However, before making trunk connections between switches, pay attention to：

1.The ports at both ends of a Port Aggregation connection must be configured as Aggregation Ports.

2.The ports at both ends of a Port Aggregation connection must have the same port properties, including Speed, Duplex mode.

3.All the ports of a Port Aggregation must be treated as an integer when added to/deleted from a VLAN.

4.Before connecting cables between switches, enable the Pot Aggregation to avoid looping.

5.Before disabling Port Aggregation, remove the connecting cables between switches to avoid looping.

6.Both two slide-in slots should use the identical modules (two coppers / two fibers) otherwise the Port Aggregation connection is invalid.
