Editing an SD-WAN interface of the LAN type

You can edit an SD-WAN interface of the LAN type in a CPE template or on a device. When you edit an SD-WAN interface of the LAN type in a CPE template, the interface is automatically modified on all devices that are using the template. When editing an SD-WAN interface of the LAN type, you can only configure the maximum speed and traffic queues.

To edit an SD-WAN interface of the LAN type:

1. Edit an SD-WAN interface of the LAN type in one of the following ways:
   • If you want to edit an SD-WAN interface of the LAN type in a CPE template, go to the SD-WAN → CPE templates menu section, click the template and in the displayed settings area, select the SD-WAN settings → Interfaces tab.
   • If you want to edit an SD-WAN interface of the LAN type on a CPE device, go to the SD-WAN → CPE menu section, click the device and in the displayed settings area, select the SD-WAN settings → Interfaces tab. If you want to edit an SD-WAN interface of the LAN type inherited from the CPE template, select the Override check box next to that interface.

   A table of SD-WAN interfaces is displayed.

2. Click Edit button next to the SD-WAN interface of the LAN type that you want to edit.
3. This opens a window; in that window, in the Maximum rate field, enter the maximum speed of the SD-WAN interface in Mbps. Range of values: 1 to 100,000. The default setting is 1000.
4. If you want to configure traffic queues on the SD-WAN interface of the LAN type:
   1. Select the QoS tab.

      A table of traffic queues is displayed.

   2. In the Minimum rate (%) column, specify the minimum traffic bandwidth for the queue as a percentage of the maximum speed of the SD-WAN interface of the LAN type. The sum total in a column may not exceed 100.
   3. In the Maximum rate (%) column, specify the maximum traffic bandwidth for the queue as a percentage of the maximum speed of the SD-WAN interface of the LAN type. This setting is used to prevent traffic of high-priority queues from indefinitely preempting traffic of low-priority queues.

   The maximum speed of the SD-WAN interface of the LAN type is specified at step 3 of these instructions.

5. Click Save.

   The SD-WAN interface of the LAN type is modified and displayed in the table.

6. In the upper part of the settings area, click Save to save the settings of the CPE template or device.
