MAC Filtering
In some cases, you may want to manage Layer2 MAC address to block or permit a computer within the home
network.
When you enable MAC filtering, the 3101 serves as a firewall that works on Layer 2. Click
MAC Fil-
tering (
Figure 78
)
in the
Security
menu to configure MAC frame filtering.
Note
MAC Filtering is only effective on ATM PVCs configured in Bridge
mode. If the ATM PVC is configured in another routing mode (such
as PPPoE mode), MAC Filtering will not be available in the Security
menu.
