Qos (Quality Of Service); Mac Address Clone - Linksys BEFSR81 User Manual

QoS (Quality of Service)

Quality of Service (QoS) is used to maximize a network's performance accord-
ing to its requirements and can be set from the QoS screen, shown in Figure 6-
26. QoS ensures better service to high-priority types of network traffic, which
may involve demanding, real-time applications, such as videoconferencing.
QoS To use QoS, select Enable. To disable QoS, select Disable.
There are two types of QoS available: Application-based and Port-based.
Application-based QoS This feature manages information as it is transmitted
and received and assigns it a high or low priority based upon the selections
made on this screen. You can also choose to disable QoS for a specific appli-
cation. There are five preset applications that utilize Application-based QoS:
FTP, HTTP, Telnet, SMTP, and POP3. You can choose three additional applica-
tions by entering their respective port numbers in the Specific Port # fields.

Port-based QoS Port-based QoS settings allow you to prioritize performance
on four of the Router's ports (LAN ports 1-4). You can also disable QoS for a
specific port. The Router's other four ports are automatically assigned Low
Priority. Port-Based QoS does not require support from your ISP as the priori-
tized ports are LAN ports going out to your network.
When finished, click the Apply button to save the settings. Otherwise, click the
Cancel button to undo changes made on this screen.

MAC Address Clone

From the MAC Address Clone screen, shown in Figure 6-25, you can change
the Router's WAN Mac Address.
The Router's MAC address is a 12-digit code assigned to a unique piece of
hardware for identification, like a social security number. If your ISP requires
MAC address registration, find your adapter's MAC address by following the
instructions in "Appendix F: Finding the MAC Address and IP Address for
Your Ethernet Adapter."
Enter the 12 digits of your adapter's MAC address in the on-screen fields (see
Figure 6-27). This "clones" your Ethernet adapter's MAC address onto the
Router, so you do NOT have to call your ISP to change the registered MAC
address to the Router's MAC address.
When finished making your changes on this tab, click the Apply button to save
these changes, or click the Cancel button to undo your changes.
