On our network, we use many c6500 as access layer switches. Every user gets 1GB port. We decided to limit broadcasts on each port to 100 packets per second or so. We tried to do this with storm-control command, but the only option for threshold was setting port's maximum bandwidth (in percents %). There was no PPS option! The big problem is that the minimal threshold is 0.1% (simple math = 10Mbps). That threshold is enormous and useless against broadcast storms. The idea is to shut (err-disable) ports that start broadcast storms).
I know that other cisco switches such as c3560 do have the PPS threshold option. Does anyone know whether it can be done on c6500? Is it an IOS version issue? I've tryed to search for this feature on Cisco IOS navigator for 6500 and found NOTHING!
We want to limit the broadcasts on layer 2. NO ACLs!!!
