• sysname indicates using the device name of a node as the node identifier.
• user-defined node-identifier indicates using a specific character string as the node identifier, in

Usage guidelines
If configuring the handling strategy of the DHCP relay agent as replace, you need to configure a
padding format of Option 82. If the handling strategy is keep or drop, you need not configure any
padding format.
If sub-option 1 (node identifier) of Option 82 is padded with the device name (sysname) of a node, the
device name must contain no spaces. Otherwise, the DHCP relay agent drop the message.
