from DHCPv6 server.
Start interface ID: enter the start interface ID. The IPv6 address composed of two parts, thus, the
prefix and the interface ID. Interface is like the Host ID compared to IPv4.
End interface ID: enter the end interface ID.
Note: Interface ID does NOT support ZERO COMPRESSION "::". Please enter the complete
information.
For example: Please enter "0:0:0:2" instead of "::2".
Leased Time (hour): the leased time, similar to leased time in DHCPv4, is a time limit assigned to
clients, when expires, the assigned ID will be recycled and reassigned.
Issue Router Advertisement: check whether to enable issue Router Advertisement feature. It is to
send Router Advertisement messages periodically.
MLD snooping: similar to IGMP snooping, listens in on the MLD conversation between hosts and
routers by processing MLD packets sent in a multicast network, and it analyzes all MLD packets
between hosts and the connected multicast routers in the network. Without MLD snooping, multicast
traffic is treated in the same manner as broadcast traffic - that is, it is forwarded to all ports. With
MLD snooping, multicast traffic of a group is only forwarded to ports that have members of that
group.
Standard Mode: In standard mode, multicast traffic will flood to all bridge ports when no
client subscribes to a multicast group.
Blocking Mode: In blocking mode, the multicast data will be blocked when there is no
client subscribes to a multicast group, it won't flood to the bridge ports.
Stateless and Stateful IPv6 address Configuration
Stateless: two methods can be adopted.
With DHCPv6 disabled, but Issue Router Advertisement Enabled
With this method, the PCs in LAN are configured through RA mode, thus, the PCs in LAN are
configured through RA mode, to obtain the prefix message and generate an address using a
combination of locally available information (MAC address) and information (prefix) advertised by
routers.
With both DHCPv6 and Issue Router Advertisement Enabled
With this method, the PCs' addresses in LAN are configured like above method, but they can
obtain such information like DNS from DHCPv6 Server.
