Usage

This feature allows you to limit the number of multicast entries on the system. This

Information

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.
