Configuration in the Eth-Trunk interface view
1. Run:
system-view
The system view is displayed.
2. Run:
interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
3. Run:
trunkport interface-type { interface-number1 [ to interface-number2 ] }
&<1-8>
Member interfaces are added to the Eth-Trunk.
Configuration in the member interface view
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run:
eth-trunk trunk-id
The interface is added to the Eth-Trunk.
When adding an interface to an Eth-Trunk, pay attention to the following points:
– An Eth-Trunk contains a maximum of eight member interfaces.
– A member interface cannot be configured with any service or static MAC address.
– When adding an interface to an Eth-Trunk, ensure that the interface is a hybrid interface,
which is the default interface type.
– An Eth-Trunk cannot be nested, that is, its member interfaces cannot be Eth-Trunk.
– An Ethernet interface can be added to only one Eth-Trunk interface. To add the Ethernet
interface to another Eth-Trunk, delete the Ethernet interface from the current Eth-Trunk
first.
– The member interfaces of an Eth-Trunk must be of the same type. For example, the FE
interface and the GE interface cannot be added to the same Eth-Trunk.
– Ethernet interfaces on different LPUs can be added to the same Eth-Trunk.
– The peer interface directly connected to the Eth-Trunk on the local end must also be
added to an Eth-Trunk; otherwise, the two ends cannot communicate.
– When the rates of member interfaces are different, the interfaces with a smaller rate may
be congested, and packets may be lost.
– After an interface is added to an Eth-Trunk, MAC address learning is performed by the
Eth-Trunk rather than the member interfaces.
