Chapter 19 MAC Limit 19.2.2 MAC Limit: VLAN Security Select VLAN Security and click Apply in the MAC Limit screen to display VLAN security setting as shown. Figure 113 MAC Limit: VLAN Security The following table describes the labels shown after you select the VLAN Security in this screen. Table 75 MAC Limit: VLAN Security LABEL DESCRIPTION VLAN ID This field displays available VLAN IDs configured in this switch. Limited Number of Learned MAC Address Use this field to limit the number of (dynamic) MAC addresses learned in the same VLAN network. For example, if you set this field to "5" on VLAN 2, then only the devices with the first five learned MAC addresses can access VLAN 2 at any one time. A sixth device would have to wait until one of the five learned MAC addresses aged out. MAC address aging time can be set in the Basic Setting > Switch Setup screen. The valid range is from 0 to 16K (16384 bytes). "0" means this feature is disabled, so the switch will learn MAC addresses up to the global limit of 16K. VES1724-56 User's Guide 193
