5.2 DHCPv6 Features Supported by the S9300&S9300E
Currently, the S9300&S9300E supports only the DHCPv6 relay function, and cannot function
as the DHCPv6 server or client.

the DHCPv6 server through the link-scoped multicast address to obtain the IPv6 address and
other network configuration parameters. If the DHCPv6 server and the DHCPv6 client are
located on different links, the DHCPv6 relay agent is required to forward messages. In this case,
you do not need to deploy a DHCPv6 server on each link. The costs are thus saved and
concentrated management is implemented easily.

Link layer address
– DUID type: The value of the DUID type is 0x0001.
– Hardware type: The hardware type supported by the device is Ethernet and the value is
0x0006.
– Time: time when the DUID is generated. Before the DUID is generated, the system time
must be configured or the clock source is available.
– Link layer address: The value is the link layer address of any interface. The interface
has a unique link layer address. The link layer address is the MAC address.
