to be detected. Users can then locate, solve, and log link problems by monitoring
the peer devices through the received ARP response packets.

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.
Layer 3 Connectivity
Detection Configuration
Example
Network requirements
■ The physical link between the local peer and the remote peer is correct. The
local peer port that is used to connect is Ethernet4/0/1.
■ The IP address of the lay 3 interface of the remote peer is 1.1.1.1.
Configuration procedure
# Enter system view.
<SW7750> system-view
[SW7750]
# Enter Ethernet interface view.
[SW7750] interface Ethernet 4/0/1
# Enable Layer 3 connectivity detection on Ethernet4/0/1 interface and specify the
IP address of the device (1.1.1.1) to be detected.
[SW7750-Ethernet4/0/1] uplink monitor ip 1.1.1.1
Configuring Queue
Traffic Monitoring
Upon enabling queue traffic monitoring on a switch, the switch monitors the
queue traffic and relieves blocks in the output queue of its interfaces.
The criterion used to distinguish a block is that the queue is full, and the traffic of
the corresponding interface is less than the specified threshold.
