| System Management Commands
Line
– 119 –
password-thresh This command sets the password intrusion threshold which limits the number of
failed logon attempts. Use the no form to remove the threshold value.
Syntax
password-thresh [threshold]
no password-thresh
threshold - The number of allowed password attempts. (Range: 1-120; 0: no
threshold)
Default Setting
The default value is three attempts.
Command Mode
Line Configuration
Command Usage
When the logon attempt threshold is reached, the system interface becomes silent
for a specified amount of time before allowing the next logon attempt. (Use the
silent-time command to set this interval.) When this threshold is reached for Telnet,
the Telnet logon interface shuts down.
Example
To set the password threshold to five attempts, enter this command:
Console(config-line)#password-thresh 5
Console(config-line)#
Related Commands
silent-time (119)
silent-time This command sets the amount of time the management console is inaccessible
after the number of unsuccessful logon attempts exceeds the threshold set by the
password-thresh command. Use the no form to remove the silent time value.
Syntax
silent-time [seconds]
no silent-time
seconds - The number of seconds to disable console response.
(Range: 0-65535; where 0 means disabled)
Default Setting
Disabled
