Configuring Link Aggregation
Link aggregation aggregates multiple ports into one logical link, also called an aggregation group.
Link aggregation allows you to increase bandwidth by distributing incoming/outgoing traffic on the member ports in the aggregation group. In addition, it provides reliable connectivity because these member ports can dynamically back up each other.
Network Diagram
Figure 1-1 Network diagram for link aggregation configuration
Networking and Configuration Requirements
Aggregate Ethernet 1/0/1 through 1/0/3 on Switch A into an aggregation group and connect the group to Switch B to balance incoming/outgoing traffic among the member ports.
The example will show you how to configure link aggregation in different aggregation modes.

Configuration Procedure
The example only provides the configuration on Switch A. Perform the same configuration on Switch B to implement link aggregation.
1) In manual aggregation mode
# Create manual aggregation group 1.
<SwitchA> system-view
[SwitchA] link-aggregation group 1 mode manual
# Add Ethernet 1/0/1 through Ethernet 1/0/3 to aggregation group 1.
[SwitchA] interface Ethernet1/0/1
[SwitchA -Ethernet1/0/1] port link-aggregation group 1
[SwitchA -Ethernet1/0/1] quit
[SwitchA] interface Ethernet1/0/2
[SwitchA -Ethernet1/0/2] port link-aggregation group 1
[SwitchA -Ethernet1/0/2] quit
[SwitchA] interface Ethernet1/0/3
[SwitchA-Ethernet1/0/3] port link-aggregation group 1
2) In static LACP aggregation mode
# Create static aggregation group 1.
<SwitchA> system-view
[SwitchA] link-aggregation group 1 mode static
# Add Ethernet 1/0/1 through Ethernet 1/0/3 to aggregation group 1.
[SwitchA] interface Ethernet1/0/1
[SwitchA-Ethernet1/0/1] port link-aggregation group 1
[SwitchA-Ethernet1/0/1] quit
[SwitchA] interface Ethernet1/0/2
[SwitchA-Ethernet1/0/2] port link-aggregation group 1
[SwitchA-Ethernet1/0/2] quit
[SwitchA] interface Ethernet1/0/3
[SwitchA-Ethernet1/0/3] port link-aggregation group 1
3) In dynamic LACP aggregation mode
# Enable LACP on Ethernet 1/0/1 through Ethernet 1/0/3.
<SwitchA> system-view
[SwitchA] interface Ethernet1/0/1
[SwitchA-Ethernet1/0/1] lacp enable
[SwitchA-Ethernet1/0/1] quit
[SwitchA] interface Ethernet1/0/2
[SwitchA-Ethernet1/0/2] lacp enable
[SwitchA-Ethernet1/0/2] quit
[SwitchA] interface Ethernet1/0/3
[SwitchA-Ethernet1/0/3] lacp enable

Precautions
l If static LACP aggregation or manual aggregation is adopted, you are recommended not to cross-connect the aggregation member ports at the two ends to avoid packet loss. For example, if local port 1 is connected to remote port 2, do not connect local port 2 to remote port 1.
l Dynamic LACP aggregation mode is not recommended in actual networking scenarios.
l The implementation of static aggregation varies by platform software version. This may result in problems when products using different platform software versions are interconnected through static aggregation groups. Use the display version command to view the platform software version.
l the S3100-SI series only supports manually-configured aggregation groups.
