Dhcpv6 Snooping Support For Option 37; Dhcpv6 Snooping Configuration Task List - HPE FlexNetwork 10500 Series Configuration Manual

DHCPv6 snooping support for Option 37

Option 37, also called the remote-ID option, is used to identify the client.
The DHCPv6 snooping device adds Option 37 to the received DHCPv6 request message before
forwarding it to the DHCPv6 server. This option provides client information about address allocation.
