Description
Use the flush enable control-vlan
command to enable the function of sending flush messages in the specified
control VLAN.
Use the undo flush enable control-vlan
command to disable the function of sending flush messages to the specified
control VLAN.
By default, no control VLAN is specified.

Smart Link group view
Parameter
group-id:
Link aggregation group ID, in the range of 1 to 28 (only link aggregation
groups configured manually or statically are available).
master:
Configures the specified link aggregation group as the master port of the Smart
Link group.
slave: Configures
the specified link aggregation group as the slave port of the Smart Link group.
Description
Use the link-aggregation group
command to configure a link aggregation group as a member of the Smart Link
group.
Use the undo link-aggregation
group command to remove the specified link aggregation group from the
current Smart Link group.
Because Smart Link
and STP cannot be enabled on an Ethernet port at the same time, you must make
sure that STP is disabled on the port before assigning the port to a smart link
group.
Example
# Configure link aggregation group 8 as the
slave port of Smart Link group 1.

Parameter
interface-type: Port type.
interface-number:

master:
Configures the specified port as the master port of the Smart Link group.
slave:
Configures the specified port as the slave port of the Smart Link group.
Description
Use the port command to configure
the specified port as a member of the Smart Link group.
Use the undo port command to remove the
specified port from the Smart Link group.
Either a single port or a link aggregation
group configured manually or statically can serve as a member for a Smart Link
group. However, a link aggregation group configured dynamically cannot serve as
a member for a Smart Link group. This command is not applicable to member ports
in a link aggregation group.
Because Smart Link
and STP cannot be enabled on an Ethernet port at the same time, you must make
sure that STP is disabled on the port before assigning the port to a smart link
group.

Description
Use the port smart-link group
command to configure the current port as a member of the Smart Link group.
Use the undo port smart-link group
command to remove the current port from the specified Smart Link group.
Either a single port or a link aggregation

Control VLAN ID, in the range of 1 to 4,094.
Description
Use the smart-link
flush enable control-vlan command to enable the current/specified port to
process flush messages received on the specified control VLAN.
Use the undo

flush messages.
l
The command executed in Ethernet port view has
effect on the current port only.
l
The command executed in system view has effect
on the specified port only.
By default, no control VLAN is specified.
If you configure different control VLANs on
the same port, only the last one takes effect.
The VLAN configured
as a control VLAN for sending or receiving flush messages must exist. You
cannot directly remove the control VLAN. When a dynamic VLAN is configured as a
control VLAN for the Smart Link group, this VLAN will become a static VLAN, and
related prompt information is displayed.

Use the undo smart-link group
command to remove the specified Smart Link group.
After creating a Smart Link group, you must
configure member ports for this Smart Link group.
Related command: port smart-link group,
link-aggregation group, and port.
Make sure that the Smart
Link group has no members before executing the undo smart-link group
command.

Parameter
group-id:
Link aggregation group ID, ranging from 1 to 28 (A link aggregation group can
be a manual or static link aggregation group only).
uplink: Configures the specified link aggregation group as the uplink port
of the Monitor Link group
downlink:
Configures the specified link aggregation group as
the downlink port of the Monitor Link group
Description
Use the link-aggregation group command
to configure the specified link aggregation group as a Monitor Link group
member.
Use the undo link-aggregation group command
to remove the specified link aggregation group from the current Monitor Link
group.
In Monitor Link, a Monitor Link group
member can be a single port, a manual or static link aggregation group, but not
a dynamic link aggregation group. Uplink port can also be a Smart Link group.
Use this command only on the link
aggregation groups that are not Smart Link group members.
A port or a link
aggregation group cannot serve as a member port for two Smart Link groups. On
the other hand, a port or a link aggregation group cannot serve as a member of
a Smart Link group and a Monitor Link group at the same time. However, a Smart
Link group can serve as the uplink member port of a Monitor Link group.
