Strange IPV6 related behaviour shown by a XMG1915-10E configured for DHCPV6
Latest firmware V4.80(ACGO.1)20240305 | 03/05/2024
IPV6 configured for DHCPV6 (VLAN 1), Fritz!Box as DHCPV6 server, which assigns DNS, IA-PD, and IA-NA; Fritz!Box also assigning ULAs for fd00::
IPV6 client setup for the XMG1915-10E with IA-NA, Rapid Commit, DNS, and Domain List set
IPV6 router discovery configured for VLAN 1 with both: M and O flags set
With this setup, IPV6 seems to work fine, with two exceptions:
1. The switch seems not to acquire an fd00 address from the Fritz!Box, although the Fritz!Box is set to assign ULAs for the IPV6 prefix fd00::
I can log in to the switch with its fe80 address but not with the corresponding fd00 one;
2. With the above setup, i.e., IPV6 enabled and working, and the switch configured as DHCPV6 client,
when I click the "Restart DHCPV6 client" button in the IPv6 Status —> IPv6 Interface Details window (this window says BOTH: "Static IPV6 active ON" and "DHCPV6 Client active ON"), the switch shows the following irritating message:
"Error: should enable ipv6 and dhcp6 client in this vlan"
and does not seem to restart the client
Any idea why those two things happen?
Maybe due to bugs in the latest firmware?

Hi @cbeckstein
Regarding the issue you mentioned on this thread:
The switch seems not to acquire an fd00 address from the Fritz!Box, although the Fritz!Box is set to assign ULAs for the IPV6 prefix fd00::
The switch does not have any limitations for the fd00:: subnet. Since we do not have a Fritz!Box on our site, we would require more time to conduct a lab test and identify the root cause of this issue.
With the above setup, i.e., IPV6 enabled and working, and the switch configured as DHCPV6 client,
when I click the "Restart DHCPV6 client" button in the IPv6 Status —> IPv6 Interface Details window (this window says BOTH: "Static IPV6 active ON" and "DHCPV6 Client active ON"), the switch shows the following irritating message:
"Error: should enable ipv6 and dhcp6 client in this vlan"
and does not seem to restart the client
We have confirmed that this is a bug. We are currently working on a solution for it. If there is any progress, we will update you soon.

Hi @cbeckstein
Since we don’t have a Fritz!Box on our site, we are trying to assign an IPv6 fd00:: address to the switch via a virtual server to replicate the scenario. Accessing it poses no problem.
Regarding this issue, we suggest seeking support from your Fritz!Box for further assistance.
As for the bug with "Restart DHCPV6 client," we will fix it in the next official firmware release. Stay tuned to the
for the latest firmware release.Kay
