Ethernet link aggregation configuration examples
NOTE:
In an aggregation group, only ports that have the same port attributes and class-two configurations
(see ”Configuration classes”) as the reference port (see “Reference port”) can operate as Selected ports.
You must ensure that all member ports have the same port attributes and class-two confi
urations as the
reference port. The other settings only need to be configured on the aggregate interface, not on the
member ports.

Network requirements
As shown in Figure 8:
• Device A and Device B are connected through their respective Layer 2 Ethernet interfaces Ethernet
1/0/1 through Ethernet 1/0/3.
