since DHCP sends broadcast traffic to a vlan it has to be controlled, so by default you just have to assign an ip helper-address to manage dhcp requests out of your vlan. 2nd. check if your switch has dhcp relay service enable, for my particular model (C9300) i did delete and optio...
DHCP提供了一種機制,通過該機制,使用傳輸控制協定/網際網路協定(TCP/IP)的電腦可以通過網路自動獲取協定配置引數。DHCP是由Internet工程任務組(IETF)的動態主機配置工作組(Dynamic Host Configuration-Working Group,DHC-WG)開發的一種開放式標準。 DHCP基於客戶端 — 伺服器模式,其中DHCP客戶端(例如台式電腦)與DHCP...
