Defining IPv4 Interface when the Switch is in Layer 3 Mode

The IPv4 Interface page is used when the switch is in Layer 3 mode. This mode enables configuring multiple IP addresses for switch 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 switch routes traffic between the directly-attached IP subnets configured on the switch. The switch 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 switch software consumes one VLAN ID (VID) for every IP address configured on a port or LAG. The switch takes the first VID that is not used starting from 4094.

To configure the IPv4 addresses:

  1. Click IP Configuration > Management and IP Interface (Layer 3) > IPv4 Interface. The IPv4 Interface page opens.
  2. This page displays the following fields:

    • 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”.
  3. Click Add. The Add IPv4 Interface page opens.
  4. Select one of the following fields:
    • Interface--Select Port, LAG, or VLAN as the interface associated with this IP configuration, and select a value for the 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.
  5. If Static Address was selected, enter the IP Address for this interface.
  6. Enter the Network Mask or Prefix Length for this IP address.
    • Network Mask--IP mask for this address.
    • Prefix Length--Length of the IPv4 prefix.
  7. Click Apply. The IPv4 address settings are defined, and the Running Configuration file is updated.
