Duplex; Ignore Garp; Provisioning - Nortel 1120E Administration Manual

Duplex

In the Network menu, Auto Negotiation mode is the default setting for
initial startup. Typically, the IP Phone 1120E is connected to a network
that supports Auto Negotiation, and the IP Phone 1120E selects the best
speed and duplex mode available. There is no intervention required under
normal operation.
Nortel recommends that Auto Negotiation mode is used on the network and the
IP Phone 1120E. Use Full Duplex mode only when the entire network is running
in Full Duplex mode. Otherwise, a duplex mismatch results.
If the IP Phone is connected to a network configured for Full Duplex mode
only, the IP Phone 1120E cannot automatically negotiate the proper
configuration. Therefore, in this instance, to allow the IP Phone 1120E
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 1120E with SIP Firmware from GARP spoof attacks on the network.
The IP Phone 1120E with SIP Firmware provides the ability to ignore GARP
messages.
