ERPS Settings

ERPS (Ethernet Ring Protection Switching) is the first industry standard (ITU-T G.8032) for Ethernet ring protection
switching. 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

Description
The VLAN to which the specified filtering action applies. Tick the All check box 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 All Groups – This will instruct the Switch to forward all multicast packets to
the specified VLAN.
Forward Unregistered Groups – The multicast packets whose destination is an
unregistered multicast group will be forwarded within the range of ports specified
above.
Filter Unregistered Groups – The multicast packets whose destination is a
registered multicast group will be forwarded within the range of ports specified
above.
