Introduction
This document provides Ethernet link aggregation configuration examples.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all the
devices were started with the factory default configuration. When you are working on a live network,
make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of Ethernet link aggregation.
Example: Configuring Layer 2 link aggregation
Network requirements
As shown in Figure 1, both Device A and Device B forward traffic from VLAN 10 and VLAN 20.
Configure link aggregation on Device A and Device B to meet the following requirements:
•VLAN 10 on Device A can communicate with VLAN 10 on Device B.
•VLAN 20 on Device A can communicate with VLAN 20 on Device B.
Figure 1 Network diagram
Requirements analysis
To enable traffic from VLAN 10 and VLAN 20 to pass through Layer 2 aggregate interface
Bridge-aggregation 1, perform the following tasks:
•Configure Layer 2 aggregate interface Bridge-aggregation 1 as a trunk port.
•Assign the aggregate interface to VLAN 10 and VLAN 20.

2
Software version used
This configuration example was created and verified on S7500EX-CMW710-R7168.
Configuration restrictions and guidelines
When you configure Layer 2 link aggregation, follow these restrictions and guidelines:
•When you assign a port to an aggregation group, the recommended configuration procedure is as
follows:
a. Use the display this command in interface view to check the following attribute configurations
of the port:
−Port isolation.
−QinQ.
−VLAN.
−VLAN mapping.
b. If any of the above configurations exist, use the undo forms of the corresponding commands to
remove these configurations. This enables the port to use the default attribute configurations.
c. Assign the port to the aggregation group.
•An aggregation group can operate in static or dynamic mode. You can choose one mode as
required.
{In a static aggregation group, the aggregation states of the member ports are not affected by
the peer ports. Static link aggregation is stable.
{In a dynamic aggregation group, the local system and the peer system automatically maintain
the aggregation states of the member ports. Dynamic link aggregation reduces the
administrators' workload.
•In a static aggregation group, the Selected state of a port is not affected by whether the peer port
is added to an aggregation group and is Selected. As a result, the Selected state of a port might be
different from the Selected state of the peer port. When both ends support static aggregation and
dynamic aggregation, H3C recommends using dynamic aggregation.
•You cannot assign a port to a Layer 2 aggregation group when MAC authentication, port security
mode, or 802.1X is configured or enabled on the port.
Configuration procedures

# Create VLAN 10, and assign port Ten-GigabitEthernet 1/0/4 to VLAN 10.

Example: Configuring Layer 2 link aggregation
in an IRF fabric
Network requirements
On the network as shown in Figure 2, perform the following tasks:
•Set up a two-chassis IRF fabric at the access layer and a two-chassis IRF fabric at the distribution
layer of the enterprise network.
•Configure link aggregation to improve the reliability of the links between the access-layer and
distribution-layer IRF fabrics and implement load sharing.
•Run LACP MAD on the two IRF fabrics to detect IRF split.
Figure 2 Network diagram
Software version used
This configuration example was created and verified on S7500EX-CMW710-R7168.
Configuration restrictions and guidelines
When you configure Layer 2 link aggregation in an IRF fabric, follow these restrictions and guidelines:

