Why Do Most Large Networks Include an Out of Band Management Solution?

Monday, November 29th, 2010

Depending on who you ask, the term “out of band management” can have many different definitions. For some applications, “out of band management” refers to a maintenance network that supplements your main network in order to provide access to network elements when the main network is down. In other situations, “out of band management” might refer to the use of a dial-up connection to provide emergency access to command functions at console ports for troubleshooting and diagnostic purposes. One thing that these two definitions have in common, is the concept of console port command access via a secondary channel of communication as a means to support the main network.
