FTP service
File Transfer Protocol (FTP) is an application layer protocol based on the client/server model. It is used to
transfer files from one host to another over an IP network. FTP server uses TCP port 20 to transfer data and
TCP port 21 to transfer control commands.
APM monitors the FTP service status through simulating the behavior of the FTP client. This section
describes how to add and modify an FTP service application monitor, and helps view the monitor report.
Adding an FTP service application monitor
When you add application monitors for FTP, follow these guidelines:
•
Add FTP hosts to the IMC platform so APM can obtain and display network connections of the hosts
and their access devices in the application topology. For more information about adding hosts to
the IMC platform, see H3C IMC Base Platform Administrator Guide.
•
Obtain the FTP account of the user who has the file upload and download privileges, and the test
file to test the upload and download function of FTP. The test file can be at most 10 MB.
•
To view traffic statistics in the monitor report of the FTP service application, make sure at least one
probe is configured in APM. After an FTP application monitor is added, APM sends the IP address
and port of the monitored FTP service application to the probes for traffic collection.

1.
