H3C Switch Link Aggregation Configuration Method

configuration steps

Configuration of switch A

Use dynamic aggregation mode: create a Layer 2 aggregation interface and configure dynamic aggregation mode

[Device A]interface bridge-aggregation 1
[Device A-Bridge-Aggregation1] link-aggregation mode dynamic
[Device A-Bridge-Aggregation1] quit
[Device A]interface gigabitethernet 1/0/1
[Device A-GigabitEthernet1/0/ 1] port link-aggregation group 1
[Device A-GigabitEthernet1/0/1] quit
[Device A]interface gigabitethernet 1/0/2
[Device A-GigabitEthernet1/0/2] port link-aggregation group 1
[Device A- GigabitEthernet1/0/2] quit
[Device A]interface gigabitethernet 1/0/3
[Device A-GigabitEthernet1/0/3] port link-aggregation group 1
[Device A-GigabitEthernet1/0/3] quit
[Device A]interface bridge-aggregation 1
[Device A-Bridge-Aggregation1] port link-type trunk
[Device A-Bridge-Aggregation1] port trunk permit vlan all
[Device A-Bridge-Aggregation1] quit
[Device A] save force

Configuration of switch B

[Device B]interface bridge-aggregation 1
[Device B-Bridge-Aggregation1] link-aggregation mode dynamic
[Device B-Bridge-Aggregation1] quit
[Device B]interface gigabitethernet 1/0/1
[Device B-GigabitEthernet1/0/ 1] port link-aggregation group 1
[Device B-GigabitEthernet1/0/1] quit
[Device B]interface gigabitethernet 1/0/2
[Device B-GigabitEthernet1/0/2] port link-aggregation group 1
[Device B- GigabitEthernet1/0/2] quit
[Device B]interface gigabitethernet 1/0/3
[Device B-GigabitEthernet1/0/3] port link-aggregation group 1
[Device B-GigabitEthernet1/0/3] quit
[Device B]interface bridge-aggregation 1
[device B-Bridge-Aggregation1] port link-type trunk
[device B-Bridge-Aggregation1] port trunk permit vlan all (here configure which vlans are allowed to pass according to the network requirements you need
[Device B-Bridge-Aggregation1] quit
[Device B] save force

Check configuration effect

[H3C]display link-aggregation verbose

Result description

Check whether the member ports in the aggregation group on the local and remote devices are in the Selected state. If the status is consistent, it means that the link aggregation is successfully configured.
