2.1.5 Clearing Multicast Forwarding and Routing Entries

To release system memory, you can use reset commands to clear multicast routing
entries, multicast forwarding entries, and related statistics information stored in the
device.
Follow these steps to clear the multicast-related entries and statistics:
Clear multicast forwarding
entries and, with
statistics specified, the
corresponding statistics
information
Clear routing entries in the
core multicast routing
table

2.1.6 Configuring a Multicast MAC Address Entry

In Layer 2 multicast, the system can add multicast forwarding entries dynamically
through a Layer 2 multicast protocol. Alternatively, you can statically bind a port to a
multicast MAC address entry by configuring a multicast MAC address entry manually.
Generally, when receiving a multicast packet for a multicast group not yet registered on
the switch, the switch will flood the packet within the VLAN to which the port belongs.
You can configure a static multicast MAC address entry to avoid this.
