Switch(Config)#ipv6 dhcp snooping subscriber-id option
29.1.17 ipv6 dhcp snooping subscriber-id policy
Command:
ipv6 dhcp snooping subscriber-id policy {drop | keep | replace}
no ipv6 dhcp snooping subscriber-id policy
Function:
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.
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.
