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 configured CAM profile.
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-configured 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.
