IP receive access list
The IP receive access list feature uses IPv4 ACLs to filter the packets intended for the management
process to protect the management module from being overloaded with heavy traffic that was sent
to one of the Layer 3 Switch IP interfaces. The feature applies to IPv4 unicast and multicast
packets.
