The deal smart-link-flush command enables a device in a SEP segment to process SmartLink Flush packets.
The undo deal smart-link-flush command disables a device in a SEP segment from processing SmartLink Flush packets.
By default, a device in a SEP segment is disabled from processing SmartLink Flush packets.
Usage Scenario
When a host is connected to a SEP network through a SmartLink group, the host sends SmartLink Flush packets to the connected devices in the SEP segment, if the active/standby switchover of member interfaces in the SmartLink group occurs. In this situation, the deal smart-link-flush command must be used to enable the devices in the SEP segment to process SmartLink Flush packets.
Prerequisites
Interfaces have been added to the SEP segment.
Precautions
After the deal smart-link-flush command is used, the device that receives a SmartLink Flush packet in the SEP segment floods the forwarding database (FDB) to notify the other devices in the SEP segment of topology changes. The other devices then refresh their MAC address entries to ensure reliable traffic transmission.
The deal smart-link-flush command must be run on the device that receives SmartLink Flush packets and the interfaces on the device have been added to the SEP segment.
