PLANET WGSW-52040 - Manual (Page 516)

32-56
This command is used to set the reforward policy of the system when receiving DHCPv6 packets with option 38,
among which the drop mode means that the system simply discards it with option 38, keep mode means that the
system keeps option 38 unchanged and forwards the packets to the server and replace mode means that the
system replaces option 38 of current packets with its own before forwarding it to the server. The no operation of this
command sets the reforward policy of DHCPv6 packets with option 38 as replace.
Parameters:
None.
Default:
Using replace mode to replace option 38 of current packets with system’s own.
Command Mode:
Global configuration mode
Usage Guide:
Since DHCPv6 client packets may already include option 38 information, corresponding processing policy of
DHCPv6 SNOOPING is requested to develop. If the reforward policy is set as replace, option 38 has to be enabled
in advance. The system disables option 38 of DHCPv6 SNOOPING by default.
Example:
Set the reforward policy of DHCPv6 packets with option 38 as keep for DHCPv6 SNOOPING.
Switch(Config)# ipv6 dhcp snooping subscriber-id policy keep.
