Configuring IPv4 Multicast Layer 3 Switching
Command
Router(config)# mls ip multicast connected
Router(config)# no mls ip multicast connected
This example shows how to enable installation of directly connected subnets:
Router(config)# mls ip multicast connected
Router(config)#

Specifying the Flow Statistics Message Interval

By default, the supervisor engine forwards flow statistics messages to the MSFC every 25 seconds. The
messages are forwarded in batches, and each batch of messages contains statistics for 25 percent of all
flows. If you leave the interval at the default of 25 seconds, it will take 100 seconds to forward statistics for
all flows to the MSFC.
To specify how often flow statistics messages forwarded from the supervisor engine to the MSFC,
perform this task:
Command
Router(config)# mls ip multicast flow-stat-timer num
Router(config)# no mls ip multicast flow-stat-timer num
This example shows how to configure the supervisor engine to forward flow statistics messages to the
MSFC every 10 seconds:
Router(config)# mls ip multicast flow-stat-timer 10
Router(config)#

Enabling Shortcut-Consistency Checking

When you enable the shortcut-consistency checking feature, the multicast route table and the
multicast-hardware entries are checked for consistency, and any inconsistencies are corrected. You can
view inconsistencies by entering the show mls ip multicast consistency-check command.
If consistency checking is enabled, the multicast route table will be scanned every two seconds and a full
scan is completed within 4 minutes.
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
