A Serial Console Server that Supports Data Buffering

Thursday, June 30th, 2011

In many remote network equipment rack applications, the serial console server is mainly used to provide out of band management access to console port command functions on vital network elements. Although out of band management capabilities are absolutely vital for the efficient management of remote network devices, a serial console server can also be called on to perform other tasks that can be equally helpful to network administrators. For example, a serial console server that includes buffer mode ports can also be used to collect error messages and other data from connected network elements.

Console Access Server units can perform a number of valuable tasks in a remote network equipment installation. In addition to providing secure, reliable out of band access to console port command functions when the main network is not available, console access servers can also be used to collect error messages and other data, generated by connected network devices.

The Buffer Threshold Alarm – A Handy Feature for Serial Switches Used in Data Collection Applications

Thursday, May 5th, 2011

It’s not uncommon to find serial switch units used for other purposes, besides out of band management applications. For example, serial switch units are often used to collect error messages, status reports and other data that network devices generate and then send out via console port. In data collection applications like this, it’s helpful if the serial switch includes a buffer threshold alarm, to notify network administrators when data has accumulated in a serial port buffer.

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

Wednesday, March 23rd, 2011

In addition to providing out of band access to network elements, a serial console server (http://www.wti.com/c-48-serial-console-servers.aspx) 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.

Can Your Console Server Tell You When Error Messages are Received?

Wednesday, July 14th, 2010

When a problem arises with a server or router or switch, many network devices can be configured to generate error messages and then send those messages out via console port. Sometimes, error messages can provide network administrators with incredibly useful information regarding system status and operating conditions, often allowing the administrator to address a problem before it’s even noticeable to network users … as long as the administrator knows that an error message has been generated in the first place.
