Configuring LAG LAG Configuration
Configuration Guide

Port Priority
(0-65535)
Specify the Port Priority. A smaller value means a higher port priority.
The port with higher priority in an LAG will be selected as the active port to
forward data. If two ports have the same priority value, the port with a smaller
port number has the higher priority.
Mode Select the LACP mode for the port.
In LACP, the switch uses LACPDU (Link Aggregation Control Protocol Data Unit)
to negotiate the parameters with the peer end. In this way, the two ends select
active ports and form the aggregation link. The LACP mode determines whether
the port will take the initiative to send the LACPDU. There are two modes:
Passive: The port will not send LACPDU before receiving the LACPDU from the
peer end.
Active: The port will take the initiative to send LACPDU.
Note:
For successful LACP negotiation, make sure at least one end of the link is
configured as Active.
Status Enable the LACP function of the port. By default, it is disabled.

2.2.1 Configuring Load-balancing Algorithm
Follow these steps to configure the load-balancing algorithm:
Step 1 configure
Enter global configuration mode.
Step 2 port-channel load-balance { src-mac | dst-mac | src-dst-mac | src-ip | dst-ip | src-dst-ip }
Select the Hash Algorithm. The switch will choose the ports to transfer the packets based
on the Hash Algorithm. In this way, different data flows are forwarded on different physical
links to implement load balancing.
src-mac: The computation is based on the source MAC addresses of the packets.
dst-mac: The computation is based on the destination MAC addresses of the packets.
src-dst-mac: The computation is based on the source and destination MAC addresses of
the packets.
src-ip: The computation is based on the source IP addresses of the packets.
dst-ip: The computation is based on the destination IP addresses of the packets.
src-dst-ip: The computation is based on the source and destination IP addresses of the
packets.
