Planet SGS-6341 Series Command Manual page 436

Usage Guide:
Only after this command is configured, DHCPv6 relay agent can add option 37 in DHCPv6 request
packets before sending it to server or next relay agent. Make sure that DHCPv6 service has been
enabled before execute this command.
Example:
Enable the switch relay to support option 37.
Switch(Config)#service dhcpv6
Switch(Config)#ipv6 dhcp relay remote-id option
29.1.6 ipv6 dhcp relay subscriber-id
Command:
ipv6 dhcp relay subscriber-id <subscriber-id>
no ipv6 dhcp relay subscriber-id
Function:
This command is used to set the form of adding option 38 in received DHCPv6 request packets, of
which <subscriber-id> is the subscriber-id in user-defined option 38 and it is a string with a length of
less than 128. The no operation of this command restores subscriber-id in option 38 to vlan name
together with port name such as "Vlan2+Ethernet1/0/2".
Parameters:
subscriber-id, user-defined content of option 38
Default:
Set subscriber-id in option 38 to vlan name together with port name.
Command Mode:
Interface configuration mode
Usage Guide:
Because the option 38 information added by switch may associate with third-party DHCPv6 servers,
users can specify the subscriber-id content based on server condition when standard subscriber-id
of the switch cannot satisfy the demand of server. The vlan name together with physical port name
is used as the subscriber-id in option 38 by default.
Example:
Enable abc as the subscriber-id of DHCPv6 option 38.
Switch(Config-if-vlan1)# ipv6 dhcp relay subscriber-id abc
29.1.7 ipv6 dhcp relay subscriber-id option
