This string gives the display name assigned to a specific DHCP relay rule, letting an administrator identify which forwarding policy a given table row represents. It makes it possible to read the accompanying hit and rejection counters in context, such as knowing they apply to the 'Guest-VLAN-Relay' rule rather than another one. For example, an admin auditing DHCP behavior for a guest Wi-Fi VLAN would look up this name to confirm which rule is handling that segment's lease requests.
