Typical failover time is about a minute. The redundancy mode is RPR http://www.cisco.com/warp/public/473/177.html

Re: Fail over time Catalyst 4507R - SUP iV

I haven't tested RPR on the 4507R, but I've done quite a bit of testing on supervisor failover on the 6500s. Since 4507R does only RPR, as opposed to RPR+ on the 6500, I'd expect failover to be slower.

Real-world failover for RPR+ on the 6500 is in the order of 60 seconds, which includes convergence on L2 and L3. When the 6500 is in RPR mode, the time is significantly higher. We're talking minutes.

But as I said: I haven't actually tested this on the 4507R, so I'd also be interested in any real-world experiences.
