Understanding the Network Topology in Connectivity Services Director

 

Junos Space Connectivity Services Director provides features for monitoring and managing Juniper Networks ACX Series routers, M Series routers, MX Series routers, and PTX Series routers. Connectivity between devices and their association with their location provide the foundation for rendering topology in a complete manner.

As a network administrator, you must have a clear understanding of the various networking devices in your network, their physical locations, and how these devices are interconnected in your network. The network topology represents the interconnection between various devices in your network, which are managed by Connectivity Services Director, based on their connectivity and association to their physical surroundings. The network topology provides a visual insight into the network, which is useful for debugging, troubleshooting, planning, and executing administrative actions.

Before you access the topological view of your network, you must:

  • Discover the devices managed by Connectivity Services Director in your network. For details about discovering devices, see Discovering Devices.

    Note

    You must specify the SNMP parameters during device discovery to have all the devices discovered and managed by Connectivity Services Director available in Topology View.

    Note

    Ensure that you have enabled the LLDP, STP, or RSTP protocols on the devices as Connectivity Services Director uses these protocols to determine the connectivity of devices with their neighbors in the network. LLDP and RSTP protocols are enabled by default on all MX Series routers.

Network topology enables you to view all the discovered devices in your network, where the devices are located along with their physical interconnection with other devices in your network. Topology also provides visualization around physical connectivity between various discovered interconnected devices. Multiple links displayed between nodes use line bending to avoid hidden trunks in the topology.

You can use the Topology View to zoom in or zoom out of a site to a group of devices and a group of devices to a site. In the Topology View, you can also double-click a site or a zone to view the devices in a site. You can also see the connectivity between a device and its immediate neighbors, alarms details, and so on.

Network topology also provides visualization around physical connectivity between various discovered interconnected devices. You can move the topology map by holding down the left mouse button, dragging the mouse to another point, and letting go of the mouse.
