IPv4 is a connectionless protocol. It operates on a best effort delivery model that does not guarantee delivery or assures proper sequencing or avoidance of duplicate delivery (unlike TCP).
To configure the VLAN IPv4 configuration:
| Enable Zero Configuration | Zero configuration can be a means of providing a primary or secondary IP addresses for the virtual interface. Zero configuration (or zero config) is a wireless connection utility included with Microsoft Windows XP and later as a service dynamically selecting a network to connect based on a user's preferences and various default settings. Zero config can be used instead of a wireless network utility from the manufacturer of a computer's wireless networking device. This value is set to None by default. |
| Primary IP Address | Define the IP address for the VLAN associated virtual interface. |
| Use DHCP to Obtain IP | Select this option to allow DHCP to provide the IP address for the virtual interface. Selecting this option disables the Primary IP Address field. |
| Use DHCP to Obtain Gateway/DNS Servers | Select this option to allow DHCP to obtain a default gateway address and DNS resource for one virtual interface. This setting is disabled by default and only available when the Use DHCP to Obtain IP option is selected. |
| Secondary Addresses | Use this parameter to define additional IP addresses to associate with VLAN IDs. The address provided in this field is used if the primary IP address is unreachable. |
| Respond to DHCP Relay Packets | Select this option to allow the onboard DHCP server to respond to relayed DHCP packets on this interface. This setting is disabled by default. |
| DHCP Relay | Provide IP addresses for DHCP server relay resources. DHCP relays exchange messages between a DHCPv6 server and client. A client and relay agent exist on the same link. When A DHCP request is received from the client, the relay agent creates a relay forward message and sends it to a specified server address. If no addresses are specified, the relay agent forwards the message to all DHCP server relay multicast addresses. The server creates a relay reply and sends it back to the relay agent. The relay agent then sends back the response to the client. |
