Nexus 7010 TCAM Over Utilization

Hi,

I guess I have reached a point where I have too many Vlans.  I created a few new ones and they are becoming errDisabled on various trunks (for some reason).  This, oddly, is only happening on one of the two vpc 7K peers.

My error is:

Tcam will be overused, pleaseturn off atomic update

Would a knowledgble engineer be able to give a decent description of what atomic ACL updates are?

What would the implicatiosn be of disabling atomic updates?

Is there a command that can show me what my TCAM utilization is and how I can know when it will be reached if I enable a new vlan?

Any insight would be much appreciated.

/r

Rob

Also like to mention this is only applicable to trunks on F-Series modules.
