Reporting Topology Changes in a Lower-Layer Network - Enabling the Devices in a SEP Segment to Process SmartLink Flush Packets

Context

When a host is connected to a SEP network using a SmartLink group, the host sends SmartLink Flush packets to inform the remote device in the SEP segment if devices in the SmartLink group experience an active/standby switchover. Therefore, devices in a SEP segment must be able to process SmartLink Flush packets.

Procedure

Run system-view
The system view is displayed.
Run sep segment segment-id
A SEP segment is created and the view of the SEP segment is displayed.
Run deal smart-link-flush
The device in a SEP segment is configured to process SmartLink Flush packets.

By default, no device in a SEP segment is configured to process SmartLink Flush packets.
Run quit
Return to the system view.
Run interface interface-type interface-number
The interface view is displayed.
Run smart-link flush receive control-vlan vlan-id [ password { simple | sha } password ]
The interface is configured to receive Flush packets.

By default, an interface is prohibited from receiving Flush packets.

The password parameter is optional. If no password is specified, no password is used for authentication.

The control VLAN ID and password contained in Flush packets on both devices must be the same.
