Huawei quidway s7700 - Checking the Configuration; Configuring an E-Trunk; Establishing the Configuration Task

When more than one IP address is set for an Eth-Trunk interface, the keyword sub can be used
to indicate the IP addresses other than the first IP address.

2.5.4 Checking the Configuration
Procedure
l Run the display interface eth-trunk [ trunk-id [.subnumber ] ] command to check the
status of an Eth-Trunk interface.
----End
2.6 Configuring an E-Trunk
As an extension to the Link Aggregation Protocol (LACP) that implements link aggregation on
a single device, the Enhanced Trunk (E-Trunk) protocol implements link aggregation between
different devices. This improves link reliability between devices.
2.6.1 Establishing the Configuration Task
Before configuring an E-Trunk, familiarize yourself with the applicable environment, complete
the pre-configuration tasks, and obtain the data required for the configuration. This will help
you complete the configuration task quickly and accurately.
Applicable Environment
As shown in Figure 2-4, the E-Trunk is used to protect the links between a CE and two PEs
when the CE is dual-homed to the two PEs. The CE is connected to PE1 and PE2 through a static
LACP Eth-Trunk respectively. The two Eth-Trunks form an E-Trunk to implement backup of
link aggregation groups between PE1 and PE2, enhancing the network reliability.
