Does CoPP actuaally work now?

We've been bitten by the RPQ issue many times.  ARP and routing protocols should now be split across two different CPU queues as of 15.5(3)S2.

In the mean time, you can use this to allocate more resources to that queue to prevent the routing protocols from going away during an ARP storm:
