Usage Guide:
Only after this command is configured, DHCPv6 SNOOPING can add option 37 in DHCPv6 packets before sending
it to server or relay agent. Make sure that DHCPv6 SNOOPING has been enabled before execute this command.
The system disables option 37 of DHCPv6 SNOOPING by default.
Example:
Enable option 37 in DHCPv6 SNOOPING.
Switch(Config)#ipv6 dhcp snooping enable
Switch(Config)#ipv6 dhcp snooping remote-id option
34.1.14 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.
Parameters:
None.
Default:
Using replace mode to replace option 37 of current packets with system's own.
Command Mode:
Global configuration mode
Usage Guide:
Since DHCPv6 client packets may already include option 37 information, corresponding processing 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.
