176 Managing Static MAC Addresses
Section 5.5.4
Managing Static MAC Addresses
Static MAC addresses must be configured when the device is only able to receive frames, not transmit them.
They may also need to be configured if port security (if supported) must be enforced.
Prioritized MAC addresses are configured when traffic to or from a specific device on a LAN segment is to be
assigned a higher CoS priority than other devices on that LAN segment.
NOTE
A MAC address cannot be learned on a VLAN that has not been configured in the Static VLAN table. If
a frame with an unknown VLAN tag arrives on a secured port, it is considered a security violation and
ROS will generate a port security alarm.
The following sections describe how to configure and manage static MAC addresses:
• Section 5.5.4.1, “Viewing a List of Static MAC Addresses”
• Section 5.5.4.2, “Adding a Static MAC Address”
• Section 5.5.4.3, “Deleting a Static MAC Address”
