ERPS DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide This window is used to display and configure the Ethernet Ring Protection Switching (ERPS) settings. STP and Loopback Detection (LBD) should be disabled on the ring ports before enabling ERPS. The ERPS cannot be enabled before the R-APS VLAN ring ports, RPL port, and RPL owner are configured. NOTE: Be aware that changing the ERPS version will lead to the restart of the running protocol. To view the following window, click L2 Features > ERPS (G.8032) > ERPS, as shown below: Figure 5-55 ERPS Window The fields that can be configured in ERPS Version Settings are described below: Parameter ERPS Version Description Select the ERPS version here. Options to choose from are G.8032v1 and G.8032v2. G.8032v2 provides the following functions: • Supports multi-instance in a physical ring. • Supports operation commands: manual, force, and clear. • Supports to configure the sending of the R-APS PDU destination address with the RING-ID of the physical ring. Before specifying G.8032v1 for a G.8032v2-running device, delete all ERPS configurations that G.8032v1 does not support. Otherwise, the version cannot be changed. Changing the ERPS version will lead to the restart of the running protocol. The following configurations will check when to change from G.8032v2 to G.8032v1: • Manual switch or force switch command will be cleared. • The major ring instance and sub-ring instance of the interconnection node must have different R-APS VLAN IDs. • In a physical ring, only one instance is supported. If Ethernet ring nodes running ITU-T G.8032v1 and ITU-T G.8032v2 co-exist on an Ethernet ring, the following configurations should be made on the G.8032v2 device: • All physical ring IDs must have the default value of 1. • The major ring instance and sub-ring instance of the interconnection node must have different R-APS VLAN IDs. 178
