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.

Commands

show ip igmp groups — shows the IGMP groups.

ip multicast-routing

Enable IP multicast forwarding.
