This string contains attribute-value pairs that are added to the
environment dictionary whenever this client-class is associated
with an incoming DHCP request. You can use these attribute-value
pairs to configure extensions or expressions without having to
re-write the executable code in the extension or expression. The
string must have the format:
"attribute1=value1,attribute2=value2, ... ,attributen=valuen"
client-lookup-id expr
Specifies the key value used to lookup the specified client in the
client database, using an expression that evaluates to a string
or a blob that is a valid string. The lookup can be local or through
LDAP.
default-vpn nameref(VPN)
Determines the VPN to which a client is assigned if the client does
not supply a VPN-ID (or vrf-name) value.
domain-name string
Sets the domain name, which must be a zone, for performing DNS
updates. Places the client's A record in this DNS domain.
This feature is maintained for compatibility with prior versions.
Additional options to specify the forward zone are provided on
the client-class's policy (or embedded policy) and its
referenced DNSUpdateConfig objects.
embedded-policy obj(Policy)
Specifies the embedded policy object for this client-class.
host-name string
Specifies the hostname for clients in this client-class.
Network Registrar uses this form of hostname value to signal the
following special handling:
@host-name-option
Causes the server to use whatever hostname option the
client sent. This is the default behavior if there is no
entry for host-name in either the client or client-class.
@no-host-name-option
Causes the server to drop the hostname option that the
client sent, and not replace it. If you have disabled
DNS name synthesis, then the client will have no name
placed into DNS.
@use-macaddress
Causes the server to synthesize a host-name for the
client that is derived from its MAC address, and is thus
unique. This token is used to ensure that a client has a
valid name in DNS.
This feature is maintained for compatibility with prior versions.
Additional options for host-name synthesis are provided on the
DNSUpdateConfig object referenced by the policy hierarchy.
