Summary of ERPS Configuration Tasks
This section describes ERPS features supported by the NetEngine 8000 F.
ERPS is a protocol defined by the ITU-T to block specified ports to prevent Layer 2 loops.
The ERPSv1 configuration roadmap is as follows:
- Create an ERPS ring, configure the control VLAN and ERP instance, add ports to the rings, and specify port roles. These ERPS configurations help break loops.
- Configure the WTR timer and guard timer for the ERPS ring according to real-world situations.
- Associate ERPS with a fault detection protocol to shorten the traffic interruption time.
The ERPSv2 configuration roadmap is as follows:
- Create ERPS rings, configure control VLANs and ERP instances for the rings, specify ERPSv2, specify major rings and sub-rings, add ports, and specify port roles. These ERPS configurations help break loops.
- Configure the topology change notification function to ensure traffic transmission according to real-world situations.
- Configure ERPS revertive or non-revertive switching, forced switch (FS) or manual switch (MS), or timers according to real-world situations.
- Associate ERPS with a fault detection protocol to shorten the traffic interruption time.
ERPSv1 and ERPSv2 are currently available. ERPSv2, compatible with ERPSv1, supports multi-ring topologies and association with connectivity fault management (CFM), in addition to ERPSv1 functions, such as single ring topologies and multi-instance.
