By default, one port channel member is chosen to forward multicast traffic. With this feature turned on, multicast traffic is distributed among the port channel members in a round-robin fashion. This feature applies to the routed multicast traffic. If you turn on internet group management protocol (IGMP) snooping, this feature also applies to switched multicast traffic. ip multicast-limit - enables IP multicast forwarding. ip multicast-limit Use this feature to limit the number of multicast entries on the system. C-Series, E-Series, S-Series, Z-Series, S4810 Syntax Parameters ip multicast-limit limit limit Enter the desired maximum number of multicast entries on the system.

Usage Information This features allows you to limit the number of multicast entries on the system. This number is the sum total of all the multicast entries on all line cards in the system. On each line card, the multicast module only installs the maximum possible number of entries, depending on the configured CAM profile. Use the IN-L3-McastFib CAM partition to store multicast routes. It is a separate hardware limit that exists per port-pipe. Any software-configured limit might be superseded by this hardware space limitation. The opposite is also true, the CAM partition might not be exhausted at the time the system-wide route limit set by the ip multicast-limit command is reached. 1011
