Configure Quality of Service options
Quality of Service (QoS) options allow you to manage the traffic performance of various services, such
as Voice over IP (VoIP), cloud computing, traffic shaping, traffic prioritizing, and bandwidth allocation.
When configuring QOS, you can only control the queue for outgoing packets on each interface (egress
packets), not what is received on the interface (packet ingress).
A QoS
binding
contains the policies and rules that apply to packets exiting the IX20 device on the
binding's interface. By default, the IX20 device has two preconfigured QoS bindings,
Outbound
and
Inbound
. These bindings are an example configuration designed for a typical VoIP site:
n
Outbound
provides an example of matching packets as they are routed from the device onto
the WAN interface.
n
Inbound
provides an example of matching packets as they are routed from the device onto a
LAN interface.
These example bindings are disabled by default.
