Using storm control for 10 Gig uplinks in datacenter?

Hi all, I have a question to storm control on 4500X switches. In a customer environment ports get blocking with a configured level of 0.01%. Is this one to low? Does anybody have experience with that feature on 10 Gig links.

New appended - Yes - my question is related to uplinks as there are a Blade system (Flex system ) is connected to and there are some notes with running VM on it. 

Thanks Bernd

That's 1 Mbit of broadcast traffic. I wouldn't expect to see more than that on a 10 Gbps port. Is the command available in PPS on the platform as well?

It's difficult to find an optimal setting without running tests how much the platform can handle but I'd rather lose a few ARPs than having the whole box go down.

In my humble opinion, you don't put storm control on the uplink (of any switch).  Storm control's place is on the access port.

Oh,

I missed to catch that in the topic. I would agree on that yes, to not use it on uplinks. For a user port 1 Mbit should be enough. The 4500x has a lot of 10GE so it wasn't obvious to me that this was an uplink.

Hi , it is also my opinien but not that from our client. So the question is, did any one already used it on uplinks and with which level.

Thanks Bernd

We never implemented storm control on the uplinks because it caused dropouts.  If we employ storm control on access ports, then the dropouts disappears. 

The client is reading documents dated ten years ago.
