Network Config - Avaya 3641 Administration Manual

Network Config

IP Addresses
There are two modes in which the handset can operate: DHCP-enabled or Static IP.
Select the mode for operation from the IP Address menu:
Use DHCP mode will use Dynamic Host Configuration Protocol to assign an IP Address
each time the handset is turned on. If DHCP is enabled, the handset also receives all
other IP Address configurations from the DHCP server. If a needed parameter is not
supplied by DHCP and there is a static value, the static value will be used.
You can use the Static IP to manually set a fixed IP Address. If you have selected Static
IP, the handset will prompt for the IP addresses for each configurable network
component. When entering addresses, enter the digits only, including leading zeroes.
Regardless of the mode in which the handset is operating, the following components are
required and must be configured as part of the SIP system:
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 are used to identify subnets, when using a
complex network, which includes routers. Both of these must be configured either
with an IP address under Static IP. These must not set 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 the network administrator for the
proper settings for the network.
Note:
You cannot use Avaya 3641/3645/6120/6140 IP Wireless Handsets with uninterrupted
service between subnets unless specific LAN components are present. Certain
AP/Ethernet switch combinations establish a Layer-2 tunnel across subnets that enable
the handsets to roam. Without this capability, any call in progress is dropped when the
user moves out of range and the handset must restart in order to to resume functionality
in the new subnet area.
Ensure that all your APs are attached to the same subnet for proper operation. The
handset can change subnets if DHCP is enabled and the handset is powered off and
then powered on when within range of APs on the new subnet. Note that you cannot "
roam" with wireless handsets across subnets, since the handsets cannot change IP
addresses while they are operational.
Note:
See Best Practices for Deploying Enterprise-Grade Wi-Fi Telephony for detailed
configuration information.
File Servers:The file server holds software images for updating the handsets and
contains the handset files. If the HTTP server IP or TFTP server IP is configured (not set
