Alarm Configuration
7.5. The Serial Port Invalid Access Lockout Alarm
The Serial Port Invalid Access Lockout Alarm can provide notification when the
TSM/RSM has locked the serial ports due to repeated, invalid attempts to access
command mode via serial port. Normally, the Invalid Access Lockout feature
(discussed in Section 5.3.2) can lock the serial ports whenever the unit detects that the
user-defined threshold for invalid access attempts has been exceeded. When the Serial
Port Invalid Access Lockout Alarm is properly configured and enabled, the unit can
also provide notification via Email, SYSLOG message or SNMP Trap when a serial port
lockout occurs.

To configure the Serial Port Invalid Access Lockout Alarm, you must access the TSM/
RSM command mode using a password that permits Administrator Level commands.
The Invalid Access Lockout alarm configuration menu offers the following parameters:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
