many of us do, really. To my knowledge, Cisco doesn't publish those MTBF and MTTR values anymore in their product Data Sheet because these values can be misleading and misunderstood by clients.
However, the best way to seek this information is to speak directly to your local Cisco representatives, especially the Product Managers. They will know these accurate figures and are able to explain well.
However, as for me, what I normally tell my clients are, based the MTBF and MTTR value with Cisco’s EOS/EOL announcements. This is not accurate but can do :-)
Moving forward, to reduce your risk when it comes to MTBF and MTTR, you could always push this risk to your local Cisco Gold Partner with Maintenance Agreement signed-up.
P/S: If you think this comment is useful, please do rate them nicely :-)
Warm regards,
