Description
The OOBM access switch will connect to the management interface of the managed network elements. The management interface can be a true OOBM interface or a standard interface functioning as the management interface. In either case, the management interface of the managed network element will be directly connected to the OOBM network. If the device does not have an OOBM port, the interface functioning as the management interface must be configured so that management traffic does not leak into the managed network and that production traffic does not leak into the management network.

Check Text ( C-19241r1_chk )
Review the managed switch configuration and verify that the access port connected to the OOBM access switch has been assigned to the management VLAN.

Fix Text (F-17739r1_fix)
If the management interface is an access switchport, assign it to a separate management VLAN while the remainder of the access switchports can be assigned to user VLANs belonging to the managed network. This provides some level of separation between the management network and the managed network.
