Switch(Config)# ipv6 dhcp server subscriber-id option
30.1.12 ipv6 dhcp snooping remote-id
Command: ipv6 dhcp snooping remote-id <remote-id>
no ipv6 dhcp snooping remote-id
Function: This command is used to set the form of adding option 37 in received
DHCPv6 request packets, of which <remote-id> is the content of remote-id in

command restores remote-id in option 37 to enterprise-number together with vlan MAC
address.

Usage Guide: Because option 37 information added by switch may associate with
third-party DHCPv6 servers, users can specify remote-id content based on server
condition when standard remote-id of the switch cannot satisfy the demand of server.
The enterprise-number together with vlan MAC address is used as the remote-id by
default.
