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, VLAN or loopback 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.
NOTE The device software consumes one VLAN ID (VID) for every IP
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:
STEP 1 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.
- Dynamic IP Address—Received from DHCP server.
- Static—Entered manually.
• IP Address—Configured IP address for the interface.
• Mask—Configured IP address mask.
• Status—Results of the IP address duplication check.
- Tenta t i v e —There is no final result for the IP address duplication check.
- Valid—The IP address collision check was completed, and no IP address
collision was detected.
- Valid-Duplicated—The IP address duplication check was completed,
and a duplicate IP address was detected.
- Duplicated—A duplicated IP address was detected for the default IP
address.
