Quality of Service Features
Voice VLAN
The Voice VLAN feature enables switch ports to carry voice traffic with defined priority. The priority
level enables the separation of voice and data traffic coming onto the port. A primary benefit of using
Voice VLAN is to ensure that the sound quality of an IP phone is safeguarded from deteriorating when
the data traffic on the port is high. The system uses the source MAC address of the traffic traveling
through the port to identify the IP phone data flow.
Auto VoIP
Provides ease of use for the user in setting up VoIP for IP phones on a switch. This is accomplished by
enabling a VoIP profile that a user can select on a per port basis.
Class of Service Rate Limiting
The Class of Service interface configuration feature has been enhanced to allow outbound rate limiting
on specified ports.
Differentiated Services IPv6 Support
Extends the existing QoS ACL and DiffServ functionality by providing support for IPv6 packet
classification. Ethernet IPv6 packets are distinguished from IPv4 packets by a unique Ethertype value (all
IPv6 classifiers include the Ethertype field).
Quality of Service (QoS) Support
To overcome unpredictable network traffic and optimize performance, you can apply Quality of Service
(QoS) throughout the network. QoS ensures that the network traffic is prioritized according to a specific
criteria. Your switch supports two types of QoS: Differentiated Services and Class of Service.
• The QoS Differentiated Services (DiffServ) feature allows traffic to be classified into streams and
given certain QoS treatment in accordance with defined per-hop behaviors.
• The Class Of Service (CoS) queueing feature lets you directly configure certain aspects of switch
queuing. This provides the desired QoS behavior for different types of network traffic when the
complexities of DiffServ are not required.
