2.3.4 (Optional) Setting the Forwarding Mode of Multicast Data in
a VLAN
Context
You can set the forwarding mode of multicast data so that the multicast flows can be forwarded
based on IP addresses or MAC addresses. When multicast IP addresses are mapped to MAC
addresses, up to 32 IP addresses can be mapped to one MAC address. Therefore, it is
recommended that multicast data be forwarded based on IP addresses; otherwise, unregistered
users may receive the multicast data.
CAUTION
Before setting the forwarding mode of multicast data in a VLAN, disable IGMP snooping in the
VLAN. After setting the forwarding mode, enable IGMP snooping in the VLAN for the
configuration to take effect.
Procedure
Step 1 Run:
