Determining Network Status

The DNS command displays the status of the network. If the network is running, the following message appears:

The terminal server determines network status by detecting traffic on the Ethernet link. The user sets the time interval for non-activity, which can range from 1 to 255 seconds. Two alarms indicate network status: if active the .NETUP alarm is issued, if inactive the .NETDOWN alarm is issued.

An attempt at a Telnet connection into the terminal server results in no response if the terminal server or network connection is down. A Sysop session through the AUX port is the only way to restart or communicate with the terminal server at this point.

NOTE: An Alarm/Event action routine must be created for these alarms. Otherwise the unit will receive the alarm but will not know what action to take.

To enter the time interval, type SNP 1 at the prompt. At the Network-Loss Alarm Delay Time, enter the time interval for non-activity on the network.
