Introduction 87
Duplex
In the Network menu, Auto Negotiation mode is the default setting for
initial startup. Typically, the IP Phone 1140E is connected to a network
that supports Auto Negotiation, and the IP Phone 1140E selects the best
speed and duplex mode available. There is no intervention required under
normal operation.
ATTENTION
Nortel recommends that Auto Negotiation mode is used on the network and the
IP Phone 1140E. Use Full Duplex mode only when the entire network is running
in Full Duplex mode. Otherwise, a duplex mismatch results.
Note: Changing the speed, or the duplex mode, or both on the IP
Phone 1140E changes both the LAN Ethernet port and PC Ethernet
Port interfaces.
If the IP Phone is connected to a network configured for Full Duplex mode
only, the IP Phone 1140E cannot automatically negotiate the proper
configuration. Therefore, in this instance, to allow the IP Phone 1140E
to work at the optimum speed and duplex mode, Full Duplex mode must
be enabled.
Ignore GARP
Gratuitous Address Resolution Protocol (GARP) Protection prevents the IP
Phone 1140E with SIP Firmware from GARP spoof attacks on the network.
The IP Phone 1140E with SIP Firmware provides the ability to ignore GARP
messages.

The next four menu items apply to configuring the provisioning parameters.
Server URL Enter the numeric IP address, name, or URL of the
provisioning server in the Server URL box.

TFTP, FTP, or HTTP.
Device ID Enter the Device ID (User ID) used by the provisioning server
for authentication of the IP Phone 1140E with SIP Firmware.

authentication of the IP Phone 1140E with SIP Firmware.
