Configuring Acl-Based Filtering Of Rpf Failures; Displaying Rpf Failure Rate-Limiting Information - Cisco WS-SUP32-GE-3B - Supervisor Engine 32 Software Configuration Manual

Chapter 25 Configuring IPv4 Multicast Layer 3 Switching
If consistency checking is enabled, the multicast route table will be scanned every two seconds and a full
scan is completed within 4 mintues.
To enable shortcut-consistency checking, perform this task:
Command
Router(config)# mls ip multicast consistency-check
Router(config)# no mls ip multicast consistency-check num
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
