Hello @sim_157!

This is a normal phenomenon, you don't need to handle it. The NE router has a link detection mechanism. If the interface is up and receives the packets, then NE will start the link detection automatically. It sends the ICMP packets (the source and destination IP is NE itself, TTL is 2), the remote side receives this packet and will send it back to NE since the destination IP is the sender.

After NE has received the ICMP packet, it will compare the packet. If the data has been modified or it is time-out, NE will consider the link as unstable or problematic.

You can turn off this function with below command. Please note that the SAID node 2 is for physical interface, the SAID 3 is for trunk interface.

[HUAWEI]set said-node 2 slot 3 disable.
