Usage Information This feature allows you to limit the number of multicast entries on the system. This number is the total of all
the multicast entries on all line cards in the system. On each line card, the multicast module only installs the
maximum number of entries, depending on the congured CAM prole.
To store multicast routes, use the IN-L3-McastFib CAM partition. It is a separate hardware limit that exists
per port-pipe. This hardware space limitation can supersede any software-congured limit. 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.
