Alarm Configuration
7.7. The Invalid Access Lockout Alarm
The Invalid Access Lockout Alarm is intended to provide notification when the MPC
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 MPC 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 MPC 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 MPC 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 MPC 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 MPC to provide Email alarm notification, communication
parameters must first be defined as described in Section 5.9.11.
• In order for the MPC 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 MPC 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.
