Alarm Configuration
8.5. The Serial Port Invalid Access Lockout Alarm
The Serial Port Invalid Access Lockout Alarm can provide notification when the RPC has
locked the serial Console Port due to repeated, invalid attempts to access command
mode. Normally, the Invalid Access Lockout feature (discussed in Section 6.2.2) can
lock the serial Console Port whenever the unit detects that a user-defined threshold for
invalid access attempts at the Console Port is exceeded. When a serial port lockout
occurs, the unit can provide notification via Email, Syslog Message or SNMP Trap.

To configure the Serial Port Invalid Access Lockout Alarm, you must access the RPC
command mode using a password that permits Administrator Level commands. The
Invalid Access Lockout alarm configuration menu offers the following parameters:

alarmwillbesuppressed.(Default=On.)
