DHCP Dynamic Host Conguration Protocol is used by network devices
(clients) to obtain the parameters necessary for operation in the IP
network. This protocol reduces system administration workload,
allowing devices to be added to the network with little or no manual
conguration.
DHCP should be set to On if no other information is given. When set
to On, all information on this page will be set automatically.
IP address IP address of the device (Avaya B179). The address is provided by the
network administrator or service provider if DHCP is not in use.
Hostname Set to avaya as default. Can be changed to suitable name.
Netmask Usually set to 255.255.255.0 to limit network trac to the subnet.
Domain The domain where the device is located. May be left blank.

Quality of Service
Quality of service is used in IP networks to provide dierent priority to dierent applicaions,or
to guarantee a certain level of performance to a critical data ow such as voice or video.
Dierentiated Services or DiServ is a networking architecture that species a simple mecha-
nism for classifying network tra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 dierentiate trac.
SIP DiServ Enter a value between 0 and 63 to prioritize the SIP messages.
Media DiServ 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 DiServ setting.
VLAN prio SIP Set a value between 0 and 7 to prioritize the SIP messages in the
VLAN.
VLAN prio media Set a value between 0 and 7 to prioritize the media packets in the
VLAN.
