Configuring LACP MAD
When you use LACP MAD, follow these guidelines:
The intermediate device must be a device that supports extended LACP for MAD.
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for correct split detection.
Use dynamic link aggregation mode. MAD is LACP dependent. Even though LACP MAD can be configured on both static and dynamic aggregate interfaces, it takes effect only on dynamic aggregate interfaces.
Configure link aggregation settings on the intermediate device.
To configure LACP MAD:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
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. |
| 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. 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 | N/A |
7. Enter Ethernet interface view or interface range view. |
| To assign a range of ports to the aggregation group, enter interface range view. To assign one port to the aggregation group, enter Ethernet interface view. |
8. Assign the Ethernet port or the range of Ethernet ports to the specified aggregation group. | port link-aggregation group group-id | Multichassis link aggregation is allowed. Also perform this step on the intermediate device. |
