Use the textual interface description instead of the interface identifier in the DHCP base
option 82 Agent Circuit ID (suboption 1) or Agent Remote ID (suboption 2) information,
or in the DHCPv6 option 18 (Relay Agent Interface ID) or option 37 (Relay Agent Remote
ID) information in DHCP packets that the DHCP relay agent sends to a DHCP server.
NOTE: For integrated routing and bridging (IRB) interfaces, the option 82
field must be able to uniquely identify the incoming interface based on either
the Agent Circuit ID or Agent Remote ID. You can modify the information in
the textual interface description to match the raw IFD (physical interface
without a subunit) name and configure the option 82 field to use the interface
description.
The textual description is configured using the
hierarchy level. If you specify that the textual description be used and
interface-name]
no description is configured for the interface, DHCP relay defaults to using the Layer 2
interface name. When you use the interface description rather than the interface name,
