Chapter 2 Topology Management
Topology management enables you to construct and manage the topology structure of the network. You can keep track of the operation status of the entire network by browsing topological views of the network.
In topology management, you can upload topological data of network devices through topology auto discovery or by manually adding topology nodes. You can also add, delete, modify, and query topological devices. According to different management requirements of users, topology management provides such functions as non-hierarchically zooming, setting background, and auto layout. In this way, you can manage networks and devices easily.
Topology management can poll network devices and refresh their status regularly, thus making the network view display consistent with the actual network topology. In addition, topology management can monitor polling status and alarm status of network devices through color changes of the topological nodes.
Figure 1–1 shows the main window for topology management.
User Manual
HUAWEI iManager N2000 Fixed Network Integrated Management System
Chapter 1 Topology Management
2.1 Basic Concepts
The topology is a map of the managed telecommunications network in the NMS. It displays managed devices and links on the user interface using graphs and trees. Through the topology, users can perform such operations as configuration, alarm and performance.
The topological objects that can be managed include nodes, submaps and links.
2.1.1 Concept Description
I. Submap
In the NMS, a large network can be divided into several smaller networks by region or something else to facilitate network management. In the topology, these smaller networks are known as submaps.
II. Node
A node refers to a managed device that is mapped into the topology. For a single-frame device, a node represents the device. For a multiple-frame device, a node usually represents a frame in the device. Therefore, in the topology, a node and a device do not mean exactly the same.
III. Link
A link refers to a connection between devices that is mapped into the topology. In the topological view, the displaying of links follows these rules:
z If there is any connection relation between two objects in the same submap, a
link is drawn between the icons of the two objects. Double click the link, and you can query the detailed attributes, including the link name, link type and link status.
z If there is any connection relation between two objects in two submaps, a
shortcut icon is drawn at the lower right corner of each icon.
z If there is any connection relation between the lower submaps or nodes in two
submaps, a link is drawn between the two objects (two submaps). IV. View
In the NMS, different views can be used to display the topology, depending on the angle of observing network or the service range concerned. As examples, a physical view divides network topology structure based on regions or any other rules; an IP view divides a network into several smaller networks based on the IP network segment.
Each view corresponds to a device explorer and is concerned about different service points. Each device explorer includes several submaps, which show the network composition in the view. Each submap includes several nodes, as shown in Figure 1–2.
Figure 1–2 View V. Role
Switches in a cluster can play different roles based on the locations and functions. A cluster is a manageable network that comprises of multiple interconnected switches. It is assigned with a single IP address. All switches in the cluster must support Huawei Group Management Protocol V2 (HGMP V2). With the cluster management, the user can manage a group of switches without assigning an IP address to each member switch.
In the NMS, depending on different service angles, device nodes of the same type can be defined as different roles to implement different operation and configuration modes. For example, a Quidview device node, which is not defined in the physical view, may be defined as a command switch or member switch in the Virtual Local Area Network (VLAN) view.
The switches in a cluster can play the following roles.
z Command switch
The switch is assigned with a public network IP address and provides the main management interfaces for the overall cluster. A management command is first sent to the command switch for processing. If it finds that the command is destined to a certain member switch, it will redirect the command to the member switch.
User Manual
HUAWEI iManager N2000 Fixed Network Integrated Management System
Chapter 1 Topology Management
z Member switch
The switch is a member of a cluster, which is not assigned with a public network IP address in normal situations. It only receives the management commands redirected from the command switch.
z Candidate switch
The switch does not join any cluster, but has the cluster capability and can become a member of a cluster.
z Independent switch
The switch can be discovered in the process of gathering cluster topology information, but has no cluster capability and cannot become a cluster member.
VI. Filter
Filter is a special topological node. It can contain members. Currently, the filter often represents a multi-frame device. The multiple nodes under the filter represent the frames of the device.
VII. Polling status and alarm status
Polling status: The NMS queries the status and other configuration data of devices regularly, and displays the queried status information in the topological view.
The possible polling statuses include:
Normal, unknown, offline, insignificant, minor, major fault, critical, loopback, and test. Alarm status: The device reports trap information to the NMS. Then the trap information is displayed in the topological view.
The possible alarm statuses include: Critical, major, minor, and warning.
2.1.2 Icon Description
Corresponding to the concepts provided in the previous section, the topological view uses different icons to indicate submap, node, link, view objects and their statuses, and role.
For a node, a submap, or a link, the color of its icon shows its polling status. The status at the upper left corner of the icon shows its alarm status, lock status (locked or unlocked), and its role.
Below list the legends of the status icons. I. Polling status color legend
Normal Unknown Offline Insignificant Fault Minor Fault Major Fault Critical Fault Loopback Test II. Alarm icon
Critical Major Minor Warning III. Lock icon
indicates that the object is locked. IV. Shortcut icon
indicates a cross-submap link. V. Filter icon
indicates a filter.

2.3 Deploying Devices
Reasonable device deployment in the NMS can make the communication network more visual and improve the operability of the NMS.
Generally, deploying device should experience four phases: Preparations–>Creating a Submap–>Adding a Device to the NMS–>Creating a Link.
2.3.1 Preparations
Deploying a device is to deploy communication devices in the network in the topological view. Before deploying a device in the topological view, you should plan the topological submaps reasonably. If there are too many devices in a very large network, it is very difficult to locate and manage a device in one topological view. You can classify the topological view into topological submaps by:
z Geographical region, that is, the region where the communication device is
located.
z Device type, that is, the type of the communication device.
z IP network segment, that is, the IP address of the communication device. z Manager of the device.
Note:
z Up to 300 devices can be added to each submap. If there are too many devices in a submap, the
interface of the NMS will be much crowded and the devices will be overlapped. This will make locating devices inconvenient.
z Submaps should be arranged in 5 layers at most. If they are arranged in too many layers, it will cause
much trouble to operate on the NMS.
2.3.2 Adding a Submap
There is a very large and complex communication network. To ease the management and operation, you can divide it into several subnets based on the geographical region, type or IP network segment of devices. Each subnet is mapped to a submap in the topology.
Adding a submap helps you to manage the communication network easily. Each subnet can correspond to a submap.
