DHCP Snooping เป็นการป้องกันไม่ให้มี DHCP Server แปลกปลอมแจก IP เข้ามาในระบบครับ
DHCP Server แปลกปลอม เช่นอะไรบ้าง?
พวก Wireless Router เลยครับ ที่เป็น Router มี Port WAN/ Port LAN 4 Port และกระจาย WIFI ได้ด้วย อุปกรณ์พวกนี้โดย Default จะมี DHCP Server ในตัว และ Enable ให้แจก IP ไว้
มีลูกค้าหลายๆท่านนำพวก Wireless Router มาต่อเข้าระบบ ตั้งใจไว้ว่าจะให้ปล่อย WIFI แต่อาจจะลืมปิด DHCP Server ไว้ ทำให้แจก IP สวนเข้ามา เครื่องไหนแจ๊คพอตได้ IP จาก Wireless Router ก็จะมองว่า Wireless Router นั้นๆเป็นตัวออก Internet แต่จริงๆแล้วมันออกไม่ได้ เลยทำให้ เครื่อง Client ต่างๆที่ได้ IP จาก Wireless Router พวกนี้ ออก Internet ไม่ได้ตามไปด้วย
ใน Reyee Managed Switch รุ่น NBS3000 Series และ NBS5000 Series รองรับ Mode DHCP Snooping จะเป็นการระบุว่า Port ไหนที่ยอมให้ DHCP Server แจก IP เข้ามาในระบบ นอกนั้นไม่ยอม (ขอใช้คำง่ายๆนะครับ)
