Configuring ARP Detection on Huawei ME60

Address Resolution Protocol ME60-X3 (ARP)  probe enables faster protection switching by detecting status of end-to-end links. ARP detection can be configured for a network scenario in which a link protection group is configured for the upstream Ethernet ports on the access device, and there are other types of devices deployed, such as switches and transmission devices, between the access device and the aggregation devices.

Prerequisites

The access device provides upstream ports through the upstream boards. ARP detection is not supported if the access device provides upstream ports through the control board.

//Configure the VLAN and Layer 3 interface IP address used for ARP detection of the local device.

huawei(config)#vlan 20 smart

huawei(config)#port vlan 20 0/19 0

huawei(config)#interface vlanif 20

huawei(config-if-vlanif20)#ip address 1.1.1.2 24

huawei(config-if-vlanif20)#ip address 2.2.2.2 24 sub

huawei(config-if-vlanif20)#quit

//Configure ARP detection for the working port.

huawei(config)#arp-detect arp_test1 bind peer-ip 1.1.1.1 vlan 20 port 0/19/0

huawei(config-arp-detect-arp_test1)# detect-multiplier 3

huawei(config-arp-detect-arp_test1)# min-tx-interval 2

huawei(config-arp-detect-arp_test1)#detect enable

huawei(config-arp-detect-arp_test1)#quit

//Configure ARP detection for the protection port.

huawei(config)#arp-detect arp_test2 bind peer-ip 2.2.2.1 vlan 20 port 0/19/1

huawei(config-arp-detect-arp_test2)#detect-multiplier 3

huawei(config-arp-detect-arp_test2)#min-tx-interval 2

huawei(config-arp-detect-arp_test2)#detect enable

huawei(config-arp-detect-arp_test2)#quit

//Query configurations of the working port.

huawei(config)#display arp-detect arp_test1
