NOTE: STP and LBD should be disabled on the ring ports before enabling ERPS. ERPS cannot be
enabled before the R-APS VLAN is created, and ring ports, RPL port, and RPL owner are
configured. Note that these parameters cannot be changed when ERPS is enabled.
To view this window, click L2 Features > ERPS Settings, as shown below:
Figure 4- 83 ERPS Settings window
The fields that can be configured are described below:
Parameter Description
ERPS State
Enable or disable the ERPS State.
ERPS Log
Enable or disable the ERPS Log.
ERPS Trap
Enable or disable the ERPS Trap.
R-APS VLAN (1-
4094)
Specify the VLAN which will be the R-APS VLAN. The R-APS VLAN ID, West Port, East port,
RPL Owner status, Ring MEL*, Protected VLAN, Hold Off Timer, Guard Time, and WTR Time
can be modified in the ERPS Settings (Edit) window.
* 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 and 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 or use the Find button to locate an existing
VLAN, and click the Apply button.
To access the ERPS Settings (Edit) window, create an R-APS VLAN entry on the top half of the ERPS Settings
window and then click the corresponding Detail Information link:
