Managing MAC Address Table Security Configurations 3.1.2 Limiting the Number of MAC Addresses in VLANs Choose the menu Switching > MAC Address > MAC VLAN Security to load the following page. Figure 3-2 Limiting the Number of MAC Addresses in VLANs Follow these steps to limit the number of MAC addresses in VLANs: 1) Enter the VLAN ID to limit the number of MAC addresses that can be learned in the specified VLAN. VLAN ID Specify an existing VLAN in which you want to limit the number of MAC addresses. 2) Enter your desired value in Max Learned MAC to set a threshold. Max Learned MAC Set the maximum number of MAC addresses in the specific VLAN. It ranges from 0 to 16383. You can control the available address table space by setting maximum learned MAC number for VLANs. However, an improper maximum number can cause unnecessary floods in the network or a waste of address table space. Therefore, before you set the number limit, please be sure you are familiar with the network topology and the switch system configuration. 3) Choose the mode that the switch adopts when the maximum number of MAC addresses in the specified VLAN is exceeded. Drop Packets of new source MAC addresses in the VLAN will be dropped when the maximum number of MAC addresses in the specified VLAN is exceeded. Forward Packets of new source MAC addresses will be forwarded but the addresses will not be learned when the maximum number of MAC addresses in the specified VLAN is exceeded. Disable 4) Click Create. The number limit on the VLAN is not valid, and the switch follows the original forwarding rules. Configuration Guide 145
