 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 user-defined

option 37 and it is a string with a length of less than 128. The no form of this 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.

 Example: Enable abc as remote-id of DHCPv6 option 37.
