ERPS Settings

This page is used to enable the Ethernet Ring Protection Switching (ERPS) function on the Switch. 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.
To view this window, click L2 Features > ERPS Settings:
The fields that can be configured are described below:
Parameter
ERPS State
ERPS Log
ERPS Trap
R-APS VLAN
West Port
East Port
* If CFM (Connectivity Fault Management) and ERPS are used at the same time, the R-APS PDU is one of a suite of Ethernet OAM
PDU. The behavior for forwarding of R-APS PDU should follow the Ethernet OAM. If the MEL of R-APS PDU is not higher than the
level of the MEP (maintenance entity group end point) with the same VLAN on the ring ports, the R-APS PDU cannot be forwarded
on the ring.
Click Apply to implement changes apply the enable or disable state for ERPS, ERPS log and ERPS trap settings.
To create a new R-APS VLAN, enter the required settings in the window and click on the Create button.

Description
To enable or disable the ERPS State.
To enable or disable the ERPS Log.
To enable or disable the ERPS Trap.
Specify the VLAN which will be the R-APS VLAN. Enter the R-APS VLAN ID, West Port, East
port, RPL Owner status, Ring MEL*, Protected VLAN, Hold Off Timer, Guard Time, and WTR
Time.
Specifies the port as the west ring port. ERPS uses cardinal direction terms "East" and "West"
to designate how the ports on nodes in the ring are oriented to the ring itself. Each node on
the ring has an East port and West port. The West port of one node is linked to the East port
of the adjacent node in the ring.
Specifies the port as the east ring port. ERPS uses cardinal direction terms "East" and "West"
to designate how the ports on nodes in the ring are oriented to the ring itself. Each node on
the ring has an East port and West port. The East port of one node is linked to the West port
of the adjacent node in the ring.
