Managing Multiple Terminal Switch Units via SNMP

When deploying a terminal switch product at a remote network equipment site, it usually pays to take an informed look at exactly what types of terminal switch features will prove useful for your specific application. Obviously, a terminal switch should provide out of band access capabilities for the other devices in the remote equipment rack, but there are also many other terminal switch features that can also come in very handy, depending on the nature of the type of network environment that you’re dealing with. If your network application involves communication with a number of different terminal switch units, spread across multiple remote equipment sites, then SNMP communication and MIB support can often be extremely helpful.

If your remote network equipment installations include terminal switch units with SNMP/MIB compatibilities this enables network administrators to issue similar configuration and operation commands to multiple terminal switch units. This streamlines the process of making across-the-board configuration changes to a range of terminal switch units, simplifies user account management, provides broader abilities to set and change environmental and alarm functions and also speeds the process of retrieving buffered data from terminal switch serial ports. Operation via SNMP essentially allows administrators to reconfigure and manage multiple terminal switch units from a single interface, and saves time that would otherwise be spent accessing each terminal switch individually.

SNMP support can also be useful in applications that involve the collection of error and status messages generated by attached network devices. In this case, SNMP compatibility enables administrators to easily configure terminal switch units to automatically forward buffered data to support techs and other personnel via SNMP trap as each data item is received. In other cases, SNMP traps are used to notify the appropriate personnel when terminal switch serial port buffers fill to a user-specified threshold level, in order to allow retrieval of buffered data before it is overwritten.

If the terminal switch unit also supports the ability to define event alarms and environmental alarms, SNMP traps can be used to transmit alarm notification when rack temperature conditions, power supply instability, invalid password attempts and other significant events are detected. Ideally, the terminal switch should support the ability to send SNMP traps to multiple different response personnel, in the event that the primary responder is not available.

A terminal switch unit with SNMP support provides network support personnel with a uniform standard for communication with remote network devices and ensures compatibility with a wider variety of network devices and services. If your out of band management application requires communication with multiple remote network equipment racks, a terminal switch unit with SNMP/MIB support can provide a comprehensive solution for centralized management and operation of multiple terminal switch units, without the need to individually address each terminal switch in your network infrastructure.
