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。
