Network Out-of-Band Management (OOBM) Concepts management port (networked, out of band) Figure D-1. C-class enclosure OA Management port Out-of-band management (OOBM) operates on a "management plane" that is separate from the "data plane" used by data traffic on the switch and by inband management traffic. That separation means that out-of-band manage­ ment can continue to function even during periods of traffic congestion, equipment malfunction, or attacks on the network. In addition, it can provide improved switch security: a properly configured switch can limit management access to the management port only, preventing malicious attempts to gain access via the data ports. Network OOBM typically occurs on a management network that connects multiple switches. It has the added advantage that it can be done from a central location and does not require an individual physical cable from the manage­ ment station to each switch's console port. The table below summarizes the switch management ports. Table A-1.
