Summary

A TELNET Handshake can be used to verify the functionality of FTP, POP3, SMTP, and

WWW subsystems for SLA purposes.

Technical Background

TCP Connections are generally giving a higher priority level within routers than ICMP packets.

For this reason, a Customer may choose to use TELNET handshake (TCP Connection)

rather than a simple PING (ICMP connection) for SLA testing.

A TELNET handshake can be used to for SLA reporting on the availability of

subsystems such as FTP, POP3, SMTP, and WWW.

For POP3 SLA testing, Screen G11A can be used to Telnet to TCP port 110, and

perform the ‘handshake’ seen on screen G11D.

For FTP, connect to port 21, and use the following handshake:

For SMTP, connect to port 25, and use the following handshake:

For WWW, connect to port 80, and use the following handshake:
