Information
This features allows the user 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 will only install the maximum possible number of entries, depending on the configured CAM
profile.
The IN-L3-McastFib CAM partition is used to store multicast routes and is a separate hardware limit
that is 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 Any software-configured limit might be superseded by this hardware space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 is reached.
