Multiple physical interfaces can be bundled into an Eth-Trunk using the link aggregation technique. The Eth-Trunk interface is a logical interface, having all functions of an Ethernet interface and is more reliable.
This section describes Ethernet interface features supported by the NetEngine 8000 F. Familiarizing yourself with these features helps you complete the configuration tasks quickly and accurately.
You can configure Eth-Trunk interfaces working in manual load balancing mode on two connected devices if one or both of them do not support LACP. Then, you can add physical interfaces to the Eth-Trunk interfaces to increase bandwidth and improve reliability.
If two LACP-capable devices are directly connected through an Eth-Trunk link, you can configure the Eth-Trunk interfaces on the two devices to work in static LACP mode. Eth-Trunk interfaces working in static LACP mode implement both load balancing and link backup.
When intermediate devices exist between the devices at both ends of an Eth-Trunk link, configure Eth-Trunk interfaces in manual 1:1 master/backup mode on the devices at both ends, add two interfaces to each Eth-Trunk interface, and specify the master interface.
To allow a Huawei device to communicate with a non-Huawei device that uses master and backup interfaces (both in the Up state), configure an Eth-Trunk interface in manual 1:1 master/backup mode on the Huawei device.
