Shut down the aggregate 
interface 

Required 

By default, aggregate 
interfaces are up.  

 

You are recommended not to perform the undo shutdown and then shutdown commands on a 

member port of the aggregation group corresponding to an aggregate interface that is already shut 

down. Otherwise, when the member port is brought up, the selected state of the remote port will be 

affected.  

 

The hash algorithm is adopted to calculate load sharing for load-sharing link aggregation groups. Hash 

keys used for calculation could be service port numbers, IP addresses, MAC addresses, incoming ports, 

or any combinations of them. One hash key or a combination of multiple hash keys represents a load 

sharing mode. You can change the load sharing mode of a link aggregation group for different types of 

traffic as needed.  

You can configure a global load sharing mode for all link aggregation groups or a load sharing mode 

specific to a link aggregation group as needed. 

Follow these steps to configure the global load sharing mode for link aggregation groups: 

Enter system view 

— 

Configure the global 
link aggregation load 
sharing mode 

link-aggregation load-sharing 
mode { destination-ip | 
destination-mac | 
destination-port | ingress-port | 
source-ip | source-mac | 
source-port } * 

Optional 

By default, the hash keys for Layer 2 
packets are source/destination MAC 
addresses, and those for Layer-3 
packets are source/destination IP 
addresses.  

This command applies only to the 
load sharing mode of Layer 3 
packets. After you configure this 
command, the Layer 3 load sharing 
modes in all link aggregation groups 
change accordingly, but the Layer 2 
load sharing modes will not be 
affected. The default 
source/destination MAC addresses 
will still be used as the hash keys
