Huawei quidway s7700 - Adding an Eth-Trunk to an E-Trunk; Optional) Configuring the Working Mode of an Eth-Trunk in an E-Trunk

2.6.6 Adding an Eth-Trunk to an E-Trunk
After configuring an E-Trunk, you must add Eth-Trunks to the E-Trunk to implement link
aggregation between the two devices. In this manner, backup of aggregation groups is
implemented between devices and the network reliability is enhanced.
Context
Do as follows on the member devices of the E-Trunk.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
Only static LACP Eth-Trunks can be added to an E-Trunk.
Step 3 Run:
e-trunk e-trunk-id
The Eth-Trunk is added to an E-Trunk.
An Eth-Trunk can be added to only one E-Trunk.
On the two devices in an E-Trunk, the IDs of the Eth-Trunks added to the E-Trunk must be the
same. For example, if you add Eth-Trunk 1 and Eth-Trunk 2 to E-Trunk 1 on device A, you must
also add Eth-Trunk 1 and Eth-Trunk 2 to E-Trunk 1 on device B.
