2.2.4 Enabling the Sending of Flush Packets

Context
When the active and standby links of the Smart Link group switch, the existing forwarding
entries no longer apply to the new topology. All the MAC address entries and ARP entries on
the network need to be updated. Then the Smart Link group sends Flush packets to ask other
devices to update the MAC address table and ARP entries.
Because manufacturers define the format of Flush packets differently, the Flush packets
described here are used only for the intercommunication between Huawei S-series switches. In
addition, the function of receiving Flush packets must be enabled on the remote switch.
