29.1.14 ipv6 dhcp snooping remote-id policy
Command:
ipv6 dhcp snooping remote-id policy {drop | keep | replace}
no ipv6 dhcp snooping remote-id policy
Function:
This command is used to configure the reforward policy of the system when receiving DHCPv6
packets with option 37, among which the drop mode means that the system simply discards it with
option 37, keep mode means that the system keeps option 37 unchanged and forwards the packets
to the server and replace mode means that the system replaces option 37 of current packets with
its own before forwarding it to the server. The no operation of this command sets reforward policy of
DHCPv6 packets with option 37 as replace.
Default:
Using replace mode to replace option 37 of current packets with system’s own.
Command Mode:
Global configuration mode
Usage Guide:

policy of DHCPv6 SNOOPING is required to develop. If the forwarding policy is set as replace,
option 37 has to be enabled in advance. Use replace mode to replace option 37 of current packets
with system’s own by default.
Example:
Configure the reforward policy of DHCPv6 packets with option 37 as keep for DHCPv6 SNOOPING.
Switch(Config)# ipv6 dhcp snooping remote-id policy keep
