执行命令arp status-detect ip-address,使能ARP与接口状态联动功能。 ARP探测报文的目的IP地址需要与本端接口的IP地址处于同一网段,被探测端的设备不需要进行任何配置。 (可选)执行命令arp status-detect mode loose,配置接口以松散模式发送ARP探测报文。 在严格模式下:只要本端接口的物理状态Up,就会主动发送ARP探测报...
1. Enable the ARP status-detect function and assign an IP address to an interface. Then assign a new IP address to the interface. If you find that the ARP status-detect function is disabled, possible causes are as follows: (1) The IP address newly assigned to the interface and the IP...
hwArpEntryExpireDetectMode Integer {broadcast(1), unicast(2)} read-write ARP老化探测模式。 当为单播探测时,老化前系统将以单播的方式发送ARP探测报文。 当为广播探测时,老化前系统将以广播的方式发送ARP探测报文。默认为广播探测模式。 实现与MIB文件定义一致。 1.3.6.1.4.1.2011.5.25.123.1.16.1.3 h...
This feature enables the device to detect and record user IP address conflicts. The device determines that a conflict occurs if an incoming ARP packet has the same sender IP address as an existing ARP entry but a different sender MAC address. The device gene...

After the aging time of a dynamic ARP entry expires, the device sends an aging probe packet (ARP Request packet) to detect whether the peer device is present. If the device receives an ARP Reply packet, it updates this dynamic ARP entry. If the device does not receive an ARP Reply ...
ARP poisoning (also known as ARP spoofing) is a cyber attack carried out through malicious ARP messages An ARP attack is difficult to detect, and once it's in place, the impact is impossible to ignore. A hacker that successfully implements either ARP spoofing or ARP poisoning could gain cont...
