Parameters
vlan-id:
Control VLAN ID, in the range of 1 to 4,094.
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.
Examples
# Configure to send flush messages within

Smart link group view
Parameters
group-id:
Link aggregation group ID, in the range of 1 to 464. Note that the specified
link aggregation group can only be a static or manual one.
master: Specifies
the specified link aggregation group as the master port of the smart link
group.
slave: Specifies
the specified link aggregation group as the slave port of the smart link group.
Description
Use the link-aggregation group
command to assign a link aggregation group to the smart link group.
Use the undo link-aggregation
group command to remove the specified link aggregation group from the 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.
Examples
# Configure link aggregation group 8 as the
slave port of smart link group 1.

Parameters
interface-type: Port type.
interface-number:

master: Specifies
the specified port as the master port of the smart link group.
slave: Specifies
the specified port as the slave port of the smart link group.
Description
Use the port command to assign the specified
port to the smart link group.
Use the undo port command to remove the
specified port from the smart link group.
The port you specified in this command
cannot be a link aggregation group member port.
Besides assigning single ports to a smart
link group, you can assign a link aggregation group (static or manual, but not
dynamic) to a smart link group with the link-aggregation group command
in smart link group view.
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.

Parameters
group-id:
Smart link group ID, in the range of 1 to 24.
master: Specifies
the port as the master port of the smart link group.
slave: Specifies
the port as the slave port of the smart link group.
Description
Use the port smart-link group
command to assign the current port to a smart link group.
Use the undo port smart-link group
command to remove the current port from the specified smart link group.
The port where you configure the command
cannot be a link aggregation group member port.
Besides assigning single ports to a smart
link group, you can assign a link aggregation group (static or manual, but not
dynamic) to a smart link group with the link-aggregation group command
in smart link group view.
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.

Parameters
vlan-id:
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 smart-link flush
enable command to disable the port from processing 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 commands: port smart-link group,
link-aggregation group, port.
Make sure that the smart
link group has no members before executing the undo smart-link group
command.

View
Monitor link group view
Parameters
group-id:
Link aggregation group ID, ranging from 1 to 464 (A link aggregation group can
be a manual or static link aggregation group only).
uplink: Specifies the specified link aggregation group as the uplink port of
the monitor link group
downlink:
Specifies 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.
Examples

Description
Use the monitor-link group command
to create a monitor link group and enter monitor link group view. If the monitor
link group has been created, you enter the monitor link group view directly.
Use the undo monitor-link group command
to remove a monitor link group.
After the monitor link group is configured,
member ports of the monitor link group need to be configured.
Related commands: port monitor-link
group, link-aggregation group, smart-link group, port.
Make sure that the monitor
link group has no members before executing the undo monitor-link group
command.
