Configuring the Standard Priority Queue for an Interface
If you enable standard priority queuing for traffic on a physical interface, then you need to also create
the priority queue on each interface. Each physical interface uses two queues: one for priority traffic,
and the other for all other traffic. For the other traffic, you can optionally configure policing.
Note The standard priority queue is not required for hierarchical priority queuing with traffic shaping; see the
“Information About Priority Queuing” section on page23-3 for more information.
Restrictions
•(ASASM) The ASASM does not support priority queuing.
•(ASA 5580) You cannot create a standard priority queue for a Ten Gigabit Ethernet interface. Note:
For the ASA 5585-X, standard priority queuing is supported on a Ten Gigabit Interface.
•(ASA 5512-X through ASA 5555-X) Priority queuing is not supported on the Management 0/0
interface.
Detailed Steps
2. Typically, the maximum size is 1538 bytes, or 1542 bytes for tagged Ethernet. If you allow jumbo frames (if supported for your
platform), then the packet size might be larger.
3. The delay depends on your application. For example, to control jitter for VoIP, you should use 20 ms.
Command Purpose
Step1 priority-queue interface_name
Example:
ciscoasa(config)# priority-queue inside
Creatse the priority queue, where the interface_name argument
specifies the physical interface name on which you want to enable
the priority queue, or for the ASA 5505 or ASASM, the VLAN
interface name.
