Alarm Configuration
7.5. 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 5.3.2) 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.
Notes:
• Note that Serial Port Invalid Access Lockout Alarm is only intended to provide
notification when the Invalid Access Lockout feature has locked the serial
Console Port. To apply the Invalid Access Lockout feature to SSH, Telnet or
Web access, please refer to Section 5.3.2.
• In order for this alarm to function, Invalid Access Lockout parameters
for the serial port must first be configured and enabled as described in
Section 5.3.2.
• If desired, the RPC can be configured to count Invalid Access attempts at
the serial Console port, and provide notification when the counter exceeds
a user defined trigger level, without actually locking the port in question. To
do this, enable the Invalid Access Lockout Alarm as described here, but
when you configure Invalid Access Lockout parameters as described in
Section 5.3.2, set the Lockout Attempts and Lockout Duration as you would
normally, and then set the "Lockout Enable" parameter to "Off."
• In order for the RPC to provide Email alarm notification, communication
parameters must first be defined as described in Section 5.9.11.
• In order for the RPC to provide Syslog Message notification, Syslog
parameters must first be defined and Syslog Messages must be enabled as
described in Section 5.9.2 and Section 11.
• In order for the RPC to provide SNMP Trap notification when this alarm is
triggered, SNMP parameters must first be defined, and SNMP Traps must be
enabled as described in Section 5.9.7 and Section 12.
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:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
Note:
• When an alarm is generated, to cancel an alarm without correcting the
condition that caused the alarm, simply toggle the Trigger Enable parameter
Off and then back On again.
• The Trigger Enable, Notify on Clear, Email Message and Address 1, 2 and 3
Parameters all include "Copy to All Triggers" options that allow you to enable/
disable the corresponding parameter for all RPC alarms. For example, if the
Invalid Access Lockout Alarm's Trigger Enable parameter is set to "On (Copy
to All Triggers), then other RPC alarms will also be enabled.
