G-3 Network Out-of-Band Management (OOBM) Concepts 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 in- band managem ent traffic. That separa tion means that out- of-band manage- ment can contin ue [...]

G-5 Network Out-of-Band Management (OOBM) Concepts Example In a typical data center installation, blade switches in a C-class enclosure connect servers to the data network, while the management port of the OA module in the C-class encl osure conn ects the switches to a physically and logically separate management network. This allows network admini[...]

G-11 Network Out-of-Band Management (OOBM) Tasks OOBM Show Commands The show commands for OOBM are similar to the analogous commands for the data plane. Note that you must always include the oobm parameter to see the informati on for the OOBM inte rfac e, regardless of the context. For instance, even from the OOBM context the show ip command displa[...]
