Release Information Statement introduced in Junos OS Release 9.1.
Statement introduced in Junos OS Release 12.3R2 for EX Series switches.
Support for DHCPv6 added in Junos OS Release 17.2 for MX Series Routers.
Description Specify that the MAC address from the client PDU be concatenated with the username
during the subscriber authentication or DHCP client authentication process.
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.
Required Privilege
