How to configure Static LAG Port Channel


Command

Purpose

console# configure

Enter configuration mode.

console(config)# interface range gi1/0/1-4

Enter interface-range configuration mode by entering the range of interfaces to be configured. Range command is optional.

console(config-if)# channel-group 1 mode on

Assign Group and mode static. This creates port-channel 1 as static LAG. The number is only relevant to this specific switch. Although it best practice to match the number on the corresponding switch for ease of management.

console(config-if)# end

Exit configure mode.

console# copy running-config startup-config

(Optional) Save your entries in the configuration file.




How to verify the Port Channel Status

console# show interfaces port-channel 1



How to configure a (Dynamic) LAG Port Channel using LACP


Command

Purpose

console# configure

Enter configuration mode.

console(config)# interface range gi1/0/1-4

Enter interface-range configuration mode by entering the range of interfaces to be configured. Range command is optional.

console(config-if)# channel-group 1 mode active

Assign Group and mode active.
This creates port-channel 1 as dynamic LAG.
The number is only relevant to this specific switch. Although it best practice to match the number on the corresponding switch for ease of management.

console(config-if)# end

Exit configure mode.

console# copy running-config startup-config

(Optional) Save your entries in the configuration file.

How to configure LAG Port Channel from the Web GUI



To display the LAG Membership page, click Switching / Link Aggregation / LAG Membership in the navigation panel.



Adding a Port to a Static LAG

To add a static LAG member:

1 Open the LAG Membership page.

2 Click in the LAG row under the specific port number column to toggle the port to the desired LAG number or type the desired number in the box.

The LAG number displays for that port. The LAG number increases each
time you click until the number reaches the maximum LAG number and
then returns to blank (no LAG assigned).

3 Click Apply

The port is assigned to the selected LAG, and the device is updated.

Adding a LAG Port to a Dynamic LAG by Using LACP

To add a dynamic LAG member:

1 Open the LAG Membership page.

2 Click in the LACP row under the specific port number column to toggle the desired LAG port to " L ".

The port must be assigned to a LAG before it can be aggregated to an LACP.

3 Click Apply.

The LAG port is added as a dynamic LAG member to the selected LAG.

Clicking "Apply" saves to running-config only. To save to startup-config click diskette icon at the top right of the page or System/File Management/Copy Files. Toggle "Copy Configuration" source = running config destination = startup config. Click "Apply".

Configuration options provided are validated using firmware version 5.1.6.3. Depending on the firmware version installed you may see slight differences in the command options.
