IP and MAC Binding
When the device is configured as a DHCP server or for DHCP relay, you can bind
static IP addresses to up to 100 network devices, such as a web server or an FTP
server. Binding does not assign an IP address to a device. You should ensure that
each device bound to a static IP address in the IP & MAC binding table is
configured to use a static IP address.
Typically the MAC address of a device physically appears on a label on the
bottom panel or back panel of a device.
To open this page, select DHCP > IP & MAC Binding in the navigation tree.
Bind IP Addresses by Discovery
To bind known IP addresses to MAC addresses and name the binding:
STEP 1 Click Show Unknown MAC Addresses. The IP & MAC Binding Table appears. If
the web browser displays a message about the pop-up window, allow the
blocked content.
The devices are listed by the IP address and the MAC address. If needed, click
Refresh to update the data.
STEP 2 Enter a descriptive Name.
STEP 3 Check the Enable box. Alternatively, select all devices in the list by clicking the
check box at the top of the Enable column.
STEP 4 Click Save to add the devices to the Static IP list, or click Close to close the pop-
up window without adding the selected devices.
Bind IP Addresses Manually

•Static IP Address—Static IP address. You can enter 0.0.0.0 if you want the
router to assign a static IP address to this device.
•MAC Address—MAC address of the device. Enter the address without
punctuation.
•Name—Descriptive name for the device.
•Enable—Check this box to bind the static IP address to this device.