7
•IRF physical ports must be set to the bridge mode.
•When you bind physical ports to an IRF port, you must set all the physical ports to operate in either
normal or enhanced mode.
•The physical ports of two connected IRF ports must operate in the same mode: normal or enhanced.
For more information about the binding mode of the IRF physical ports, see Virtual technologies
Configuration Guide.
•When you assign a port to an aggregation group, the recommended configuration procedure is as
follows:
a. Use the display this command in interface view to check the following attribute configurations
of the port:
−Port isolation.
−QinQ.
−VLAN.
−VLAN mapping.
b. If any of the above configurations exist, use the undo forms of the corresponding commands to
remove these configurations. This enables the port to use the default attribute configurations.
c. Assign the port to the aggregation group.
•In a static aggregation group, the Selected state of a port is not affected by whether the peer port
is added to an aggregation group and is Selected. As a result, the Selected state of a port might be
different from the Selected state of the peer port. When both ends support static aggregation and
dynamic aggregation, H3C recommends using dynamic aggregation.
•You cannot assign a port to a Layer 2 aggregation group when MAC authentication, port security
mode, or 802.1X is configured or enabled on the port.
Configuration procedures
1. Configure IRF on Device A:
# Shut down ports Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/4.
# Assign member ID 1 to Device A.
[DeviceA] irf member 1
# Bind Ten-GigabitEthernet 1/0/1 to IRF port 1.
[DeviceA] irf-port 1
[DeviceA-irf-port1] port group interface ten-gigabitethernet 1/0/1
[DeviceA-irf-port1] quit
# Save the configuration
[DeviceA] quit
<DeviceA> save
# Enable IRF mode.
<DeviceA> system-view
[DeviceA] chassis convert mode irf
The device will switch to IRF mode and reboot.
You are recommended to save the current running configuration and specify the
configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file
flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Please wait...
Saving the converted configuration file to the main board succeeded.
Slot 1:
Saving the converted configuration file succeeded.
Now rebooting, please wait...
After the reboot, Device A forms a one-chassis IRF fabric. The interface number of
Ten-GigabitEthernet 1/0/1 changes to Ten-GigabitEthernet 1/1/0/1.
2. Configure IRF on Device B:
# Assign member ID 2 to Device B.
<DeviceB> system-view
[DeviceB] irf member 2
# Bind Ten-Gigabitethernet 1/0/1 to IRF port 2.
[Sysname] irf-port 2

[DeviceB-irf-port2] quit
# Save the configuration.
[DeviceB] quit
<DeviceB> save
# Connect the Device A and Device B as shown in Figure 2.
# Enable IRF mode.
<DeviceB> system-view
[DeviceB] chassis convert mode irf
The device will switch to IRF mode and reboot.
You are recommended to save the current running configuration and specify the
configuration file for the next startup. Continue? [Y/N]:y
Do you want to convert the content of the next startup configuration file
flash:/startup.cfg to make it available in IRF mode? [Y/N]:y
Please wait...
Saving the converted configuration file to the main board succeeded.
Slot 1:
Saving the converted configuration file succeeded.
Now rebooting, please wait...
After the reboot, Device B forms a two-chassis IRF fabric with Device A. The interface number of
Ten-GigabitEthernet 1/0/1 changes to Ten-GigabitEthernet 2/1/0/1.
3. Configure a Layer 2 aggregation group on Device A:
# Create Layer 2 aggregate interface Bridge-Aggregation 1, and configure the link aggregation
mode as dynamic.

[DeviceA-Bridge-Aggregation1] quit
# Assign ports Ten-GigabitEthernet 1/1/0/9, Ten-GigabitEthernet 1/1/0/10,
Ten-GigabitEthernet 2/1/0/9, and Ten-GigabitEthernet 2/1/0/10 to link aggregation group 1.

# Set the domain ID of the IRF fabric to 1.
[DeviceA] irf domain 1
# Enable LACP MAD on Bridge-Aggregation 1.
[DeviceA] interface Bridge-Aggregation 1
[DeviceA-Bridge-Aggregation1] mad enable

The assigned domain ID is: 1
MAD LACP only enable on dynamic aggregation interface.
5. Configure IRF on Device C in the same way IRF is configured on Device A. (Details not shown.)
6. Configure IRF on Device D in the same way IRF is configured on Device B. (Details not shown.)
Device C and Device D perform master election, and the one that has lost the election reboots to
form an IRF fabric with the master. In this example, Device C reboots.
7. Configure a Layer 2 dynamic aggregation group Bridge-Aggregation 1 on Device C in the same
way Bridge-Aggregation 1 is configured on Device A. (Details not shown.)
8. Configure LACP MAD on the IRF fabric:
# Set the domain ID of the IRF fabric to 2.
<DeviceC> system-view
[DeviceC] irf domain 2
# Enable LACP MAD on Bridge-Aggregation 1.
[DeviceC] interface Bridge-Aggregation 1
[DeviceC-Bridge-Aggregation1] mad enable
You need to assign a domain ID (range: 0-4294967295)
