Configuring MAD
Restrictions and guidelines for MAD configuration
Assigning IRF domain IDs
An IRF fabric has only one IRF domain ID.
You can change the IRF domain ID by using the
irf domain
or
mad enable
command. The IRF
domain IDs configured by using the commands overwrite each other.
If LACP MAD runs between two IRF fabrics, assign each fabric a unique IRF domain ID. (For BFD
MAD, this task is optional.)
Actions on interfaces shut down by MAD
To prevent a multi-active collision from causing network issues, avoid using the
undo shutdown
command to bring up the interfaces shut down by a MAD mechanism on a Recovery-state IRF
fabric.
Configuring LACP MAD
1.
Enter system view.
system-view
2.
Assign a domain ID to the IRF fabric.
irf domain domain-id
The default IRF domain ID is 0.
3.
Create an aggregate interface and enter aggregate interface view.
Enter Layer 2 aggregate interface view.
interface bridge-aggregation interface-number
Enter Layer 3 aggregate interface view.
interface route-aggregation interface-number
Perform this step also on the intermediate device.
4.
Configure the aggregation group to operate in dynamic aggregation mode.
link-aggregation mode dynamic
By default, an aggregation group operates in static aggregation mode.
LACP MAD takes effect only on dynamic aggregate interfaces.
Perform this step also on the intermediate device.
5.
Enable LACP MAD.
mad enable
By default, LACP MAD is disabled.
6.
Return to system view.
quit
7.
Enter Ethernet interface view or interface range view.
Enter Ethernet interface view.
interface interface-type interface-number
Enter interface range view. Choose one of the following commands:
interface range
{
interface-type interface-number
[
to
interface-type interface-number
]
}
