IP address conflict detection between a switch and other devices
A CE switch can detect whether its IP address conflicts with the IP address of another device without any configuration. If an IP address conflict of this type occurs, the switch records the ARP/4/ARP_DUPLICATE_IPADDR log and reports the ARP_1.3.6.1.4.1.2011.5.25.165.2.2.2.1 hwArpsGatewayConflict alarm.
IP address conflict detection between downstream devices connected to a switch
After the arp ip-conflict-detect enable command is run in the system view, a CE switch can detect whether IP addresses of downstream devices connected to the switch conflict. If an IP address conflict of this type occurs, the switch records the ARP/4/ARP_IP_CONFLICT_DETECT log and reports the ARP_1.3.6.1.4.1.2011.5.25.123.2.6 hwEthernetARPIPConflictEvent alarm.
