Virtual Lan Overview; Vlan Separation - Avaya 9600 Series Installing And Administering

Option 6 contains a list of DNS addresses, those addresses are queried in the order given if no
response is received from previous addresses on the list. As an alternative to administering DNS
by DHCP, you can specify the DNS server and or the domain name in the HTTP script file. But first
SET the DNSSRVR and DOMAIN values so that you can use those names later in the script.
Note:
Administer Options 6 and 15 with DNS servers and domain names respectively.

Virtual LAN overview

Virtual LANs (VLANs) are used to segregate your network into groups or domains. They can also
prioritize the network traffic into each domain. For example, a network can have a Voice VLAN
and a Data VLAN. This functionality of grouping devices that have a set of common requirements
can simplify network design, increase scalability, improve security, and improve network
management. Therefore, you must always use VLANs in your network.
The networking standard that describes VLANs is IEEE 802.1Q. This standard describes the
802.1Q protocol and the way in which an additional four-byte VLAN tag is inserted at the
beginning of an Ethernet frame. This additional VLAN tag describes the VLAN ID to which a
particular device belongs and the priority of the VLAN tagged frame. Voice and video traffic get a
higher priority in the network because they are subject to degradation caused by network jitter and
delay.

VLAN separation

A phone has an internal network switch that can use VLANs to segregate traffic going to the LAN
port, the PC port, and the internal port that goes to the CPU of the phone. You can have VLAN
functionality on this switch. Also, you can configure the switch to separate the traffic moving
towards the CPU of the phone from the traffic moving towards the PC port.
You can configure the internal switch of the phone by using the 46xxsettings.txt file, LLDP,
or DHCP. However, you must configure the VLAN settings on the internal switch of the phone only
through DHCP or LLDP because these protocols are run before and during network initialization. If
that is not possible, then use the 46xxsettings.txt file configuration parameters and start the
VLAN in automatic mode, which is the default mode.
