IP Configuration - Link150 UG

Description

This page allows to configure the IP parameters including IPv4, IPv6, and DNS settings.

IPConfiguration Procedure

Step	Action	Result
1	From the Link150 menu bar, click Settings.	Opens the Settings menu.
2	From the Settings menu, in the Communication submenu, click IP Configuration.	Displays the IP parameters settings.
3	Enter IPv4, IPv6, and DNS parameters.	Enters the IPv4, IPv6, and DNS parameters.
4	Click Apply Changes.	Updates IP configuration settings of Link150 gateway.

IPv4 Configuration

Parameter	Description	Settings
Automatic	Used to select the mode for assigning IPv4 parameters. Obtain IPv4 parameters automatically using BOOTP or DHCP.	DHCP (Factory setting) BOOTP
Manual IP Address	Used to enter the static IP address of the Link150 gateway.	169.254.X.Y (Factory setting) NOTE: X and Y are the decimal equivalent of last two hexadecimal bytes of Link150 Mac address (found on the Link150 label).
Manual Subnet Mask	Used to enter the Ethernet IP subnet mask address of your network.	255.255.0.0 (Factory setting)
Manual Default Gateway	Used to enter the gateway (router) IP address used for wide area network (WAN) communication.	169.254.2.1 (Factory setting)

IPv6 Configuration

Parameter	Description	Settings
Enable	Defines the IPv6 configuration.	Enabled (Factory setting)
IPv6 Link-local Address	Displays the IP address in IPv6 format. You can use this IP address to open the Link150 homepage.	–

DNS

Parameter	Description	Setting
Obtain DNS Addresses Automatically via DHCP/BOOTP	Defines the dynamic behavior of the DNS server address configuration. Used to obtain the IP address from the DNS server automatically. NOTE: Domain Name System (DNS) is the naming system for PCs and devices connected to a local area network (LAN) or the Internet.	–
Manual Primary DNS Server	Defines the IPv4 address of the primary DNS server.	–
Manual Secondary DNS Server	Defines the IPv4 address of the secondary DNS server. Used to perform a DNS resolution when the resolution fails with the primary DNS server.	–

Duplicate IP Address Detection

While connected to your network, the Link150 gateway publishes its IP address. To avoid any duplicate IP address conflicts, the Link150 gateway uses the address resolution protocol (ARP) to see if any other device on your network is using the same IP address. The table below explains how the Link150 gateway handles a duplicate IP address when it is detected.

Duplicate IP Address Scenario

Scenario	Duplicate IP Handling	Network Status LED
Ethernet link detected	Reverts to the default IP address, subnet mask, and gateway address. ARP requests are sent once every 15 seconds until the IP address is available. Link150 gateway uses the IP address when it is available.	Steady red
Manual address change	Reverts to the default IP address, subnet mask, and gateway address. The ARP requests are sent once every 15 seconds until the IP address is available. The Link150 gateway uses the IP address when it is available.	Steady red
Receives an ARP request	If more than one ARP request is detected within 10 seconds, initiate the process to reacquire the IP.	OFF
