Verifying IP Multicast Layer 3 Hardware Switching Summary
The show ip pim interface count command verifies the IP multicast Layer 3 switching enable state on
IP PIM interfaces and the number of packets received and sent on the interface.
The show interface statistics command does not verify hardware-switched packets, only packets

switched by software.
Use the following show commands to verify IP multicast Layer 3 switching information for an IP PIM
Layer 3 interface, as illustrated below:
