Description
The OOBM access switch will connect to the management interface of the managed network elements. The management interface of the managed network element must be directly connected to the OOBM network to ensure seperation. An OOBM interface does not forward transit traffic; thereby, providing complete separation of production and management traffic. Since all management traffic is immediately forwarded into the management network, it is not exposed to possible tampering. The separation also ensures that congestion or failures in the managed network do not affect the management of the device.

Check Text ( C-19237r1_chk )
Examine the connection from the OOBM access switch to the managed network elements. Verify which interface is being used at the managed network elements so that it can be determined if the interface is a true OOBM interface.

Fix Text (F-17735r1_fix)
Physically connected the OOBM access switch to the managed network element OOBM interface.
