ARP攻击就是通过伪造IP地址和MAC地址实现ARP欺骗,能够在网络中产生大量的ARP通信量使网络阻塞,攻击者只要持续不断的发出伪造的ARP响应包就能更改目标主机ARP缓存中的IP-MAC条目,造成网络中断或中间人攻击。ARP攻击主要是存在于局域网网络中,局域网中若有一个人感染ARP木马,则感染该ARP木马的系统将会试图通过“ARP欺骗...
5. Run the arp-miss speed-limit [ ip-address ]source-ip maximum maximum command to re-set the maximum value of timestamp suppression of ARP Miss messages. This value must be greater than that displayed in Step 4; otherwise, the trap cannot be cleared, but this value must be less than...
Run the arp speed-limit source-ip [ ip-address ] maximum maximum command to reconfigure the maximum value for timestamp suppression of ARP packets. This value must be greater than the value obtained in Step 2 but must be less than 16384; otherwise, the trap cannot be cleared. Check whether...
为避免这种大量目标IP不能解析的IP报文攻击所带来的危害,设备提供了ARP源抑制功能,命令行为arpsource-suppression enable(默认此功能关闭),当开启该功能后,如果网络中某主机向设备某端口连续发送目标IP地址不能解析的IP报文,当每5秒内对该目的IP 解析的ARP 的流量超过设置的阈值,系统就会丢弃由此端口进入的与发送者IP...
Defines different restriction levels for announcing the local source IP address from IP packets in ARP requests that send on an interface: 0: Use any local address configured on any interface. 1: Avoid local addresses that are not in the target subnet for this interface. You can use this mod...

After all hosts receive the ARP Request message, they will check whether its destination protocol address field matches their own IP address. If it does not match, the host will not respond to the ARP Request message. If they match, the host will record the source MAC address and source IP...
