Automatic link-local IPv6 assignment on disabled interface
When you enable IPv6 on any of the device's Ethernet ports (
Network > Port A
or
Network > Port B
), the
device automatically assigns a link-local IPv6 address to each Ethernet port, even if the port is disabled. An
IP address that is assigned to a disabled Ethernet port may not be apparent on the web interface.

Link-local addresses
Link-local IPv6 addresses are generated using the MAC address of each physical interface, and are thus
unique per physical interface. No restrictions are imposed on link-local IPv6 addresses and all services
enabled on their corresponding global IPv6 addresses are available on the link-local address. They support
basic configuration and administration services (such as the web interface) but may not support full
functionality such as making and receiving calls. Full functionality is only guaranteed for the main global IPv6
address on each interface.

We recommend using a PC with a single network interface connected to the local subnet when trying to
access the MCU web UI using its link-local IPv6 address. Otherwise, login may fail since web browsers do
not support URL redirection for an address with a scope ID.
