1.1.4 flush enable
Syntax
flush enable [ control-vlan id ]
undo flush enable
View
Smart link group view
Parameters
control-vlan id: Specifies a control VLAN ID, which ranges from 1 to 4094. If no VLAN is specified, VLAN 1 is used for the control VLAN.
Description
Use the flush enable command to enable flush message transmitting.
Use the flush enable control-vlan command to disable flush message transmitting.
By default, flush messages are transmitted in VLAN 1.
When the master link of a smart link group goes down, the device checks the slave link and unblocks it if the slave link is available. During the status transition, a smart link-enabled device communicates with the uplink devices through flush messages. If the uplink device can process the flush messages, the uplink device and the smart link device coordinate to choose links.
You need to enable flush message transmitting in control VLANs on uplink devices.
Caution:
VLANs of these types cannot be configured as control VLANs: VLANs dynamically learned through GVRP, super VLANs, sub-VLANs, isolate-user-VLANs, secondary VLANs, multicast VLANs, HGMP control VLANs, guest VLANs, and L2VPN-enabled VLANs.
& Note:
l Smart link groups used for load sharing must be configured with the same transmit control VLAN.
l The control VLAN of a smart link group must be mapped to a protected MSTI of the smart link group.
Related commands: smart-link flush enable.

Parameters
id: Link aggregation group ID, in the range 1 to 31, specifying a manual aggregation group.
master: Configures a link aggregation group as the master port of a smart link group.
slave: Configures a link aggregation group as the slave port of a smart link group.
Description
Use the link-aggregation group command to configure a manual aggregation group as the member of a smart link group.
Use the undo link-aggregation group command to remove a manual aggregation group from a smart link group.
& Note:
l On a port, smart link is mutually exclusive with STP, BPDU tunnel, and RRPP. Before configuring an aggregation group as a member of a smart link group, make sure STP or RRPP is disabled on the aggregation group. And after the configuration, you cannot enable STP or RRPP for the aggregation group either.
l To remove an aggregation group operating as a member of a smart link group, you need to remove it from the smart link group first.
l The member ports of an aggregation group cannot be configured as the member ports of the smart link group.
l The control VLAN of a smart link group cannot be the control VLAN or sub-VLAN of RRPP.
l You cannot configure a common spanning tree (CST) as the protected MSTI of any of the smart link groups that an aggregation group belongs to.
l To have an aggregation group assigned to load-sharing smart link groups share the traffic of the protected MSTI of a smart link group, you must configure the aggregation group as the master port of the smart link group.
An aggregation link group is down only when all the ports in it are down.

Smart link group view
Parameters
role: Configures the role preemption mode, which enables the master port to preempt the slave port in the active state.
Description
Use the preemption mode role command to enable the role preemption mode for the smart link group.
Use the undo preemption mode command to disable the preemption mode.
With role preemption enabled, the master port preempts the slave port to enter the active state if both of the ports are up.
With role preemption disabled, the master port in the standby state can enter the active state to forward traffic only when triggered by an event.
& Note:
You must enable role preemption mode for smart link groups used for load sharing.

1.1.9 protected-instance
Syntax
protected-instance instance-list
undo protected-instance [ instance-list ]
View
Smart link group view
Parameters
instance-list: Specifies MSTIs to be protected. You can provide up to 10 MSTI lists, by each of which you can specify an individual MSTI by its ID, or an MSTI range in the form of start-instance-id to end-instance-id, where the end MSTI ID must be greater than the start MSTI ID. The effective range of an MSTI ID is 0 to 48.
Description
Use the protected-instance command to configure the protected MSTIs for the smart link group. The port in the active state in the smart link group only forwards the traffic of the protected MSTIs.
Use the undo protected-instance command to remove the specified or all protected MSTIs of the smart link group.
& Note:
l By default, no protected MSTI is configured for a smart link group. Before assigning ports to a smart link group, configure protected MSTIs for the smart link group.
l You can remove all protected MSTIs from a smart link group when the group is empty but not after a member port is assigned to it.
l A common spanning tree (CST) cannot be configured as the protected MSTI of a smart link group used for load sharing.
l After a protected MSTI is removed from a smart link group, the smart link group does not manage the MSTI any more, exposing the MSTI to loop. To avoid the situation, you are recommended to remove the VLANs that the smart link group member ports belong to from the MSTI before removing the protected MSTI.
Examples
# Configure MSTIs 1 through 10 and MSTI 48 as the protected MSTIs of smart link group 1.

Parameters
id: Control VLAN ID, in the range 1 to 4094.
Description
Use the smart-link flush enable command to enable the port or the system to process flush messages received on the specified control VLAN.
Use the undo smart-link flush enable command to disable the port or the system from processing flush messages.
By default, a device does not process flush messages.
After an uplink device receives a flush message from the control VLAN, it deletes the specified MAC address entry based on the VLAN Bit Map in the flush message, and modifies the ARP table.

Smart link is developed to realize fast active-standby link switchover. STP convergence speed cannot satisfy some specific requirements. You can choose smart link instead.
A smart link group is composed of two member ports, the master port and the slave port. They can be single ports or manual aggregation groups. Each member port can either be in the active state or standby state. In a smart link group, up to one member can be in the active state.
& Note:
To use smart link for load sharing, you can create two smart link groups on the two load-sharing ports (single ports or aggregation groups).
