Reinstalling an IP Phone 2007

— Speed: 10 (Mb) or 100 (Mb)
— Auto-Negotiate Capability: N
— Auto-Negotiate Completed: N
Gratuitous Address Resolution Protocol (GARP) Protection prevents the
IP Phone 2007 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's machine. The malicious
device launches a variety of attacks on the network, resulting 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's machine flows through the malicious device.
To enable GARP Protection during configuration, refer to Procedure 25,
"Configuring the IP Phone 2007" on
Extensible Authentication Protocol (EAP) is a general protocol that fulfills
the protocol requirements defined by 802.1x. For further information on
802.1x, refer to Appendix C "802.1x Port-based network access control" on
page 493.
You can reinstall an existing, previously-configured IP Phone 2007 on the
same system. For example, the IP Phone 2007 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 2007.
