Gratuitous Address Resolution Protocol Protection

Gratuitous Address Resolution Protocol (GARP) Protection protects the IP
Phone 1150E from GARP Spoof attacks on the network. In a GARP Spoof
attack, a malicious device on the network takes over an IP address (usually
the default gateway) by sending unsolicited (or Gratuitous) ARP messages,
thus manipulating the ARP table of the victim machine. The malicious
device launches a variety of attacks on the network, that results in undesired
traffic routing. For example, a GARP attack can convince the victim machine
that the malicious device is the default gateway. In this scenario, all traffic
from the victim machine flows through the malicious device.
To enable GARP Protection during configuration, see
"Installing the IP Phone 1150E " (page

Extensible Authentication Protocol

Extensible Authentication Protocol (EAP) is a general protocol that fulfills
the protocol requirements defined by 802.1x. For further information about
802.1x, see
469).

Bluetooth wireless technology

The IP Phone 1150E supports Bluetooth wireless technology . For
information about configuring Bluetooth wireless technology on the IP
Phone 1150E, see

Redeploying an IP Phone 1150E

You can redeploy an existing previously configured IP Phone 1150E on
the same system. For example, the IP Phone 1150E can be assigned to
a new user (new TN) or to an existing user who moved to a new subnet
by changing the TN of the IP Phone 1150E. For further information, see
Converging the Data Network with VoIP Fundamentals (NN43001-260).
