Many of you are mentioning dual-homed customers, which of course is always an option. What I meant though is that it's very rare to find a set up where every single customer is dual-homed. So, in a "typical" deployment, do your line cards fail long before a SUP/RSP, or vice versa? For those that have dual SUPs/RSPs, has the second one been required *that* often?
I've seen a block of ports on an older 10/100 linecard drop; recovery came at next reboot. I've seen a 10/100 card die, and force a reload as it went down. Sup720s have been good to me. I think I've seen 1 or 2 backup Sups hiccup but come back to life.
More recently as a consultant, a customer's DC is showing one completely dead Sup (which forced an SSO event), one backup Sup that reloaded; out of ten units.
