A Good Serial Switch Can Do More than Provide Out of Band Access

Wednesday, August 3rd, 2011

When most network administrators hear the phrase, “serial switch,” they will generally think of an out of band management unit that provides alternative access to vital network elements when communication via the main network is unavailable. But in addition to providing a channel for secure, reliable out of band management, often, a full featured serial switch product can also serve double duty in helping with the task of collecting error messages and other data collected from attached network devices.


Data Buffering – Yet Another Useful Feature Provided by a Serial Switch

Thursday, April 7th, 2011

In most applications, a serial switch is used to provide secure, out of band access to command functions on remote network elements, allowing diagnosis and troubleshooting of problems at remote network sites when the main network is not available. In addition to this crucial out of band management function, in some applications serial switches are also used to collect data and error messages that remote network elements send out via console port. In cases where the serial switch is used to buffer console port data, a buffer threshold alarm can prove to be an extremely helpful feature for administrators who need to collect this buffered data for use in analytical and diagnostic programs.


How Serial Console Server Units Can Help to Collect Data Generated by Connected Devices

In addition to providing out of band access to network elements, a serial console server ( can also be used to collect error messages and other data from connected devices. When an error message or status message is sent out via the console port on a connected device, an intelligently designed serial console server can store the data at a serial port buffer for later retrieval by administrators and others who need that data for diagnostic purposes. If the serial console server includes a buffer threshold alarm, it can also notify users when new data is received by the buffer or when the buffer is nearly full.


Create Direct Connections to Console Server Serial Ports

In most network applications, a console server ( is used to provide out of band management access to console port command functions on remote network devices. But that said, there are also many other things that a console server can be used for. For example, in some applications, a console server is used in conjunction with a command script to allow a program to control port switching and connection functions, or to collect buffered data from connected devices.


A Console Terminal Server with SNMP Support Capabilities Can Simplify Out of Band Management

Thursday, February 3rd, 2011

A console terminal server with SNMP compatibility can provide network administrators with a number of extremely valuable tools that simplify the process of managing important network elements located at remote, off-site network equipment sites. SNMP compatibility enables administrators to use MIB objects to change configuration parameters, check unit status and add or remove user accounts, and in addition, also provides the ability to forward data collected from attached devices to the appropriate network support personnel.
