By default, when DHCP relay agent inserts option information in the packets sent to a
DHCP server, the options include the interface identifier. However, you can configure the
DHCP relay agent to include the textual description that is configured for the interface
instead of the interface identifier. You can use the textual description for either the logical
interface or the device interface.
You can include the textual interface description in the following DHCP options:
DHCPv4 option 82 Agent Circuit ID (suboption 1)
DHCPv4 option 82 Agent Remote ID (suboption 2)
DHCPv6 option 18 Relay Agent Interface-ID
DHCPv6 option 37 Relay Agent Remote-ID
