To do...
Enter system view
Enter Layer 2 aggregation port
view
Configure the aggregation
group to work in dynamic
aggregation mode
Enable LACP MAD detection
Quit system view
Enter the view of the port that
connects to the LACP MAD
detection link
Assign the port to the
aggregation group for LACP
MAD detection
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 system 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:
To do...
Enter system view
Use the command...
system-view
interface bridge-aggregation
interface-number
link-aggregation mode dynamic
mad enable
quit
interface interface-type
interface-number
port link-aggregation group
number
Use the command...
system-view
1-17
Remarks
—
Required
The aggregation port here
must be a dynamic
aggregation port.
Required
By default, an aggregation
group works in static
aggregation mode.
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.
