Table 213 IP Application > DHCP > DHCPv6 > Prefix Delegation
LABEL DESCRIPTION
Client DUID Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for
identification when they are exchanging DHCPv6 messages. The DUI D is generated from the
MAC address, time, vendor assigned ID and/or the vendor's private enterprise number
registered with the IANA. Type the client DUID for the devices connected to the Switch in
this field.
Client Name Type a name to identify the DHCPv6 client in this field.
VID Type the ID number of the VLAN to which the DHCPv6 client belongs here.
Prefix Address IPv6 uses an address prefix to represent the network address. An IPv6 prefix length
specifies how many most significant bits (start from the left) in the address compose the
network address. The prefix length is written as “/ x” where x is a number. For example,
‘2001: db8:1a2b: 15: :1a2f: 0/ 32’ is a prefix address with prefix length.
/32 means that the first 32 bits (‘2001: db8’) from the left is the network prefix.
Type the prefix address in this field. For example, type ‘2001:db8: 1a2b: 15::1a2f: 0’
Prefix Length Type the prefix length in this field. For example, type 32.
Add Click this to create a new entry or to update an existing one.
This saves your changes to the Switch’s run-time memory. The Switch loses these changes if
it is turned off or loses power, so use the Save link on the top navigation panel to save your
changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to reset the fields to their last saved values.
Clear Click Clear to reset the fields to the factory defaults.
Index This field displays a sequential number for each entry. Click an index number to change its
settings.
Client DUID This field displays the client DHCP Unique IDentifier (DUID) which uniquely identifies the
client.
Client Name This field displays a name to identify the DHCPv6 client.
VID This field displays the ID number of the VLAN to which the DHCPv6 client belongs.
