IP Multicast Layer 3 Switching
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.
IP PIM interfaces and the number of packets received and sent on the interface.
Note
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:
