Login, Telnet, SSH and FTP Commands
exponential-backoff
Syntax [ no ] exponential-backoff
Context config>system>login-control
Description
This command enables the exponential-backoff of the login prompt. The exponential-backoff com-
mand is used to deter dictionary attacks, when a malicious user can gain access to the CLI by using a
script to try admin with any conceivable password.
The no form of the command disables exponential-backoff.
Default
no exponential-backoff
ftp
Syntax ftp
Context config>system>login-control

idle-timeout
Syntax idle-timeout { minutes | disable }
no idle-timeout
Context config>system>login-control
Description
This command configures the idle timeout for FTP, console, or Telnet sessions before the session is
terminated by the system.
By default, an idle FTP, console, SSH or Telnet session times out after 30 minutes of inactivity. This
timer can be set per session.
The no form of the command reverts to the default value.
Default
30 — Idle timeout set for 30 minutes.
Parameters
minutes — The idle timeout in minutes. Allowed values are 1 to 1440. 0 implies the sessions never
timeout.
Values
1 — 1440
disable — When the disable option is specified, a session will never timeout. To re-enable idle
timeout, enter the command without the disable option.
