4.4 Configuring Layer 3 Connectivity Detection

4.4.1 Introduction to layer 3 connectivity detection

The function that detects layer 3 connectivity is implemented as follows. Local devices
send ARP request packets continuously to the IP addresses of the devices to be
detected. Users can then locate, solve, and log link problems by monitoring the peer
devices through the received ARP response packets.
Note:
This function requires no Layer 3 device existing between the local peer and the remote
peer.

4.4.2 Layer 3 Connectivity Detection Configuration Task

Note:
Before performing this configuration, make sure the physical link between the local
peer and the remote peer is correct, and the related VLAN interfaces are assigned with
correct IP addresses.
Follow these steps to configure Layer 3 connectivity detection:
