A Console Terminal Server with a Ping Response Alarm Keeps an Eye on Your Network Equipment

Wouldn’t it be nice if your console terminal server could automatically notify you when a network device in a remote equipment rack decides to crash or hiccup? When a console terminal server includes a ping response alarm (or ping-no-answer alarm), the console server unit can regularly ping user selected IP addresses, and then provide prompt notification whenever a device at a target IP address fails to respond to a ping command.

A ping response alarm is an incredibly useful feature for network administrators who need to keep an eye on vital network elements located at remote equipment racks or far away data centers. When properly configured, the ping response alarm will ping vital network elements at user-defined time intervals and check for a response. If a target device fails to respond to a ping command, the console terminal server can then either immediately notify appropriate support personnel, send additional ping commands to double check for a response or continue to ping the target IP address until a user-defined threshold value of failed pings is reached, and then send an alarm.

Ideally, a ping response alarm feature on a console terminal server unit allows administrators to define target IP addresses that they wish to ping, the frequency at which target IP addresses will be pinged (ping interval,) the amount of time that will elapse before the next ping after receiving no response to an initial ping and the number of consecutive failed ping commands that will generate an alarm or user notification. In addition, a ping response alarm should also allow administrators to select several IP support personnel who will be notified when a pinged device fails to respond, and select an appropriate notification protocol for each notification recipient.

In some cases, the console terminal server ping response alarm can also send additional notification when one of the user-defined support personnel fails to respond the initial notification, or send secondary, “all clear” notification if the device at the target IP address begins responding to ping commands again. In order to allow the ping response alarm to fit the communication needs of a wide variety of different support personnel, the ping response alarm should support several popular communication protocols, such as email, text message, SNMP trap and SYSLOG message.

In most cases, network administrators are far too busy to personally watch every network device that they’re responsible for; continually waiting for a device to malfunction or hang. But a console terminal server with a ping response command can easily do the job; constantly pinging vital network elements at target IP addresses, checking for a response, and then promptly notifying IT support personnel when a device fails to respond.
