Volume 3-Layer 2 Configurations / Chapter 19-Ethernet Ring Protection Switching (ERPS) Relationship with other modules Step 3: Use the following command to check each DUT ERPS configuration R3. DGS-6600:15#show erps erpi ERPS global state : Enabled ERP instance #1 Domain name : erps Instance type : Major Instance state : Enabled Instance status : Idle R-APS controlled VLAN : 2 Ring MEL : 1 East ring port : eth2.6 East ring port state : Forwarding West ring port : eth2.5 West ring port state : Forwarding RPL owner port : (Not-configured) Service protected VLANs : 3 Guard timer : 500 milliseconds Hold-Off timer : 0 milliseconds WTR timer : 5 minutes Total ERP instances : 1 DGS-6600:15#show erps domain Domain ERPI Type Status Port-State ID erps 1 Major Idle East:Forwarding West:Forwarding Total ERPS domains : 1 Total ERP instances : 1 The same VLAN PC can ping each other. Unplug any link in the ring, for example, eth2.6 between R2 and R3, the original ERPS block port will become the forwarding within 50ms. Relationship with other modules Link Monitor module Each ERP instance should be registered on link monitor module, and the link monitor module will notify ERPS when the link failure or recovery event on ring ports is detected. Under this design specification for ERPS, the event may be notified from "Link Change (link-up or link-down)". FDB module When the ERP instance changes its topology, it will perform flush FDB action on ring ports. DGS-6600 Configuration Guide 191
