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.

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:

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.
• Static—Entered manually.
• DHCP—Received from DHCP server.
• IP Address—Configured IP address for the interface.
• Mask—Configured IP address mask.
• Status—Results of the IP address duplication check.
• Tentative—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.
• Delayed—The assignment of the IP address is delayed for 60 second if DHCP Client is enabled on startup in order to give time to discover DHCP address.
• Not Received—Relevant for DHCP Address. When a DCHP Client starts a discovery process, it assigns a dummy IP address 0.0.0.0 before the real address is obtained. This dummy address has the status of “Not Received”.
2. Click Add.
3. Select one of the following fields:
• Interface—Select Port, LAG, or VLAN as the interface associated with this IP configuration, and select an interface from the list.
• IP Address Type—Select one of the following options:
• Dynamic IP Address—Receive the IP address from a DHCP server.
• Static IP Address—Enter the IP address.
4. If Static Address was selected, enter the IP Address for this interface.
5. If Static Address was selected, enter one of the following:
• Network Mask—IP mask for this address.
• Prefix Length—Length of the IPv4 prefix.
6. Click Apply. The IPv4 address settings are written to the Running Configuration file.
