4.3.1 Managing the IP Connectivity Mode
The following are the various types of traffic originating or terminating from/to the
NPU:
 Subscriber data flows
 ASN/CSN control messages
 Network Management System (NMS) traffic (external management traffic)
 Local management traffic
 Internal management traffic
4Motion has defined separate IP domains for each traffic type:
 Bearer IP domain: Enables connectivity between ASN-GW (NPU), Base Station
(BS), AAA server and the Home Agent (HA) for managing transport for
subscriber data and the ASN/CSN control traffic.
 NMS IP domain (external management IP domain): Defines the connectivity
between NMS agent of the NPU and external NMS server.
 Local management IP domain: Defines the connectivity between the NMS
agent of NPU and IP-based local craft terminal.
 Internal management IP domain: Enables connectivity between the NPU NMS
agent and management agents for the AU cards.
 Subscriber IP domain: NPU supports subscriber IP domain through multiple
VLAN service interfaces.
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.
