SubscriberDhcpClass
A string-value specifying the name of the class matching the DHCP DISCOVER message received from the subscriber. The semantics of the string-value are the same those specified by the SnmpAdminString textual convention defined by the SNMP-FRAMEWORK-MIB (RFC-3411). The null string is not a valid value. However, it serves as a convenient value when an instance of an object using this textual convention is not valid.
