MAC Address Clone (SPA122 Only)

A MAC address is a 12-digit code assigned to a unique piece of hardware for
identification purposes. Some ISPs require that you register a MAC address in
order to access the Internet. If you previously registered your account with
another MAC address, it may be convenient to assign that MAC address to your
ATA.
Use the Network Setup > Advanced Settings > MAC Address Clone page to
assign a MAC address that you previously registered with your Service Provider.
To open this page: Click Network Setup in the menu bar, and then click
Advanced Settings > MAC Address Clone in the navigation tree. After making
changes, click Submit to save your settings, or click Cancel to abandon any
unsaved entries.
Description
Flow control is a mechanism that temporarily stops the
transmission of data on a port. For example, a situation
might arise where a sending station (computer) is
transmitting data faster than some other part of the
network (including the receiving station) can accept.
The overwhelmed network element will halt the
transmission of the sender for a specified period of time.
Choose Enabled to enable this feature, or choose
Disabled to disable this feature. The default setting is
Enabled.
Choose the duplex mode. You can select from Auto-
negotiate, 10 Half, 10 Full, 100 Half and 100 Full. The
default setting is Auto-negotiate, which is
recommended to choose the appropriate mode for the
traffic. Use caution with other settings. Problems can
result if you choose a setting that is not appropriate for
the network devices.
