Overview of Topology View


Overview of Topology View

Topology View in D-View 7 provides the feature to visualize network topology of devices. In topology view, users can monitor status of device in real time, including:

  • Link status between devices (i.e. On / Off)
  • Link capacity and its connected ports
  • Alert events on devices (i.e. Info, Warning, and Critical)

Topology has various display methods, an user can:

  • Select the format to be a Tree or Star type
  • Choose whether to include the IP address and device name
  • Zoom in & zoom out the topology


Default Topology

The default topology is generated by D-View 7's probe(s) through information collected from devices. Each probe is represented by a cloud icon in the topology which indicates a subnet (IP range). Once you click on the cloud, you can then see how devices are connected within the subnet.

Each probe may have different topologies, depending on the number of IP range / subnet being configured in the probe settings and how devices are connected.  D-View 7's default topology is automatically updated using the information collected and can not be changed manually.


Customized Topology

As more and more devices being managed by D-View 7, the default topology could become very complicated. An user may want to focus on monitoring certain part of the network only.


Examples for Customized Topology

1. Topology on devices connected within n hops from the core switch

For example, the topology may be too complicated and you like to focus on the network that are connected within 2 hops from the core switch (n=2).  In this case, a customized topology can be created to meet this demand. Below is the topology of this situation.


2. Logical connection on devices

It is also possible that an user may want to view the logical or virtual connection between devices.  For example, devices can be communicated via VPN technology where devices are not directly connected but a manual link between the devices can be placed in the topology to show the virtual connection.
