Are you running Hybrid (CatOS on the switch and IOS on the MSFC) or
Native IOS? I know for Native IOS, Cisco is s'posed to make a newer IOS
that has a 2-3 second failover, but as far as I know, they haven't done
that yet and you still have that 40-60 second period where the failover
Sup has to re-initialize all of the cards again (and you lose all of
your state information for things like NAT, IOS Server Load Balancing,
etc)

Subject: Fast Software Upgrade in 6500
Hi all:
Anyone has tried the native IOS FSU feature in a 6500?.
If I'm not wrong, when you have 2 supervisors and RPR+ configured in
your Catalyst 6500 (this is my case) you can use this feature to upgrade
the IOS version "without rebooting" the switch. I've tried it, by i'm
seeing that i ever have a period of 48 seconds of outage (when i execute
the "redundancy force-switchover" command).
I though the RPR+ mode provided a better switchover time. Anyone can
tell me if this is normal or maybe i haven't configured this redundancy
mode properly? I'm using 12.1.13E5 and upgrading to 12.1.13E6. I have
Supervisors IA with MSFC2 and PFC.
