ฉันมีระบบ CentOS 5 ที่ใช้ DHCP สำหรับเครือข่ายย่อยหลายแห่ง ใน / var / log / ข้อความฉันเห็นข้อความคงที่ DHCPINFORM, DHCPACK และ DHCPREQUEST ฉันไม่เข้าใจว่าทำไมคำขอเหล่านี้ถึงเกิดขึ้นบ่อยกว่าการติดตั้งอื่น ๆ ข้อความจะระเบิดทุกสองสามวินาทีส่งผลให้ล็อกไฟล์ขนาดใหญ่มาก
อุปกรณ์จำนวนมากในที่นี้เป็นอุปกรณ์มือถือไร้สาย (ใช้สแต็ก Windows CE TCP) ฉันขอขอบคุณความเข้าใจอย่างถ่องแท้เกี่ยวกับการระงับข้อความคงที่

UPDATE
ฉันได้ลบip helper-address
รายการที่ไม่เกี่ยวข้องออกจากเราเตอร์ฝั่งเซิร์ฟเวอร์ DHCP บางรายการ ปริมาณการใช้งานส่วนใหญ่ลดลง แต่ฉันยังคงได้รับ DHCPINFORM จำนวนมาก DHCPACK ...
