Configuring IP Multicast Layer 3 Switching
This example shows how to enable the hardware shortcut-consistency checker:
Router (config)# mls ip multicast consistency-check
Router (config)#
Configuring ACL-Based Filtering of RPF Failures
When you configure ACL-based filtering of RPF failures, ACLs that filter RPF failures in hardware are
downloaded to the hardware-based ACL engine and applied on the interface you specify.
To enable ACL-based filtering of RPF failures on an interface, perform this task:
Command
Step 1
Router(config)# interface {{vlan vlan_ID} |
1
{type
slot/port} | {port-channel number}}
Step 2
Router(config-if)# mls ip multicast stub
Router(config-if)# no mls ip multicast stub
1.
type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Displaying RPF Failure Rate-Limiting Information
To display RPF failure rate-limiting information, perform this task:
Command
Router# show mls ip multicast summary
This example shows how to display RPF failure rate-limiting information:
Router# show mls ip multicast summary
10004 MMLS entries using 1280464 bytes of memory
Number of partial hardware-switched flows:4
Number of complete hardware-switched flows:10000
Router#
Displaying IP Multicast Layer 3 Hardware Switching Summary
The show interface statistics command does not display hardware-switched packets, only packets
Note
switched by software.
The show ip pim interface count command displays the IP multicast Layer 3 switching enable state on
IP PIM interfaces and the number of packets received and sent on the interface.
