client-id (DHCP Local Server)


Hierarchy Level


Specify that the client identifier (DHCP option 61) is concatenated with the username during the subscriber authentication or client authentication process.



By default, all headers that are part of the client identifier format in option 61 are included in the username string used for RADIUS authentication. Configure the exclude-headers option to exclude the use of headers in the username string.


By default, all components of the client identifier are converted to ASCII hex to encode the username. Configure the use-automatic-ascii-hex-encoding option to use ASCII hex encoding only if there are non-ASCII characters in the client identifier.

Use this option instead of the interface-name option when the outer VLAN tag is unique across the system and you do not need the underlying physical interface name to be part of the format.
