Hi Lamine,
AFAIK, the "storm-control" command affects packets going into the L2 port.
You may want to take note of the following:
When the rate of multicast traffic exceeds a set threshold, all incoming
traffic (broadcast, multicast, and unicast) is dropped until the level drops
below the threshold level. Only spanning-tree packets are forwarded. When
broadcast and unicast thresholds are exceeded, traffic is blocked for only
the type of traffic that exceeded the threshold.
IMHO, the "ip multicast rate-limit" command is applied at routed interface,
either inbound/outbound directions. It is a policing function (policed rate
specified in kbps). Other options include matching the groups or sources of
the multicast traffic.
Just my 2cents. Let's hear it from others.
Thank you.
B.Rgds,
Lim TS
