Out of Band Management – An Alternative Avenue for Communication with Remote Devices

Tuesday, July 12th, 2011

One of the most difficult aspects of managing remote network devices is the challenge of communicating with remote network elements when normal network communication is either down or unavailable. When a vital network element at a remote equipment rack crashes and takes network communication down with it, sometimes the only means to address the problem is an expensive service call to the remote site in order to deal with the problem in person. In cases like this, an out of band management unit can provide network administrators with a convenient, reliable means to communicate with remote network elements regardless of whether communication via the main network is viable or not.

A Server Console Switch Provides Communication When No Network Cable is Available

Friday, May 20th, 2011

Often, the remote nature of a network equipment site makes it impossible to connect a network cable directly to the remote site. Although the remote network equipment site might include a LAN which allows communication between the devices at the site, outside users such as network administrators back at company headquarters, aren’t able to directly communicate with the devices at the site via network cable. In cases like this, sometimes the only way to establish communication with devices at the remote site is create a modem connection to a server console switch (http://www.wti.com/c-44-server-console-switch.aspx) at the remote site, and then use the server console switch’s outbound SSH or telnet capabilities to communicate via the LAN at the remote site.

A Console Access Server with Outbound SSH/Telnet Support Provides More Alternatives for Communication

Tuesday, April 26th, 2011

In out of band management applications that rely on a console access server (http://www.wti.com/c-51-console-access-servers.aspx) for communication with remote network devices, reverse/outbound SSH/Telnet can be an extremely useful feature. In addition to providing a means to communicate with other network devices, outbound SSH/Telnet is also extremely handy in cases where an equipment rack is not connected to your main network, and the only way to communicate with devices in the rack is via dial-up or satellite modem.

Outbound SSH and Telnet Allows a Terminal Switch to Go Where a Network Cable Can’t Go

Monday, April 11th, 2011

A full featured terminal switch unit (http://www.wti.com/c-56-terminal-switch.aspx) can often do a lot more than simply provide access to remote network elements when your main network is down. For example, if a terminal switch unit includes outbound SSH/Telnet capability, this allows administrators to create a dial-up connection with a remote terminal switch unit, and establish an SSH or Telnet connection with other devices that reside on the network at a remote site.

Outbound SSH – An Extremely Useful Capability for Server Console Switch Units

Friday, March 25th, 2011

A server console switch that supports outbound SSH connections allows network administrators to establish secure out of band connections with remote network elements, and provides an ideal tool for communicating with remote devices in situations where normal network communication is not available. This can prove particularly helpful, both in cases where a secondary/maintenance network is not available, and also in cases where the remote network equipment site is so far off the beaten path, that a direct network connection is not practical.

Out of Band Management – Access Command Functions on Remote Network Devices

Monday, February 7th, 2011

Out of band management provides a vital tool for network administrators by enabling secure, reliable communication with network devices even when the main network is down or not available. An intelligently planned out of band management solution helps to cut network maintenance costs by reducing costly service calls to remote equipment installations, and by providing administrators with a means to communicate with important devices without adding traffic to the main users network.
