DHCP Option 60 的理解

HCP 是RFC2131定义,DHCP 2132定义了dhcp option .

 Vendor class identifier

   This option is used by DHCP clients to optionally identify the vendor
   type and configuration of a DHCP client.  The information is a string
   of n octets, interpreted by servers.  Vendors may choose to define
   specific vendor class identifiers to convey particular configuration
   or other identification information about a client.  For example, the
   identifier may encode the client's hardware configuration.  Servers
   not equipped to interpret the class-specific information sent by a
   client MUST ignore it (although it may be reported). Servers that
   respond SHOULD only use option 43 to return the vendor-specific
   information to the client.
(这个选项作用于客户端可选地识别客户端厂商类型和配置,这个信息是n个8位编码,由dhcp服务端解析,厂商可能会为客户端选择定义特殊的厂商类标识符信息,以便表达特殊的配置或者其他关于客户端的信息。比如:这个标识符可能编码了客户端的硬件配置。客户端发送过来的服务器不能解析的类规范信息必须被忽略(尽管可能会有报告),服务器响应厂商规范信息到客户端应该仅仅通过Option 43来完成。
