The system view is displayed.
2. Run:
interface interface-type interface-number
The member interface view is displayed.
3. Run:
eth-trunk trunk-id
The member interface is added to an Eth-Trunk.
When adding an interface to an Eth-Trunk, pay attention to the following points:
– An Eth-Trunk contains a maximum of 8 member interfaces.
– A member interface cannot be configured with some services or static MAC addresses.
– When adding an interface to an Eth-Trunk, ensure that the interface uses the default link
type.
– An Eth-Trunk cannot be added to another Eth-Trunk.
– An Ethernet interface can be added to only one Eth-Trunk. To add the Ethernet interface
to another Eth-Trunk, delete it from the Eth-Trunk first.
– Member interfaces of an Eth-Trunk must use the same type.
– If an interface of the local device is added to an Eth-Trunk, an interface of the remote
device directly connected to the interface of the local device must also be added to an
Eth-Trunk so that the two ends can communicate.
– After interfaces are added to an Eth-Trunk, the Eth-Trunk learns MAC addresses and
ARP entries but member interfaces do not.
– Devices at both ends of an Eth-Trunk must use the same number of physical interfaces,
interface rate, duplex mode, jumbo and flow control mode.

Follow-up Procedure
You can configure Eth-Trunk member interfaces to send trap messages after the Eth-Trunk
member interface status changes. After the device receives a trap message, check whether the
device fails or recovers.
If you need to know the status change of the member interface of a specified Eth-Trunk, run the
trunk-member trap in private-mib enable command to enable Eth-Trunk member interfaces
to use the proprietary MIB to send trap messages. The trap messages sent by using the proprietary
MIB carry Eth-Trunk IDs, whereas the trap messages sent by using the public MIB do not carry
Eth-Trunk IDs.
NOTE
After the trunk-member trap in private-mib enable command is configured, Eth-Trunk member
interfaces only use the proprietary MIB to send trap messages. To view these trap messages, use the Huawei
proprietary MIB.
