z Enable LACP MAD detection on the dynamic aggregate interface
z Add member ports to the aggregation group.(also required on the intermediate device)
Follow these steps to enable LACP MAD detection:
To do… Use the command… Remarks
Enter system view system-view —
Enter Layer 2 aggregation port
view interface bridge-aggregation
interface-number
Required
The aggregation port here must
be a dynamic aggregation port.
Configure the aggregation group
to work in dynamic aggregation
mode
link-aggregation mode dynamic
Required
By default, an aggregation group
works in static aggregation
mode.
Enable LACP MAD detection mad enable
Required
Disabled by default.
You can configure this command
on a common aggregation
interface. However, since LACP
detection is dependent on the
LACP protocol, the configuration
is effective only on a dynamic
aggregation port. You should
make sure that the port is a
dynamic aggregation port.
Quit system view quit —
Enter the view of the port that
connects to the LACP MAD
detection link
interface interface-type
interface-number
—
Assign the port to the aggregation
group for LACP MAD detection
port link-aggregation group number Required
Use the same method to create a dynamic aggregation group on the intermediate device and add the
port that connects to the LACP MAD detection link on the device to the aggregation group.
Specifying the reserved ports
When the IRF virtual device handles a multi-active problem, it disables all service ports on the devices
in the recovery state by default. However, if some ports are reserved for some special usages (such as
the port for telnetting), you can configure them through command lines. For the IRF ports that are
reserved automatically, you do not need to configure them.
Follow these steps to specify the reserved ports:
