hi, there can be the occasional bug or glitch - mainly (in our experience) due to new types of traffic on the network. our main downtimes are due to power outage (in excess of our UPS 6hr capability) and firmware updates.
however, you can help to negate any IOS issue by eg using dual supervisors in the 6500 platform, or by using eg s720-10G virtual router architecture. - or in the 3750 world, by having dual-homed stacks etc. ie use resiliency to work around any possible IOS/platform issues (this is true for any chosen network vendor!) of course, this then comes down to the classic 'if you run the same version on both boxes they'll get hit by the same bug' perennial question - I'm always happy to run a slightly newer version alongside the old trusted....and safeharbor is always a good option unless you cant use it (eg new a feature thats not in a safeharbor release!) alan _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
