    scope selection tags. The DHCP server looks up these properties
    to determine how it should process a host request for an IP
    address.
    
    If you have common client attributes to configure, such as
    selection criteria, use the client-class so that multiple client
    configurations can reference the attributes.
          
    You can specify the client by using the MAC address or some
    other unique client identifier related to the client-lookup-id
    that is specified in the client's associated client-class.
    A sample Ethernet MAC address might be 1,6,00:a0:24:2e:9c:20
    client name create [attribute=value...]
    client default create [attribute=value...]
       Creates the client identifier as a MAC address or the word
       default (and optionally defines its attributes). The default
       client configuration applies to all clients that do not have
       an explicit configuration. If an entry for the client already
       exists, the command overwrites it.
       If using a MAC address, it should be in the form hardware,
       length, address (without spaces and including the commas):
          hardware
          Usually 1 (Ethernet) or 6 (Token Ring), but can be any number
 
  from 1 through 255.
          length
          Octets in the MAC address (usually 6, but can be any number
 
  from 1 through 16).
          address
          MAC address itself, with octets separated by colons, and each
 
  octet having a two-character hex value from 00 through FF
 
  (not case-sensitive).

  Attributes
 
 
action 
(exclude=1, deprecated-one-shot=2, deprecated-use-release-grace-period=3, none=32)
 
Describes the action the DHCP server takes for this client.
    1  exclude - causes the server to ignore all
       communication from this client.
    2  deprecated-one-shot - now deprecated.
    3  deprecated-use-release-grace-period - now deprecated.
    32 none
If you specify the exclude action in the default client
entry, then any client not specifically registered through
the client command cannot communicate with the server.
Note: The deprecated flags (2,3) are now available through
the policy command attributes inhibit-all-renews and
release-grace-period.
 
add-to-environment-dictionary 
 
Lists 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 rewrite
the executable code in the extension or expression.
The string must have the format:
"attribute1=value1,attribute2=value2, ... ,attributen=valuen"
