Configure a MAC-Based VLAN
The MAC-Based VLAN feature allows incoming untagged packets to be assigned to a VLAN
and thus classify traffic based on the source MAC address of the packet.
You define a MAC to VLAN mapping by configuring an entry in the MAC to VLAN table. An
entry is specified through a source MAC address and the desired VLAN ID. The MAC to
VLAN configurations are shared across all ports of the device (that is, there is a system-wide
table with MAC address to VLAN ID mappings).
When untagged or priority-tagged packets arrive at the switch and entries exist in the MAC to
VLAN table, the source MAC address of the packet is looked up. If an entry is found, the
corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it
maintains this value; otherwise, the priority is set to zero.
The assigned VLAN ID is verified
against the VLAN table, if the VLAN is valid, ingress processing on the packet continues;
otherwise the packet is dropped.
This implies that the user is allowed to configure a MAC
address mapping to a VLAN that was not created on the system.
To add or delete a MAC-based VLAN:
1. Launch a web browser.
2. In the address field of your web browser, enter the IP address of the switch.
The login window opens.
3. Enter the user name and password.
The default admin user name is
admin and the default admin password is blank, that is,
do not enter a password.
4. Click the Login button.
The System Information page displays.
5. Select Switching> VLAN >
