Usage Guidelines

Usage Scenario

ERPSv1 and ERPSv2 are currently available. ERPSv2, fully compatible with ERPSv1, provides the following enhanced functions:

Supports multi-ring topologies, such as intersecting rings.
Supports ring auto protection switching protocol data unit (R-APS PDU) transmission modes on sub-rings.
Supports two manual port blocking modes: forced switch (FS) and manual switch (MS).
Supports both revertive and non-revertive switching.
To configure an ERPS version, run the version command.

Precautions

Before specifying ERPSv1 for an ERPSv2-running device, delete all ERPS configurations that ERPSv1 does not support. Otherwise, the version cannot be changed.

Example

# Specify ERPSv2 for ERPS ring 5.

<HUAWEI> system-view
[~HUAWEI] erps ring 5
[*HUAWEI-erps-ring5] version v2
