set protocols erps tcn-propagation

The set protocols erps tcn-propagation command enables sub-ring topology change notifications. When the topology of the sub-ring changes, the FDB refresh of the port will generate a Topology Change (TC) signal. When the tcn-propagation function is enabled, the intersecting node sends an event flush message to the connect ring when it receives the TC signal.

The delete protocols erps tcn-propagation command disables sub-ring topology change notifications.

Command Syntax

set protocols erps tcn-propagation <true | false>

delete protocols erps tcn-propagation

Parameter

Usage Guidelines

To enable sub-ring topology change notifications, the following configurations are required:

1. Configure the connect ring for a sub-ring on all intersecting nodes.

set protocols erps ring <ring-id> instance <instance-id> connect ring <ring-id> instance <instance-id>

2. Enable tcn-propagation function to advertise topology changes to the connect ring on all intersecting nodes.

set protocols erps tcn-propagation <true | false>

Example

• Enable sub-ring topology change notifications.
