Duplicate IP Address Detection | While connected to your network, the ETG publishes its IP address. To | ||
| avoid any duplicate IP address conflicts, the ETG uses the Address | ||
| Resolution Protocol (ARP) to see if any other device on your network is | ||
| using the same IP address. Table 3 below explains how the ETG handles a | ||
| duplicate IP address when it is detected. |

| address. ARP requests are sent every |
|
| Ethernet Link Detected |
| |
| 15 seconds until the IP address is |
| |
|
|
| |
|
| available. When the IP address |
|
|
| becomes available, the ETG will use |
|
|
| it. |
|
|
|
|
|
| Manual Address Change | ETG keeps it’s previous IP address |
|
|
| and displays a message indicating |
|
|
| that the IP address is already in use |
|
|
| by another device. |

| address if a connected device sends |
|
|
| four ARP requests for the ETG’s IP |

|
| address. The ETG will send ARP |
|
|
| requests every 15 seconds until the |
|
|
| IP address is available again. When |
|
|
| the IP address becomes available, |
|
|
| the ETG will use it. |
