Make the port a routed port (= ingress packets go nowhere), set up
a SPAN session, find out what sort of packets are coming in (broacast,
multicast, unknown-unicast) and how many of them. Adjust limits,
as ytti said.
While I agree to "have storm-control anywhere" - if this is intended
to be a routed link, limits can be fairly high (the only reason why
you want storm-control is to protect the 4900M's CPU, not anything
else in the network).
OTOH, a 4900M? really?
