DHCPv6 Relay & Client

DHCPv6 is a networking protocol for configuring IPv6 hosts with IP addresses, IP prefixes or other configuration attributes required on an IPv6 network. DHCPv6 relay agents receive messages from clients and forward them a DHCPv6 server. The server sends responses back to the relay agent and the relay agent sends the responses to the client on the local link.

To view the controller or service platform's DHCPv6 relay configuration:

Select the Statistics menu from the Web UI.
Expand the System node from the navigation pane (on the left-hand side of the screen). The System node expands to display the RF Domains created within the managed network.
Expand the RF Domain node.
Select the Wireless Controller node from the left navigation pane.

Select DHCP Relay & Client from the left-hand side of the UI.

The Statistics > Controller > DHCP Relay & Client screen displays in the right-hand pane.
