Command Syntax

Parameter

Parameter	Description

instance <instance-id>	Specifies the instance ID for a ring. The value is an integer that ranges from 1 to 2.

Usage Guidelines

When configuring this command, pay attention to the following notes:

The command erps switch force ring <ring-id> instance <instance-id> <port0 | port1> is an operational mode command which should be executed under the prompt “admin@PICOS>”.

ERPS supports two switching methods to manually configure port blocking:

Forced switch: Ports configured for forced switch are blocked immediately, regardless of whether other links on the ring are faulty or not.
Manual switch: Ports configured for manual switch are blocked if the state of the ring is Idle or Pending, otherwise they are not blocked.

The run show erps ring command can be used to show the node state of the ERPS ring instances. If force switch (or manual switch) is set successfully, the Node state in the show result displays Forced Switch (or Manual Switch).

The erps clear ring instance command can be used to clear the blocking point switching operation of the ERPS ring.

Example
