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