Create a Port Channel

Port channels, also called Link Aggregation Groups (LAG), are used for load balancing traffic among ports.

About this task

After you create a port channel, it is available for selection when you create ingress groups and egress.

Note

• The fields that are available for creating a port channel vary by the device you are configuring.
• LACP LAG is not supported for Extreme 9920 devices. Only static LAG is supported. The LACP LAG field is grayed out and unselected. The Static LAG field is grayed out and selected.

1. In the Navigation menu, select Configure.
2. In the Devices panel, select the device for which you want to create a port channel.
3. In the Device Config menu, select Add Port Channel.
4. In the Port Channel ID field, enter a unique numeric ID.
   No two port channels can have the same ID.
5. In the Lag Speed field, select the speed for the ports that you will select in step 7.
6. In the Description field, provide enough information to help you identify the port channel.
7. In the Ports field, select at least one port from the list.
   The ports in the list will be of the speed that you selected in step 5. A port can be a member of only one port channel. Ports that are not in the list are either already added to another port channel or are operating at a speed that is different from the selection in step 5.
8. In the MTU field, select the maximum transmission unit for packets that pass through the ports in the channel.
9. In the Minimum Link field, select or enter the minimum number of interfaces that the port channel requires to be active.
10. In the Load Balance Algorithm field, select a load-balancing method or select None.
    • src-dst-ip-l4-port: The source and destination IP Layer 4 ports method is the default load-balancing method.
    • src-dst-ip-l4-port-tid: The source and destination IP Layer 4 ports method with tunnel ID.
11. Select Enable to change the port channel operating status to Up.
    When you select this field, you initiate the no shutdown command on the device, which changes the operating status to Up. When the field is not selected, the shutdown command runs on the port channel and the operating status changes to Down.
12. Save (✔) your selections.
