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.
