- Partial DHCP—enables static IP address configuration for Server 1, Server 1 Port,
Server 2, and Server 2 Port. All other IP addresses are assigned by DHCP.
Server 1 (2) IP address—the IP addresses of the primary and secondary Avaya
device. If using Static IP configuration, this is the IP address of the device. If DHCP is
used, the handset tries to obtain the IP address and port information by using the
following DHCP options: 43, 128, 144, 157, 191, and 251.
Server 1 (2) Port—the port number used by the primary and secondary Avaya device
to communicate with IP telephones. If using Static IP configuration consult your
Avaya documentation for port numbers. If DHCP is used, the handset tries to obtain
the IP address and port information by using the following DHCP options: 43, 128,
144, 157, 191, and 251.
• Static IP—allows you to manually set a fixed IP address. If selected, the handset prompts
for the IP Addresses of each configurable network component. When entering addresses,
enter the digits only, including leading zeroes. No periods are required.
Regardless of the mode in which the handset is operating, you must configure the following
components:
• Phone IP—the IP address of the handset. This is automatically assigned if DHCP is used.
If using Static IP configuration, you must obtain a unique IP address for each handset
from your network administrator.
• Default Gateway and Subnet Mask—used to identify subnets, when using a complex
network that includes routers. Both of these must be configured either with an IP address
under Static IP (not configured to 000.000.000.000 or 255.255.255.255) or with DHCP
for the handset to contact any network components on a different subnet. If configured
on the DHCP server, use option 3 for the Default Gateway and option 1 for the Subnet
Mask. Contact your network administrator for the proper settings for your network.
Important:
An Avaya 6120/6140 WLAN Handset cannot roam across subnets because it cannot
change its IP address while it is operational. Ensure that all your access points are
attached to the same subnet for proper operation. If DHCP is enabled, you can change
the subnet of the handset by turning off the handset, and then turning it back on when it
is within range of access points on the new subnet.
• TFTP Server IP—the IP address of a TFTP server on your network that holds hardware
images for updating the handsets. If this feature is configured (not configured to 0.0.0.0
or 255.255.255.255), either by using Static IP configuration or by using DHCP option 66
(TFTP Server), or the Boot server/next server (siaddr) field, the handset checks for newer
hardware each time it is powered on or comes back into range of your network. This check
takes only a second and ensures that all handsets in your network are kept up-to-date
with the same version of hardware.
• Syslog Server IP—the IP address of the Syslog Server.
• Time Server IP—the IP address of the time server.
• SVP IP address—the IP address of the WLAN IP Telephony Manager 2245. If you use
the Static IP configuration, this is simply the IP address of the WLAN IP Telephony
