The following table describes the labels in this screen.
63.6 DHCPv6 Relay
A DHCPv6 relay agent is on the same network as the DHCPv6 clients and helps forward messages
between the DHCPv6 server (that is in another network) and the DHCPv6 clients.
The DHCPv6 relay agent can add the remote identification (remote-ID) option and the interface-ID
option to the Relay-Forward DHCPv6 messages. The remote-ID option carries a user-defined string, such
as the system name. The interface-ID option provides slot number, port information and the VLAN ID to
the DHCPv6 server. The remote-ID option (if any) is stripped from the Relay-Reply messages before the
relay agent sends the packets to the clients. The DHCPv6 server copies the interface-ID option from the
Relay-Forward message into the Relay-Reply message and sends it to the relay agent. The interface-ID
should not change even after the relay agent restarts.
Use this screen to view and configure DHCPv6 relay settings for a specific VLAN on the Switch. Click
NETWORKING > DHCP > DHCPv6 Relay in the navigation panel to display the screen as shown.

LABEL DESCRIPTION
VID Enter the ID number of the VLAN you want to configure here.
Port Enter the number of ports to which you want to apply the specified DHCP option 82 profile.
You can enter multiple ports separated by (no space) comma (,) or hyphen (-) for a range. For
example, enter “3-5” for ports 3, 4, and 5. Enter “3,5,7” for ports 3, 5, and 7.
In Stacking mode, the first number represents the slot and the second the port number. Enter 1/
1-1/24,2/28 for ports 1 to 24 for the Switch in slot 1 and port 28 for the Switch in slot 2, for
example.
Option 82 Profile Select a pre-defined DHCP option 82 profile that the Switch applies to the specified ports in this
VLAN. The Switch adds the Circuit ID sub-option and/or Remote ID sub-option specified in the
profile to DHCP requests that it relays to a DHCP server.
The profile you select here has priority over the one you select in the NETWORKING > DHCP >
DHCPv4 Relay > DHCP Relay VLAN Setting (the DHCP Relay VLAN Setting section)> Add/Edit
screen.
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.
