Issue Description

Device model: NE40E

Software version: V8R7C00SPC100

Symptom: How to disable listening of TCP port 22?


The customer feedback shows that the SSH service has been disabled. Then, why devices can still be connected by means of SSH?


The device is still listening to TCP port 22.


TCP port 22 involves multiple services, including the SFTP server, STelnet server, SCP server, and SNETCONF server.

After all these services are disabled, the device will not listen to TCP port 22 any more.
