Protocol

Mode

Choose one of the following:

• Telnet: User names, passwords, and data are transmitted without

encryption.

• Secure SHell (SSH), version 1: User names, passwords, and data are

transmitted in encrypted form. There is little or no delay when you are

logging on.

• Secure SHell (SSH), version 2: User names, passwords, and data are

transmitted in encrypted form, but with somewhat more protection than

version 1 from attempts to intercept, forge, or alter data during data

transmission. There is a noticeable delay when you are logging on to

the Automatic Transfer Switch.

• Secure SHell (SSH), versions 1 and 2: Do not enable both versions of

SSH unless you require that both be activated at the same time.

(Security protocols use extensive processing power.)
