Parameters

drop: Drops DHCP messages that contain Option 82 messages.

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 as keep.

<Sysname> system-view
[Sysname] interface vlan-interface 10
[Sysname-Vlan-interface10] dhcp relay information enable
