The dhcp option82 format command configures the format of the Option 82 field in DHCP messages sent from STAs. The undo dhcp option82 format command restores the default format of the Option 82 field in DHCP messages sent from STAs. By default, the format of the Option 82 field in DHCP mes...
这个选项被称为:DHCP relay agent information option(中继代理信息选项),选项号为82,故又称为option 82,相关标准文档为RFC3046。 Option 82是对DHCP选项的扩展应用。选项82只是一种应用扩展,是否携带选项82并不会影响DHCP原有的应用。另外还要看DHCP服务器是否支持选项82。不支持选项82的DHCP服务器接收到插入了选项8...
82中常用的sub-option1、sub-option2和sub-option5。 sub-option1 sub-option1是option82的一个子选项,为代理电路id(即circuitid)子项。子选项通常在dh cp中继设备上配置,定义了在传输报文的时候要携带dhcp客户端所连接交换机端口的vlan-id及二层端
