Usage Guidelines

Usage Scenario

When detecting a fault, the EFM module notifies the OAM management module of the fault. The OAM management module searches the EFM fault relationship table based on the interface number and VLAN ID, and then clears the ARP entry that corresponds to the VLANIF interface.

Prerequisites

EFM has been enabled globally and on an interface using the efm enable command.

Example

# Enable GigabitEthernet0/0/1 in VLAN 10 to clear ARP entries.

<HUAWEI> system-view
[HUAWEI] efm enable
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] efm enable
[HUAWEI-GigabitEthernet0/0/1] efm trigger clear-arp vlan 10
