Huawei router: the Eth-Trunk Technology

The Eth-Trunk interface is a dynamically created interface, Huawei Transmission the interface can Ethernetinterface binding number of physics as a logical interface. Added to the Ethernet interface and Eth-Trunk interface are called member interface. Users only need to configure Eth-Trunk interface, the configuration will eventually mapped to member interface.

Huawei NE40 series universal switching router support routing model and two kinds of Eth-Trunk interface switching mode, switching between the two modes of interface support. Eth-Trunk interface and Ethernet interface routing mode routing model is similar, you can configure the IP address, operating a variety of routing protocols, MPLS VPN and other business. Eth-Trunk interface switching mode and the Ethernet interface exchange patternsimilar, can join the VLAN, run the STP protocol. The main characteristics of the Eth-Trunkinterface with expansion interface bandwidth, increase the link reliability and flow load sharing.

Methods the following introduce configuration of Eth-Trunk in Huawei on NE40 router:

Step 1 configure NE40E

<Quidway> System-View

[Quidway] sysname NE40E

Create a Eth-Trunk interface, and the configuration of IP address.

[NE40E] interface eth-trunk 1

[NE40E-Eth-Trunk1] IP address 192.1.1.1 24

[NE40E-Eth-Trunk1] quit

Huawei router NE40E, NE80E Eth-trunk is the default routing mode, if you want to bind toVLAN, two layer model from the three layer mode switching to Eth-Trunk interface. Thecommand will change the mode to exchange mode.

[NE40E] interface eth-trunk 1

[NE40E-Eth-Trunk1]portswitch

Execute the command portswitch, will the Eth-Trunk interface from the three layer mode to the two layer model. Switch to the two layer model, the three layers of the Eth-Trunk function and the indicator is forbidden, the SRU board (main control board) on Meth0 interface MAC address. Execute the undo portswitch command can be Eth-Trunk interface back to thethree layer model from the two layer mode switching.

The port GE1/0/0, GE2/0/0 into Eth-Trunk 1.

[NE40E] interface gigabitethernet 1/0/0

[NE40E-GigabitEthernet1/0/0] eth-trunk 1

[NE40E-GigabitEthernet1/0/0] quit

[NE40E] interface gigabitethernet 2/0/0

[NE40E-GigabitEthernet2/0/0] eth-trunk 1

[NE40E-GigabitEthernet2/0/0] quit

Step 2 check the configuration results

Implementation of display interface eth-trunk command in the NE40E, you can see theinterface state is UP.

[NE40E] display interface eth-trunk 1

Eth-Trunk1 current state: UP

Line protocol current state: UP

Hash arithmetic: According to MAC

When a router when switching mode using according to the MAC address hash

Hash arithmatic: According to IP

When a router when routing model is used according to the IP address hash

[NE40E] display trunkmembership eth-trunk 1
