Managing the Topology View
Viewing the Network Topology
Topology View enables you to view all the discovered devices in your network, overlaid on a map. You can create sites, buildings, floors, outdoor areas, closets, and racks by using the Location wizard in Topology View. You can use the Topology View to zoom in or zoom out of a site or a building. You can also see the connectivity between a device and its immediate neighbors, alarms details, port details, and so on. An example of how the topology map looks like after you have added the location details is shown in Figure 1.
The topology display is created by layering the device images on top of the imported floor plan images.
In addition to the tasks outlined in the Topology View Tasks, you can perform the following tasks from the Topology View pane:
Zoom In and Zoom Out—You can use the zoom in () or zoom out() buttons to get a detailed or high-level view. Network Director enables you to zoom in and view details up to the rack level, if you have defined racks and assigned devices to the rack.
Pan—Network Director enables you to pan the topolog. You can move the devices to different parts on the topology by holding the mouse button down and dragging to a specific part of the map.
Network Director displays the sites, buildings, and geographical coordinates on the topology map based on the address specified while setting up the locations. However, you can move the devices around to another location by selecting, dragging, and dropping the device to the correct location. For example, you can move a site from a US site to a Bangalore site on the topology by using the Pan feature. This helps to determine the correct location of a site because while setting up the location details, it is not mandatory to provide the address information.
Search and Locate—You can search for all nodes such as sites, building, floors, specific devices, all devices in a floor, and so on by entering a search keyword or the complete name of the device in the Search field. On entering the search criteria, you might see the list of nodes or just one node based on the search criteria. When you select the node, Network Director locates the node and Topology View is panned to ensure the selected node is centered on the page. In cases where a device is at the edge of the map the corner is aligned accordingly to bring device in view.
View details—If you mouse over a entity (site, building, device), the entity gets highlighted and Network Director displays details such as the building name or IP address and the number of active alarms on that entity. A colored dot that appears on the upper right corner of the entity identifies whether there are alarms on the entity and the color of the dot indicates the severity level of the alarm. See Table 1 to know more about the alarm severity indicator for each alarm severity.
Table 1: Alarm Severity Indicator
Each of these entities might have alarms of different severities. Network Director displays the indicator based on the most severe alarm on an entity. For example, if a device has 3 informational alarms and one major alarm, Network Director displays the indicator for the major alarm ().
Highlight and select View Device Connectivity—Select a device and click View Device Connectivity, View VC/VCF Connectivity, or View Virtual Network Connectivity to view the selected device’s connectivity with other devices. Each of these tasks, except the View Device Connectivity, are visible only when you select a device that is part of a Virtual Chassis, Virtual Chassis Fabric, or a Virtual network. The device images are displayed along with details such as name, IP address, and the connectivity link between the devices.
Navigation—Use the navigation breadcrumbs at the top of the page to navigate through sites, buildings, floors, closets, or aisles. For there are more than one entities at any give level, you can use the Down arrow in the breadcrumb to navigate to that entity. For example, if you want to navigate from floor-1 in building-1 to floor-3 in building-2, you can use the down arrow in the building breadcrumb to select building-2 and the down arrow in the floor breadcrumb to select floor-3.
Host Information—You can use the button to expand the members to view the host details. You can also view the virtual machines if the host is a hypervisor and managed by Network Director.
Refreshing the Topology

as grey icons in the topology identifying the state of the member.
Mouse over a member to view details of that member.
In the Figure 7, the connection details are represented by green, yellow, and red lines.
The green line indicates that the node is connected to all the Interconnects properly and all functions are normal.
The yellow line indicates that the node is only partially connected to the Interconnect. That is, the node may be connected to one Interconnect, but not all the Interconnects.
The red line indicates that the node is not connected to any of the interconnects.
The following details are displayed in the top panel of the Virtual Chassis Topology View as shown in Table 4.
Table 4: Common Details for the Virtual Chassis and Virtual Chassis Fabric
All members of a Virtual Chassis configuration share one Virtual Chassis identifier (VCID). This identifier is derived from internal parameters.
The provisioning mode of the member. Provision mode can be autoprovisioned, preprovisioned or not preprovisioned.
Autoprovisioning a Virtual Chassis Fabric (VCF) enables you to “plug and play” devices into your VCF after minimal initial configuration.
In a VCF, you can have two to four members configured in the Routing Engine role. Of this, one member acts as the Master Routing Engine and another member acts as the backup Routing Engine. In a preprovisioned configuration, the selection of which member functions as the Master Routing Engine and which as the backup Routing Engine is determined by the software based on the primary-role election algorithm.
In a configuration that is not preprovisioned, the selection of the primary and backup is determined by the primary-role priority value and secondary factors in the primary-role election algorithm.
Indicates whether the Virtual Chassis is mixed or not.
The following details are displayed in the Virtual Chassis Topology view for each member depending on the role of the member as shown in Table 5.
Table 5: Details of VC/VCF Members
Name of the member switch provided while configuring the device. The device name is displayed as a label.
Serial number of the member switch.
Platform of the device. Platform can be QFX5100, QFX5110, or QFX10002.
The primary-role priority value. This is the most important factor in determining the role of the member switch within the Virtual Chassis configuration.
Operational role of the device. A device might be configured for a particular role, but can operate in the same or a different role. For example, a spine device configured with a Routing Engine role might operate as a line card. Therefore, the operational role of this device is Line Card.
Operational role can be Routing Engine or Line Card.
The configured role of the device. This can be Routing Engine or Line card.
Displays the status of each member device:
Present—The device is connected and working fine.
Not Present—The device is not connected to the VC or VCF.
Inactive—The device is connected, but not running.
Non Provisioned—A configuration in which the roles of the members are assigned automatically; not configured statically (preprovisioned).
Pre Provisioned—A configuration that allows you to deterministically control the member ID and role assigned to a member by associating the member with its serial number.
In addition to the above details, when you expand the host details, you can also view the details of the member and the link connected to the virtual machine.
