If a dynamic IP address is retrieved from the DHCP server, select those of the
following fields that are enabled:
•
Renew IP Address Now—The device dynamic IP address can be renewed
any time after it is assigned by a DHCP server. Note that depending on your
DHCP server configuration, the device might receive a new IP address after
the renewal that requires setting the web-based configuration utility to the
new IP address.

Click Apply. The IPv4 interface settings are written to the Running Configuration
file.
Defining IPv4 Interface in Layer 3 System Mode
The IPv4 Interface page is used when the device is in Layer 3 system mode. This
mode enables configuring multiple IP addresses for device management, and
provides routing services.
The IP address can be configured on a port, a LAG, or VLAN interface.
Operating in Layer 3 mode, the device routes traffic between the directly-
attached IP subnets configured on the device. The device continues to bridge
traffic between devices in the same VLAN. Additional IPv4 routes for routing to
non-directly attached subnets can be configured in the IPv4 Static Routes page.
The device software consumes one VLAN ID (VID) for every IP
NOTE
address configured on a port or LAG. The device takes the first VID that is
not used starting from 4094.
To configure the IPv4 addresses:
Click IP Configuration > IPv4 Management and Interfaces > IPv4 Interface.
This page displays the following fields in the IPv4 Interface Table:
•
Interface—Interface for which the IP address is defined.
•
IP Address Type—IP address defined as static or DHCP.
-
Static—Entered manually.
-
DHCP—Received from DHCP server.
