•
logical-system-name—The name of the logical system, if the receiving interface is in a
logical system.
•
mac-address—The client MAC address, in a string of the format xxxx.xxxx.xxxx.
For DHCPv6 clients, because the DHCPv6 packet format has no specific field for the
client MAC address, the MAC address is derived from among several sources with the
following priority:
•
Client DUID Type 1 or Type 3.
•
Option 79 (client link-layer address), if present.
•
The packet source address if the client is directly connected.
•
The link local address.

NOTE: For DHCP relay agent, the option 82 value used in creating the
username is based on the option 82 value that is encoded in the outgoing
(relayed) PDU.
