Figure 4-106 Multicast Filtering Mode window
The fields that can be configured are described below:
Parameter Description
VLAN Name / VID List The VLAN to which the specified filtering action applies. Tick the All check box to
apply this feature to all the VLANs.
Multicast Filtering
Mode
This drop-down menu allows you to select the action that the Switch will take when
it receives a multicast packet that requires forwarding to a port in the specified
VLAN.
Forward All Groups - Both the registered group and the unregistered group will be
forwarded to all member ports of the specified VLAN where the multicast traffic
comes in.
Forward Unregistered Groups - The unregistered group will be forwarded to all
member ports of the VLAN where the multicast traffic comes in.
Filter Unregistered Groups - The unregistered group will be filtered.

ERPS Settings (RI and EI Mode Only)
Ethernet Ring Protection Switching (ERPS) is the first industry standard (ITU-T G.8032) for ERPS. It is achieved by
integrating mature Ethernet operations, administration, and maintenance (OAM) * functions and a simple automatic
protection switching (APS) protocol for Ethernet ring networks. ERPS provides sub-50ms protection for Ethernet
traffic in a ring topology. It ensures that there are no loops formed at the Ethernet layer.
One link within a ring will be blocked to avoid Loop (RPL, Ring Protection Link). When the failure happens,
protection switching blocks the failed link and unblocks the RPL. When the failure clears, protection switching
blocks the RPL again and unblocks the link on which the failure is cleared.
G.8032 Terms and Concepts
RPL (Ring Protection Link) – Link designated by mechanism that is blocked during Idle state to prevent loop on
Bridged ring
RPL Owner – Node connected to RPL that blocks traffic on RPL during Idle state and unblocks during Protected
state
R-APS (Ring – Automatic Protection Switching) - Protocol messages defined in Y.1731 and G.8032 used to
coordinate the protection actions over the ring through RAPS VLAN (R-APS Channel).
RAPS VLAN (R-APS Channel) – A separate ring-wide VLAN for transmission of R-APS messages
Protected VLAN – The service traffic VLANs for transmission of normal network traffic
This window is used to enable the ERPS function on the switch. EEE and ERPS are mutually exclusive functions.
NOTE: STP and LBD should be disabled on the ring ports before enabling ERPS. The ERPS cannot
be enabled before the R-APS VLAN is created, and ring ports, RPL port, RPL owner, are configured.
