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 Connect IT 16/48 device
on the binding's interface. By default, the Connect IT 16/48 device has two preconfigured QoS
bindings, Outbound and Inbound. These bindings are an example configuration designed for a typical
VoIP site:
Outbound provides an example of matching packets as they are routed from the device onto
n
the WAN interface.
Inbound provides an example of matching packets as they are routed from the device onto a
n
LAN interface.
These example bindings are disabled by default.
