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.
