A Serial Console Switch with Alarm Notification via SNMP Trap

A serial console switch performs many different duties in a network application; it allows out of band access to network devices when your main network is down, it provides a backdoor to configuration and diagnosis functions without interfering with regular network communication, and it can also monitor network devices for potentially harmful environmental conditions and suspicious network events. Alarm and monitoring functions are an extremely useful capability, but only when the console switch includes a means to effectively notify network administrators when a problem is detected.

With that in mind, WTI serial console servers support several different notification methods that can be used when an alarm is triggered; network administrators can be notified via text message, email, SYSLOG message, or via SNMP trap. While email is probably the most common form of alarm notification, SNMP Traps remain a popular solution for network administrators who need prompt notification when critical network events are detected.

In order to allow network administrators to keep constant track of conditions at remote network installation sites, WTI console switches include an impressive array of environmental and event alarm. All of these alarms are highly user-configurable to allow adaptation to a wide variety of different monitoring applications, and all of these alarms also include the ability to provide notification via SNMP trap. When user-defined critical conditions are detected, WTI console switches can provide immediate notification via SNMP trap, email, text message or SYSLOG message.

With a WTI console switch, network administrators can constantly monitor network devices, watching for critical events that might require their attention. This means that when any of the alarms listed below are triggered, a WTI console server can send an easily read, SNMP trap to the appropriate personnel in order to allow them to attend to the problem as quickly as possible:

  • Over Temperature Alarm – Provides prompt notification when rack temperature rise above, or fall below, user-defined target temperatures.
  • Lost Communication Alarm – Notifies system administrators when communication with the network device is interrupted or discontinued.
  • Ping-No-Answer Alarm – Pings user-defined target devices at regular intervals, and then provides notification when the device fails to respond.
  • Invalid Access Lockout Alarm – Counts invalid password attempts, and then immediately notifies the proper personnel when attempts rise above a user-defined threshold.
  • Power Cycle Alarm – Notifies network administrators when power to the console switch is cycled off and on.
  • Buffer Full Alarm – Monitors console switch port buffers and provides prompt notification when buffer memory use rises to a user-defined level.

Many different console switches include features that can be used to monitor connected network devices; that’s very useful, but it’s even more important that the console switch can notify you when suspect conditions are detected. WTI console switches provide quick, flexible notification features to keep network administrators constantly informed via SNMP trap, email, text message or SYSLOG message.
