Alarm Configuration
8.6. The Serial Port Invalid Access Lockout Alarm
The Serial Port Invalid Access Lockout Alarm can provide notification when the VMR/
NPS has locked the serial SetUp 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 SetUp Port whenever the unit detects that a user-
defined threshold for invalid access attempts at the SetUp 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
SetUp Port. To apply the Invalid Access Lockout feature to the Network Port,
please refer to Section 6.2.2.
• 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 6.2.2.
• If desired, the VMR/NPS can be configured to count Invalid Access attempts
at the serial SetUp 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 6.2.2, set the Lockout Attempts and Lockout Duration as you would
normally, and then set the "Lockout Enable" parameter to "Off."
• In order for the VMR/NPS to provide Email alarm notification, communication
parameters must first be defined as described in Section 6.8.10.
• In order for the VMR/NPS to provide Syslog Message notification, Syslog
parameters must first be defined and Syslog Messages must be enabled as
described in Section 6.8 and Section 11.
• In order for the VMR/NPS 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 6.8.6 and Section 12.
To configure the Serial Port Invalid Access Lockout Alarm, you must access the VMR/
NPS 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:
• 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 VMR/NPS alarms. For example,
if the Invalid Access Lockout Alarm's Trigger Enable parameter is set to "On
(Copy to All Triggers), then other VMR/NPS alarms will also be enabled.
