Viewing Data Center Connectivity
After you have set up a data center in Network Director, you can pictorially view the physical connectivity between the network devices and the bare metal server, the hypervisor server, or both, using the View Connectivity task. This view also displays all the virtual machines (VMs) that are part of each data center.
To view the connectivity between the physical and virtual devices in a data center:
- While in Build mode with Datacenter View selected, select
a data center from the View pane and click Connectivity > View Connectivity from the Tasks pane.
The Datacenter Connectivity page opens displaying the connections between the network devices and the data center servers (hypervisor servers and bare metal servers).
- You can perform the following tasks from the Datacenter
View the connectivity between switches, between switches and hosts, and between hosts and virtual machines. When you open the Datacenter Connectivity page, Network Director displays the connectivity between switches and switches to hosts as shown in Figure 1.
You can view port utilization between switches, and switches and host servers by selecting the Color Coded Port Utilization check box. Use the legend displayed on this page to infer the port utilization on each link. You can also mouse over each link to know the exact port utilization on that link. Figure 1 displays the use of color coded port utilization legend.
To view the connectivity between a host and virtual machines, click the host or click the Device button and select VMs check box as shown in Figure 2.
To view only the connectivity between the switches, clear the Servers check box and the VMs check box as shown in Figure 3.
Manual NIC associations are used for orchestration purpose only, and are not visible in the Datacenter Connectivity page.
Disable the topology updates to the current view by clicking Disable Updates.
Mouse over each entity to know more details about that entity.
You can zoom in or zoom out of the connectivity view by using the + and - buttons.
View the type and number of faults and alarms on Juniper Networks devices. The color that outlines each device indicates whether there are alarms on that device. Network Director also displays a count of the number of alarms of the highest severity on that device in this page.
Table 1 describes what each device icon that appears in the Datacenter Connectivity page indicates.
Table 1: Datacenter Connectivity View—Device Icon Legends
The device is a switch that has no faults or alarms.
The device is a bare metal server.
The device is a hypervisor server (KVM or ESXi host).
The device is not managed by Network Director.
The device has one critical alarm.
The device has one major alarm.
The device has one informational alarm.
View more details about the alarms present on a device. Zoom in to the device and click the device. Details about the device and the alarms are displayed. Click the alarm count to view more details about that alarm. Network Director opens the Fault mode and displays details about the alarm.
- To view the virtual tunnel end points (VTEPs) in your
data center network, click the down arrow in the Overlay button and select Show VTEPs as shown in Figure 4.
Network Director highlights and displays the VTEPs in your data center in the Datacenter Connectivity page.
- To view the overlay connectivity, do one of the following:
To view the overlay network connectivity based on the VNI number, click the down arrow in the Overlay button, select the Overlay Network check box, and select a VNI number from the list.
Network Director highlights the VXLAN connectivity between the various entities for the selected VNI as shown in Figure 5.
To view the overlay networks for a tenant, click the down arrow in the Overlay button, select the Tenant check box, and select a tenant name from the list.
Network Director highlights the overlay network between the various entities for the selected tenant.
This option is not available for data centers that use NSX as the cloud service provider.
- Select Stop Updates, to stop the link status changes in real time in the Datacenter Connectivity page that might occur while the user is performing some tasks in this page.
