Dell C9000 Series Networking Configuration Manual page 825

• You may connect a PE to a parent C9010 using both uplink ports but provision the PE with only the
cascade port attached to one of the uplink ports. In this case, the auto-LAG is created with only the
provisioned cascade port when the PE comes online. In the following example, PE 10 is provisioned to
connect only to cascade port 1/12. However, the second uplink port on the PE is also cabled to cascade
port 1/0. As a result, port 1/0 is not included in the auto-LAG although it is discovered as an LLDP
neighbor.
