DHCP class with dhcp-client-identifier?

Hi,

I’m using linux DHCPD to assign specified IP range to client with client id(user input manually) like: group1xx

class "group100" {
match if substring (option dhcp-client-identifier, 1, 5) = "group" ;
}
pool { range 10.1.1.100 10.1.1.200;allow members of "group100";}

Is this possible accomplished with ROS? Thanks in advance.
