ERPS Settings
The first industry standard is called ITU-T G.8032 for Ethernet Ring Protection Switching (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 page is used to enable the ERPS function on the switch.
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. Note
that these parameters cannot be changed when ERPS is enabled.

Description
The VLAN to which the specified filtering action applies. Tick the All option to apply this
feature to all the VLANs.
This drop-down menu allows you to select the action the Switch will take when it receives
a multicast packet that requires forwarding to a port in the specified VLAN.
Forward Unregistered Groups – This will instruct the Switch to forward a multicast packet
whose destination is an unregistered multicast group residing within the range of ports
specified above.
Filter Unregistered Groups – This will instruct the Switch to filter any multicast packets
whose destination is an unregistered multicast group residing within the range of ports
specified above.
