server.
Figure 379 NETWORKING > DHCP > DHCPv6 Server > DHCPv6 Server Status
The following table describes the labels in this screen.
Table 251 NETWORKING > DHCP > DHCPv6 Relay > Add/Edit
LABEL DESCRIPTION
VID Enter the ID number of the VLAN to which the DHCPv6 server that will assign IP information
belongs here.
Helper Address Enter the IPv6 address of the DHCPv6 server that will assign IP information here.
An 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address ‘2001:0db8:1a2b:0015:0000:0000:1a2f:0000
’
.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So ‘2001:0db8:1a2b:0015:0000:0000:1a2f:0000’ can
be written as ‘2001:db8:1a2b:15:0:0:1a2f:0’.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double
colon can only appear once in an IPv6 address. So
‘2001:0db8:0000:0000:1a2f:0000:0000:0015’ can be written as
‘2001:0db8::1a2f:0000:0000:0015’, ‘2001:0db8:0000:0000:1a2f::0015’, ‘2001:db8::1a2f:0:0:15’
or ‘2001:db8:0:0:1a2f::15’.
Interface ID Enable the switch button to have the Switch add the interface-ID option in the DHCPv6 requests
from the clients in the specified VLAN before the Switch forwards them to a DHCPv6 server.
Remote ID Enter a string of up to 64 printable ASCII characters (except [ ? ], [ | ], [ ' ], [ " ] or [ , ]) to be
carried in the remote-ID option. The Switch adds the remote-ID option in the DHCPv6 requests
from the clients in the specified VLAN before the Switch forwards them to a DHCPv6 server.
Apply Click Apply to save 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.
Clear Click Clear to clear the fields to the factory defaults.
Cancel Click Cancel to not save the configuration you make and return to the last screen.

VID This field displays the VLAN ID to which the DHCP server belongs.
Information This field displays Yes when the entry supports display of the refresh time and DNS server; it
shows No when it does not.
