Usage Guidelines

Usage Scenario

When the network is unstable or a faulty occurs on the device, traffic may switch between the primary and secondary PW. In this case, you need to run the stream-dual-receiving command to enable the secondary PW to receive and forward traffic from the peer. This reduces number of packets lost during switching.

Prerequisites

The master/slave mode has been configured as the PW redundancy mode.

Configuration Impact

The secondary PW can forward data but does not forward data before traffic is switched from the primary PW to the secondary PW.

Example

# Enable the secondary PW to receive and forward traffic from the peer.
