Out-of-Band Management

The backplane data bus supports Out-of-Band Management and In-Band Management configurations.

Out-of-Band Management is available by directly connecting the Network Management Station (NMS) to the UTP port on the front of the NMM. This isolates the management traffic from the rest of the traffic in the chassis.

In-Band Management

In-Band Management is supported by using the chassis backplane to provide connection between the NMM and an adjacent module. The adjacent module provides access between the NMM and the NMS via the backplane data bus. In order to provide a secure management connection, a management VLAN must be configured (see section 3.4.3 on Management VLAN).
