Configuring QoS on the LAN and WAN interfaces

Go to Security policy > Quality of service > Traffic shaper tab, Interfaces with QoS grid.

This phase of the configuration involves associating the following with each QoS-enabled interface:

  • A traffic shaper,
  • A default queue: any traffic that does not have a defined QoS queue in the filter rule that applies to such traffic will join this queue.
  • A default acknowledgment queue.

Configuring QoS on the LAN interface

  1. Click on Add.
  2. Select the LAN interface.
  3. Select the Traffic shaper for this interface (TS_LAN in this example).
  4. Select the Default queue for this interface (DEF_LAN_Q in this example).
  5. Select the Default ACK queue (DEF_LAN_ACK_Q in this example).
  6. Confirm by clicking on Apply.

Configuring QoS on the WAN interface

Follow the steps explained in the previous section (Configuring QoS on the LAN interface), using the following values:

Interface WAN
Traffic shaper TS_WAN
Default queue DEF_WAN_Q
Default ACK queue DEF_WAN_ACK_Q

The grid of the interfaces on which QoS has been enabled in this example will therefore look like this:

VLANs attached to an interface

If one or several VLANs are attached to a physical interface (LAN interface in this example), the following must be assigned to each VLAN interface:

  • The traffic shaper of the parent interface (TS_LAN in this example),
  • A default queue: this is a queue specific to the VLAN (if a bandwidth guarantee is ever needed for this VLAN) or queue for the parent interface (DEF_LAN_Q in this example),
  • The default acknowledgment (ACK) queue of the parent interface (DEF_LAN_ACK_Q in this example).

Similarly to physical interfaces, ensure that the total amount of bandwidth reserved for VLANs does not exceed the value of the traffic shaper.
