Configuring Link Aggregation

Link aggregation aggregates multiple physical Ethernet ports into one logical link, also called an aggregation group. It allows you to increase bandwidth by distributing traffic across the member ports in the aggregation group. In addition, it provides reliable connectivity because these member ports can dynamically back up each other.

Networking and Configuration Requirements

Switch A aggregates ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to form one link connected to Switch B and performs load sharing among these ports.

Configuration Procedure

 

This configuration example only provides the configuration procedure on Switch A. You must perform the same configuration on Switch B for link aggregation to work.

 

Configure an aggregation group to implement load balancing on the ports in either manual aggregation mode or static LACP aggregation mode:

1)        Manual aggregation mode

# Create manual link aggregation group 1.

<SwitchA> system-view

[SwitchA] link-aggregation group 1 mode manual

# Add ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to link aggregation group 1.

[SwitchA] interface GigabitEthernet 1/0/1

[SwitchA-GigabitEthernet1/0/1] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/1] interface GigabitEthernet 1/0/2

[SwitchA-GigabitEthernet1/0/2] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/2] interface GigabitEthernet 1/0/3

[SwitchA-GigabitEthernet1/0/3] port link-aggregation group 1

2)        Static LACP aggregation mode

# Create static link aggregation group 1.

<SwitchA> system-view

[SwitchA] link-aggregation group 1 mode static

# Add ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to link aggregation group 1.

[SwitchA] interface GigabitEthernet 1/0/1

[SwitchA-GigabitEthernet1/0/1] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/1] interface GigabitEthernet 1/0/2

[SwitchA-GigabitEthernet1/0/2] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/2] interface GigabitEthernet 1/0/3

[SwitchA-GigabitEthernet1/0/3] port link-aggregation group 1

Link aggregation support of release 6300 of the S7500E series Ethernet switches differs slightly. The aggregation group configuration procedure is as follows:

l              Static aggregation mode

# Create Layer-2 aggregate interface Bridge-Aggregation 1.

<SwitchA> system-view

[SwitchA] interface bridge-aggregation 1

[SwitchA-Bridge-Aggregation1] quit

# Assign Ethernet ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to aggregation group 1.

[SwitchA] interface GigabitEthernet 1/0/1

[SwitchA-GigabitEthernet1/0/1] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/1] interface GigabitEthernet 1/0/2

[SwitchA-GigabitEthernet1/0/2] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/2] interface GigabitEthernet 1/0/3

[SwitchA-GigabitEthernet1/0/3] port link-aggregation group 1

l              Dynamic aggregation mode

# Create a Layer-2 aggregate interface Bridge-Aggregation 1, and configure the interface to operate in dynamic aggregation mode.

<SwitchA> system-view

[SwitchA] interface bridge-aggregation 1

[SwitchA-Bridge-Aggregation1] link-aggregation mode dynamic

[SwitchA-Bridge-Aggregation1] quit

# Assign Ethernet ports GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to aggregation group 1.

[SwitchA] interface GigabitEthernet 1/0/1

[SwitchA-GigabitEthernet1/0/1] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/1] interface GigabitEthernet 1/0/2

[SwitchA-GigabitEthernet1/0/2] port link-aggregation group 1

[SwitchA-GigabitEthernet1/0/2] interface GigabitEthernet 1/0/3

[SwitchA-GigabitEthernet1/0/3] port link-aggregation group 1

Complete Configuration

1)        Manual aggregation mode:

#

 link-aggregation group 1 mode manual

#

interface GigabitEthernet1/0/1

 port link-aggregation group 1

#

interface GigabitEthernet1/0/2

 port link-aggregation group 1

#

interface GigabitEthernet1/0/3

 port link-aggregation group 1

#

2)        Static LACP aggregation mode:

#

 link-aggregation group 1 mode static

interface GigabitEthernet1/0/1

 port link-aggregation group 1

#

interface GigabitEthernet1/0/2

Link aggregation support of release 6300 of the S7500E series Ethernet switches differs slightly. The aggregation group configuration procedure is as follows:

l              Static aggregation mode

#

interface Bridge-Aggregation1

#

interface GigabitEthernet1/0/1

 port link-aggregation group 1

#

interface GigabitEthernet1/0/2

 port link-aggregation group 1

#

interface GigabitEthernet1/0/3

 port link-aggregation group 1

#

l              Dynamic aggregation mode

#

interface Bridge-Aggregation1

 link-aggregation mode dynamic

#

interface GigabitEthernet1/0/1

 port link-aggregation group 1

#

interface GigabitEthernet1/0/2

 port link-aggregation group 1

#

interface GigabitEthernet1/0/3

 port link-aggregation group 1

#

Configuration Guidelines

l          Compatibility problems may occur when devices are connected to one another through static aggregation in different software, since the implementation approach of static aggregation varies with software. You can use the display version command to view the software version information.

l          An RRPP-configured port, a static MAC address or blackhole MAC address-configured port, a voice VLAN-enabled port, and an 802.1x-enabled port cannot be added to an aggregation group.
