Duplicate IP Address Detection

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

Duplicate IP Address Scenario

Scenario

Duplicate IP Detected

Network Status LED

Ethernet link detected

Reverts to the default IP address, subnet mask, and gateway address. ARP requests are sent every 15 seconds until the IP address is available. IFE interface 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 every 15 seconds until the IP address is available. The IFE interface uses the IP address when it is available.

Steady red
