Parameter Description
VLANTEST Number of seconds to wait for a DHCPOFFER on a non-zero VLAN. The default is 60
seconds.
In an IP Office environment 46xxsettings.txt and 96x1Supgrade.txt files are

custom Settings file.
DHCP options
You can configure the following options in the DHCP server:
Option Description
Option 1 Specifies the subnet mask of the network.
Option 3 Specifies the gateway IP address list. The list can contain up to 127 total ASCII
characters. Separate more than one IP address with commas with no intervening
spaces.
Option 6 Specifies the DNS server address list. The list can contain up to 127 total ASCII
characters. Separate more than one IP address with commas with no intervening
spaces.
The phone supports DNS and the dotted decimal addresses. The phone attempts to
resolve a non-ASCII-encoded dotted decimal IP address by checking the contents of
DHCP Option 6. At least one address in Option 6 must be a valid, nonzero, dotted
decimal address, otherwise the DNS address fails.
Option 12 Avaya J100 Series IP Phones identify themselves to the DHCP server by sending
the host name in Sub-Option 12 in DHCP DISCOVER and DHCP REQUEST options.
The host name has the following format:
AVohhhhhh, where:
• AV stands for Avaya.
• o is one of the following values based on Object Unique Identifier (OUI) derived
from the first three octets of the phone MAC address:
- A if OUI is 00-04-0D
- B if OUI is 00-1B-4F
- E if OUI is 00-09-6E
- L if OUI is 00-60-1D
- T if the OUI is 00-07-3B
- X if the OUI is anything else
• hhhhhh are the ASCII characters for the hexadecimal representation of the last
three octets of the phone MAC address.
