Alarm Configuration
7.6. The Invalid Access Lockout Alarm
The Invalid Access Lockout Alarm can provide notification when the VMR/NPS has
locked the Network port due to repeated, invalid attempts to access command mode.
Normally, the Invalid Access Lockout feature (discussed in Section 5.3.2) will lock the
network port whenever the VMR/NPS detects that a user-defined number of invalid
passwords have been entered at the Network Port. When the Invalid Access Lockout
Alarm is properly configured and enabled as described in this section, the VMR/NPS
can also provide notification via Email, Syslog Message or SNMP Trap.
Notes:
• In order for this alarm to function, Invalid Access Lockout parameters must
first be configured and enabled as described in Section 5.3.2.
• When an Invalid Access Lockout occurs, the VMR/NPS can still lock the
network port as described in Section 5.3.2, and can also send an email,
Syslog Message and/or SNMP trap if properly configured.
• If desired, the VMR/NPS can be configured to count Invalid Access attempts
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 VMR/NPS to provide Email alarm notification, communication
parameters must first be defined as described in Section 5.9.11.
• 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 5.9.2 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 5.9.7 and Section 12.
To configure the 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:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
Note: To cancel an alarm without unlocking the port, simply toggle the Trigger
Enable parameter Off and then back On again.
• ResendDelay: Determines how long the VMR/NPS will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification
was unsuccessful. (Default = 60 Minutes.)
