(Optional) Configuring ERPS Protection Switching

To ensure that ERPS rings function normally when a node or link fails, configure revertive/non-revertive switching, port blocking mode, and timers.

Run erps ring ring-id

Run revertive { enable | disable }
The protection switching mode is specified.

By default, ERPS rings use revertive switching.
Run quit

Run interface interface-type interface-number

Run erps ring ring-id protect-switch { force | manual }
A port blocking mode is specified.

The ERPS ring specified by ring ring-id must be the one to which the port belongs.

To delete the specified port blocking mode, run the clear command in the ERPS ring view.
Run quit
Return to the system view.
