Configuration of MAC-Based Groups to VLAN on 300 Series Switches
A Media Access Control address (MAC address) is a unique identifier given to each network interface. Packets (i.e. messages from a device) can be placed in a VLAN group by their source MAC address. The information in a VLAN group is then sent to a designated VLAN. The 300 Series Managed Switches allow you to define several MAC-based VLAN groups. Once created, these VLAN groups can be assigned to specific ports/LAGs on the switch and forwarded to specific VLANs.
The objective of this document is to show you how to create MAC-based VLAN groups and map them to a specific interface (port/LAG).
Step 1. Log in to the web configuration utility and choose VLAN Management > VLAN Groups > MAC-Based Groups. The MAC-Based Groups page opens.
Step 2. Click Add to create a new MAC-based group. The Add MAC-Based Group window appears.
Step 3. In the MAC Address field, enter a MAC address that you want to configure to a VLAN group.
Step 4. Click the radio button that corresponds to the method you want to use in order to define the Prefix Mask. The prefix mask looks at a certain number of bits and then assigns the MAC address to a VLAN group.
• Host — The entire MAC address is looked at and put into a group. You can only group MAC addresses one at a time when you use host.
• Length — Only a section of the MAC address is looked at (from left to right) and then placed in a group. The lower the length number, the fewer bits are looked at. This means you can assign a large number of MAC addresses to a VLAN group at once. For example, all of the computers in your network are made by the same company.
Step 5. In the Group ID field, create and enter a VLAN group ID number with which to identify the MAC-Based VLAN group.
Step 6. Click Apply to create the MAC-based group and then click Close to exit the Add MAC-Based Group window.
