Most network equipment has telnet enabled by default. Thesedays most devices can also support a protocol called SSH. I would suggest thatyou disable the insecure protocol telnet and enable a secure protocol calledSSH. Why? Telnet allows passwords to be seen in clear text and if someone issmart, they are able to capture your password.
If you ever have a security audit or this will be one of thefirst item they are looking for.
