● IPv6 Address Type
Displays the address type. The following values are possible:
– Unicast
– Link Local
● Address Collision Detection Status
In Address Autoconfiguration (SLAAC), the "Address Collision Detection Status" function
prevents IPv6 addresses from being assigned twice. The device can only use free IPv6
addresses during autoconfiguration.
When the function is activated, the check via NDP takes place automatically.
Note
The function does not run a cyclic check.
This column shows the current status of the function. The following values are possible:
– Tentative
– Conflict
– Complete
– Down
Procedure

2. Click the "Create" button. In the table an entry with the interface is created and the
automatically formed link-local IPv6 address is displayed.
Assign link-local address
1. Enable IPv6.
2. In "IPv6 Address", enter the link-local address, e.g. FE80::21B:1BFF:FE40:9155
3. Enter "128" in "Prefix Length".
4. For "IPv6 Address Type" select the entry "Link Local".

This status indicates that the selected IPv6 address is being checked. The device sends
a neighbor solicitation message to the selected IPv6 address.
This status indicates that the IPv6 address is already being used. In this case, a neighbor
advertisement message with the selected IPv6 address is returned to the device. The
device forms a new IPv6 address and checks this again.
This status indicates that the selected IPv6 address can be used. In this case, the device
did not receive feedback within a period of time and assumes that the IPv6 address is not
yet assigned.
This status indicates that the interface is not active. No check is carried out.
