Configuring MAC Group Addresses
The
MAC Group Address
page enables you to view and configure associations
between multicast group MAC address and VLANs on the switch. You can
configure static associations or they can be learned dynamically through IGMP or
MLD snooping. When a packet is received for a multicast group address that
matches an entry in the MAC Group Address Table, the packet is sent only to ports
that are members of the VLAN.
The switch supports up to 256 IPv4 and IPv6 MAC group address table entries,
static and dynamic combined. A dynamic entry is aged out if no packets are
received for the MAC group address for a configurable time (see the
IGMP
Snooping
page to configure the IGMP Group Membership interval).
