18.1.12 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 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.
Parameters: remote-id, user-defined content of option 37.
Default: Using vlan MAC address as remote-id content by default such as
―00-01-ac-12-23‖ with ‗-‘ hyphen.
Command Mode: Port mode
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.
