If the link
heartbeat function is enabled on an NE40E, the ICMP packets with both the source
and destination IP addresses as its own interface IP address are sent by
default. How do I disable this function?
Such packets have the following functions:
During network device operation, if a
packet is changed or packet loss occurs, the device must quickly determine the
fault scope and take the associated measures in time to restore services.
The NE40E and NE80E provide the link heartbeat function to support
loopback detection. Faults can be detected through heartbeat packets exchanged
between devices. During configuration of fault association, the device
automatically attempts to restore services. This improves network reliability
The link heartbeat loopback detection
function includes two types of fault detection: packet modification detection
and packet loss detection. In packet modification detection, the device checks
whether the content of the received heartbeat packets is the same as that of
the sent heartbeat packets. In packet loss detection, the device checks whether
the difference between the number of received heartbeat packets and the number
of sent heartbeat packets is within the scope. If the link heartbeat loopback detection
is enabled, packet modification detection is enabled by default. You can
configure to determine whether to implement fault association and whether to
enable packet loss detection.
Run the following commands to disable the function:
