Table 1 compares the manual mode and LACP mode.
Item |
Manual Mode |
LACP Mode |
|---|---|---|
Eth-Trunk setup mode |
You must manually create an Eth-Trunk and add member interfaces to the Eth-Trunk. |
An Eth-Trunk is created using LACP, which provides a standard negotiation mechanism that a switch can use to create and start the aggregated link based on its configuration. LACP maintains the link after the aggregated link is created, adjusting or removing the link if an aggregated link's status changes. |

Data forwarding |
When the aggregated link is operating normally and all links are active links participating in data forwarding, if one active link fails, traffic is load balanced among the remaining active links. |
When the aggregated link is operating normally but only some links are active links, all active links participate in data forwarding. If an active link fails, the system selects one of the inactive links to be the active link, ensuring the number of links participating in data forwarding remains unchanged. |
Inter-device link aggregation |
Not supported |
Supported |
Fault detection |
This mode can only detect member link disconnections. |
This mode can detect member link disconnections, link layer faults, and incorrect link connections. |
