-    >In substring \(option dhcp6.vendor-class, 6, 10\), the start position of the substring is 6, because the substring contains four bytes of <Enterprise-ID number\> and two bytes of <string length\>. The end position of the substring is 6+<vendor class string length\>. In this example, the vendor class string is HWHW, and the length of the string is 4. Therefore, the end position of the substring is 6 + 4 = 10. You can specify <vendor class string\> and <vendor class string length\> as required.
