Used to configure the checking mechanism of DHCP relay agent information option 82 of the
switch.
config dhcp_relay option_82 check [enable | disable]
This command is used to configure the checking mechanism of DHCP/BOOTP relay agent
information option 82 of the switch.
enable – When the field is toggled to enable, the relay agent will check the validity of the
packet's option 82 field. If the switch receives a packet that contains the option 82 field from a
DHCP client, the switch drops the packet because it is invalid. In packets received from
DHCP servers, the relay agent will drop invalid messages.
disable − When the field is toggled to disable, the relay agent will not check the validity of the
packet's option 82 field.
Only Administrator and Operator-level users can issue this command.

config dhcp_relay option_82 policy [replace | drop | keep]

option 82 of the switch.
replace − The option 82 field will be replaced if the option 82 field already exists in the packet
received from the DHCP client.
drop − The packet will be dropped if the option 82 field already exists in the packet received
from the DHCP client.
keep − The option 82 field will be retained if the option 82 field already exists in the packet
received from the DHCP client.
Only Administrator and Operator-level users can issue this command.
