smart-link flush send

Function

The smart-link flush send vlan command enables the active interface in an Eth-Trunk interface in manual 1:1 master/backup mode to send Smart Link Flush packets.

The undo smart-link flush send command disables the active interface in an Eth-Trunk interface in manual 1:1 master/backup mode from sending Smart Link Flush packets.

By default, the active interface in an Eth-Trunk interface in manual 1:1 master/backup mode is disabled from sending Smart Link Flush packets.

Usage Guidelines

Usage Scenario

When intermediate devices exist between Eth-Trunk interfaces in manual 1:1 master/backup mode at both ends of an Eth-Trunk link and the active and inactive interfaces are switched in one Eth-Trunk interface, to allow the other Eth-Trunk interface to detect the switching, you must run the smart-link flush send command on the Eth-Trunk interfaces at both ends to enable the active interfaces to send Smart Link Flush packets, and run the smart-link flush enable control-vlan vlan-id command in the view of the intermediate devices' interfaces that connect to the Eth-Trunk interfaces at both ends of the Eth-Trunk link as well as the intermediate devices' interfaces that connect each other to enable the interfaces to receive Smart Link Flush packets. The exchange of Smart Link Flush packets helps update MAC and ARP entries.

Prerequisites

An Eth-Trunk interface in manual 1:1 master/backup mode has been created.

Example

# Enable the active interface in Eth-Trunk 1 to send Smart Link Flush packets.

[~HUAWEI] interface eth-trunk 1
[*HUAWEI-Eth-Trunk1] portswitch
[*HUAWEI-Eth-Trunk1] mode manual backup
