Answer:
You can add a member interface to a link aggregation group in either of the following ways:
In the Eth-Trunk interface view, run the trunkportinterface-type { interface-number1 [ to interface-number2] } &<1-16> command to add member interfaces to the Eth-Trunk interface in batches.
Alternatively, in the member interface view, run the eth-trunk trunk-id command to add the current interface to the Eth-Trunk interface.
You can delete a member interface from a link aggregation group in either of the following ways:
In the Eth-Trunk interface view, run the undo trunkportinterface-type { interface-number1 [ to interface-number2] } &<1-16> command to delete member interfaces in batches.
Alternatively, run the undo eth-trunk command in the member interface view to delete the current interface from the Eth-Trunk interface.
The following is an example:
# Add GigabitEthernet1/0/1 to GigabitEthernet1/0/5 to Eth-Trunk 1.
<HUAWEI> system-view
[HUAWEI] interface eth-trunk 1
[HUAWEI-Eth-Trunk1] trunkport gigabitethernet 1/0/1 to 1/0/5
# Add GigabitEthernet0/0/1to Eth-Trunk 2.
<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] eth-trunk 2
# Delete GigabitEthernet0/0/1 from Eth-Trunk 1.
<HUAWEI>system-view
[HUAWEI]interface eth-trunk 1
[HUAWEI-Eth-Trunk1]undo trunkport gigabitethernet 0/0/1
# Delete GigabitEthernet0/0/1 from Eth-Trunk 1.
<HUAWEI>system-view
[HUAWEI]interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1]undo eth-trunk
Thanks!
