Network Out-of-Band Management (OOBM) for the 6600 Switch

Concepts

ConceptsManagement communications with a managed switch can be:■in band—through the networked data ports of the switch

■out of band—through a dedicated management port (or ports) separate from the data ports

Out-of-band ports have typically been serial console ports using DB-9 or specially wired 8-pin modular (RJ-style) connectors. Some recent HP ProCurve switches have added networked out-of-band management ports. The illustration below shows management connections for a typical switch.

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 in- band 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
