Creating queues

Go to Security policy > Quality of service > Queues tab.

Creating the default queue for the WAN2 interface

  1. Click on Add.
  2. Select Class Based Queuing (CBQ).
  3. Name the queue (DEF_WAN2_Q in this example).
  4. In the Guaranteed bandwidth line, indicate the desired value for bandwidth reservation (10 Mbit/s in this example).
  5. In the Max bandwidth line, leave the value suggested by default (10 Gbit/s).
  6. In the Guaranteed rev. line, indicate the desired value for bandwidth reservation (10 Mbit/s in this example).
  7. In the Max rev. line, leave the value suggested by default (10 Gbit/s).
  8. Confirm by clicking on Apply.

NOTE
In configurations that use IPsec traffic, such traffic will automatically join the default queue for the WAN2 interface. This is why class-based queuing is applied to this queue.
Please note that the application of QoS to IPsec traffic is not covered in this Technical Note.

Creating the acknowledgment (ACK) queue for the WAN2 interface

In this example, the link connected to the WAN2 interface displays maximum bandwidth of 100 Mbit/s: the acknowledgment (ACK) queue will therefore be 5 Mbit/s (reservation equivalent to 5% of the link's maximum bandwidth).

  1. Follow the steps explained in the procedure Creating the default queue for the WAN2 interface with the following values:
Queue type Class Based Queuing
Name DEF_WAN2_ACK_Q
Guaranteed bandwidth 5 Mbit/s
Max bandwidth unlimited
Guaranteed rev. 5 Mbit/s
Max rev. unlimited

The grid of the QoS queues set in this example will therefore look like this:
