Defining an IPv4 Interface in Layer 2 System Mode To manage the device by using the web-based configuration utility, the IPv4
device management IP address must be defined and known. The device IP
address can be manually configured or automatically taken from a DHCP server.
To configure the IPv4 device IP address:
STEP 1 Click Administration > Management Interface > IPv4 Interface.
STEP 2 Enter values for the following fields:
•Management VLAN—Select the Management VLAN used to access the
device through telnet or the Web GUI. VLAN1 is the default Management
VLAN.
•IP Address Type—Select one of the following options:
-
Dynamic
—Discover the IP address using DHCP from the management
VLAN.
-
Static

an DH CP cli en t. If D HCP Op tio n 1 2 is rec ei ved fr om a DH CP s er ver, it i s s ave d

device. The DHCP server must be configured to send option 12 regardless
of what is requested in order to make use of this feature.
If a static IP address is used, configure the following fields.
•IP Address—Enter the IP address, and configure one of the following Mask
fields:
-Network Mask—Select and enter the IP address mask.

gateway IP address from the interface.

status.
NOTE If the device is not configured with a default gateway, it cannot
communicate with other devices that are not in the same IP subnet.
