Controls whether the DHCP server uses the client?s MAC
address as the only client identifier. The standard behavior,
as specified in RFC 2132, is to use the client-id option (if it
is present) as the unique client identifier. Default is false
(disable).
CAUTION: Use this attribute with care. When enabled, it
precludes a MAC address from getting multiple IP addresses per
network. It forces the server to use a Client-Identifier (CID)
created from the MAC address instead of the RFC described
client-id contained in the request. This can preclude newer
devices that take multiple IP addresses. Enabling, or later
disabling, this attribute can also have an operational impact.
Clients that originally obtain addresses through a client-id
cannot renew them once they are assigned attributes based on
a MAC address.
map-radius-class enumint(none=0, map-as-tag=1, map-as-class=2, append-to-tags=3) default = 0
Controls how to map the radius attribute, if present,
in the client request relay-agent option:
0 none Ignores the radius class name default
1 map-as-tag Maps the radius class to selection-tags
2 map-as-class Maps the radius class directly to a
client-class name
3 append-to-tags Appends the radius class to the
selection-tags
map-radius-pool-name enumint(none=0, map-as-tag=1, map-as-class=2, append-to-tags=3)
default = 0
Controls use of the radius framed-pool attribute, if present,
in a client relay-agent option.
0 none Ignores the framed-pool attribute
1 map-as-tag Maps the framed-pool attribute to
selection-tags
2 map-as-class Maps framed-pool attribute directly to a
client-class name
3 append-to-tags Appends the user-class-id to the
selection-tags
map-user-class-id enumint(none=0, map-as-tag=1, map-as-class=2, append-to-tags=3) default = 0
Controls how the server uses the user-class-id option. Values are:
0 none Ignores the user class-id(default)
1 map-as-tag Maps the user-class-id to selection-tags
2 map-as-class Maps user-class-id directly to a
client-class name
3 append-to-tags Appends the user-class-id to the
selection-tags
