Quality of Service
Quality of service is used in IP networks to provide different priority to different applica-
tions, users, or to guarantee a certain level of performance to a critical data ow such as
voice or video. Differentiated Services or DiffServ is a networking architecture that speci-
es a simple mechanism for classifying network trafc using a 6-bit eld in the header of
the IP packets. VLAN (Virtual LAN) is a technology to logically divide a physical network
into several logical nets and thus to differentiate trafc.
SIP DiffServ Enter a value between 0 and 63 to prioritize the SIP messages.
Media DiffServ Enter a value between 0 and 63 to prioritize the media packets
(voice).
VLAN By enabling this option, all communication to and from Avaya B179
is done via the VLAN specied under VLAN ID. Note that this
VLAN also must be used to communicate with Avaya B179 via the
web interface.
VLAN ID The ID number to be used for the IP telephony VLAN.
VLAN map enable Enabling VLAN priority mapping from the DiffServ setting.
VLAN prio SIP Set a value between 0 and 7 to prioritize the SIP messages in the
