Chapter 4 Adding Multicast MAC Address

4.1 Introduction

In Layer 2 multicast, you can not only dynamically create multicast forwarding entries
using the Layer 2 multicast protocol, but also set manually the multicast MAC address
and bind multicast entries to ports.
Generally, the packet is not broadcasted among the VLAN if its multicast address is not
registered on the local host. You can enable the broadcast, however, by configuring a
multicast static MAC address entry. Then the switch changes from dynamic multicast
learning to static multicast learning and saves the time originally to handle multicast
packets.
If you configure the switch not to forward unknown multicast packets (enabling the
unknown multicast blocked function), the switch cannot forward some specific multicast
packets (such as VRRP packets). You can enable to forward these types of packets by

adding multicast MAC address entries.

4.2 Adding Multicast MAC Address Entries
Follow these steps to add multicast MAC address entries:

If the multicast MAC address entry you intend to add has ex
the prompt information.
After you manually add a multicast MAC address, the switch cannot learn it using
IGMP snooping. The co
entries manually added, but not those learned by the switch.
