4Motion 99 System Manual
To enable separation of the bearer IP and NMS IP domains, the following
(user-configurable) connectivity modes are defined:
Out-of-band connectivity mode: In this connectivity mode, the bearer and
external NMS IP domains are separated at the Ethernet interface. The DATA
port and bearer VLAN is used for the bearer IP domain, and the MGMT port
and external-management VLAN is used for external NMS connectivity.
In-band connectivity mode: In this connectivity mode, the VLAN is used to
differentiate between the bearer and external NMS IP domains on the DATA
port. The bearer VLAN is used for the bearer IP domain and the
external-management VLAN is used for the external NMS IP domain. The
MGMT port is assigned to the local-management VLAN in this connectivity
mode.
Unified connectivity mode: In this connectivity mode, the bearer IP domain
and external NMS IP domain are unified. That is, the same IP address and
VLAN are used to connect to the NMS server, AAA server, HA, and BS. (The
MGMT port is assigned to the local-management VLAN in this connectivity
mode.
For more information about the VLANs that are configured for 4Motion, refer the
section, “Configuring Physical and IP Interfaces” on page 101.
The following table lists the physical interface and VLAN configuration of bearer,
local-management, and external-management IP domains with respect to the
connectivity mode:
IMPORTANT
For all connectivity modes, the CSCD and MGMT ports operate in VLAN-transparent bridging mode
(untagged access mode). The assigned VLANs are used only for internal communication.
For all connectivity modes, the DATA port operates in VLAN-aware bridging mode (tagged-trung
mode).
IMPORTANT
In addition to the bearer IP domain, local-mangement IP domain, and external-management IP
domain, each NPU has an internal NMS IP domain. The internal NMS IP domain is used for
separating the IP domain for management traffic between the BS and NPU card.
In addition, the DATA port is assigned also to AU maintenance VLAN. AU maintenance IP domain is
used for separating the IP domain for maintenance (upload of maintenance reports) traffic between
the AUs’ service interfaces and external server.
