This frees Bridging Table resources for learning new MAC addresses. For more information, see Address Tables. VLAN-Aware MAC-Based Switching The device always performs VLAN-aware bridging. VLAN-aware bridges perform VLAN-based MAC address learning and forwarding. Frames addressed to a unknown destination MAC address are flooded to all ports of the relevant VLAN. This is a standard feature. MAC Multicast Support Multicast service is a service that enables one-to-many and many-to-many communication for information distribution. In Layer 2 Multicast service, a single frame is addressed to a specific Multicast address, from which copies of the frame are transmitted to the relevant ports. When Multicast groups are statically enabled, you can set the destination port of registered groups, as well as define the behavior of unregistered Multicast frames. For more information, see Network Administration: Multicast. Layer 2 Features IGMP Snooping Internet Group Management Protocol (IGMP) Snooping examines IGMP frame contents, when they are forwarded by the device from work stations to an upstream Multicast router. From the frame data, the device identifies work stations configured for Multicast sessions, and which Multicast routers are sending Multicast frames. The IGMP Querier simulates the behavior of a Multicast router. This enables snooping of the Layer 2 Multicast domain even if there is no Multicast router. For more information, see IGMP Snooping.

Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period, are aged
out. This frees Bridging Table resources for learning new MAC addresses.

Address Tables
.
VLAN-Aware MAC-Based Switching
The device always performs VLAN-aware bridging. VLAN-aware bridges
perform VLAN-based MAC address learning and forwarding. Frames
addressed to a unknown destination MAC address are flooded to all ports of
the relevant VLAN.
This is a standard feature.
MAC Multicast Support
Multicast service is a service that enables one-to-many and many-to-many
communication for information distribution. In Layer 2 Multicast service, a
single frame is addressed to a specific Multicast address, from which copies of
the frame are transmitted to the relevant ports. When Multicast groups are
statically enabled, you can set the destination port of registered groups, as
well as define the behavior of unregistered Multicast frames.

Network Administration: Multicast

Layer 2 Features
IGMP Snooping
Internet Group Management Protocol (IGMP) Snooping examines IGMP
frame contents, when they are forwarded by the device from work stations to
an upstream Multicast router. From the frame data, the device identifies work
stations configured for Multicast sessions, and which Multicast routers are
sending Multicast frames. The IGMP Querier simulates the behavior of a
Multicast router. This enables snooping of the Layer 2 Multicast domain even
if there is no Multicast router.
