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 DUID 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. You can enter up to 64 printable ASCII
characters except [ ? ], [ | ], [ ' ], [ " ] or [ , ].
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.
