Parameters
drop: Drops DHCP messages that contain Option 82.
keep: Keeps the original Option 82 intact.
replace: Replaces the original Option 82 with the configured Option 82.
Usage guidelines
This command takes effect only on DHCP requests that contain Option 82.
When enabled to support Option 82, the DHCP relay agent always adds Option 82 into DHCP
requests that do not contain Option 82 before forwarding the requests to the DHCP.
Examples
# Specify the handling strategy for Option 82 in request messages as keep.

Usage guidelines
This command enables the DHCP snooping device to generate DHCP snooping logs and send them
to the information center. For information about the log destination and output rule configuration in
the information center, see Network Management and Monitoring Configuration Guide.
As a best practice, disable this feature if the log generation affects the device performance.
