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:
| Primary Address | Define the IP address for the VLAN associated virtual interface. Select DHCP, IP Address, ZEROCONF, or <none> |
| IP Address or Subnet Mask | Select IP Address in the primary address option to activate the field. Type the virtual interface IP address |
| Secondary Zeroconf | Select Secondary Zeroconf to provide 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 |
| DHCP Options | Select DHCP Options to allow DHCP to provide the IP address for the virtual interface |
| Secondary Address | Select Add 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 |
| DHCP Relay | Use DHCP Relay to set the DHCP relay server configuration used with the virtual interface |
| Respond to DHCP Relay | Select Respond to DHCP Relay to allow the onboard DHCP server to respond to relayed DHCP packets on this interface |
| Addresses | Select Add to configure additional IP Address for DHCP Relay |
