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 12.

Figure 12: Main Topology Window

Main Topology Window

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:

Refreshing the Topology

You can refresh the devices discovered and managed by Network Director from the Tasks pane in the Topology View and the Datacenter View. You can add the Refresh Topology task to the Key tasks in both the views if you will use this task frequently.

Procedure

To refresh the device discovery process:

  1. Click Refresh Topology from Key Tasks or the Topology View, or from the Datacenter Discovery panes.

    The Refresh Discovery window is displayed along with the SNMP details that you specified in the discovery options in the Device Discovery task page.

    If you have not specified the SNMP details while discovering the devices, proceed to Step 3.

  2. Select the SNMP version from the SNMP version table and click Discover. The Refresh Topology window appears displaying the progress of the topology discovery.
  3. If SNMP version details are not displayed in the SNMP version table, click Add on the Refresh Discovery window.

    The Add SNMP Settings dialog box is displayed.

    Select either SNMP V1/V2C or SNMP V3. Based on the selection, you need to enter the details as follows:

    • If you selected SNMP V1/V2C, specify a community string, which can be public, private, or a predefined string.

      Click Add in the Add SNMP Settings dialog box or click Add More to add more strings to the community. If you click Add More, when you are done adding all the strings, click Add to save the SNMP settings for V1/V2C.

    • If you selected SNMP V3, specify the following:
      • Enter a username.
      • Select the privacy type (AES 128, DES, or None).
      • Enter the privacy password (if AES 128 or DES). If you specify none for the privacy type, the privacy function is disabled.
      • Select the authentication type (MD5, SHA, or none).
      • Enter the authentication password (if MD5 or SHA). If you specify none for the authentication type, the authentication function is disabled.
      • Click Add to save the SNMP settings and close the dialog box, or click Add More to add additional configurations. If you clicked Add More, click Add to save the settings and close the dialog box.

      The specified details are displayed in the SNMP version table.

  4. Click Discover.

    The Refresh Topology window is displayed, showing details of the device discovery.

Displaying QFabric Connectivity

You can view the QFabric devices available in your network by navigating to the rack, closet, or floors from the Topology View. Alternatively, you can search for the QFabric devices by entering a search criteria in the Search field. You can also assign the QFabric devices to a rack, closet, or floor from Topology View.

Network Director enables you to view the data plane topology and the control plane topology from the Fabric Connectivity page. Data plane is a redundant, high-performance, and scalable data plane that carries QFabric system data traffic. Control plane constitutes of the internal network connection that carries control traffic between the various QFabric system components such as node devices, interconnect devices, director group processes, and the control plane Ethernet switches.

You can view the connection details of the QFabric Interconnects with the nodes by using all views except the Dashboard View and Datacenter View.

To view the connection details of the QFabric devices:

Do one of the following:

Click Connectivity > View QFabric Connectivity from the Tasks pane. Network Director displays the QFabric connectivity in the Data plane—with the interconnect in the center surrounded by the nodes— as shown in Figure 18. Mouse over a device to view the port details and the connection state of that device.

By default, Network Director displays the Data plane topology for the selected QFabric. To view the control plane topology, click Control Plane.

Displaying Virtual Chassis and Virtual Chassis Fabric Connectivity

You can view the connectivity between the components of Virtual Chassis and Virtual Chassis Fabric using the View VC/VCF Connectivity task. You can access this tasks from all views except Dashboard View and Datacenter View.

Procedure

To view the connectivity details for a Virtual Chassis or a Virtual Chassis Fabric:

  1. Do one of the following:
    • While in the Logical, Location, Device, or Custom View, select the device for which you want to view the Virtual Chassis or Virtual Chassis Fabric connectivity from the View pane and click Connectivity > View VC/VCF Connectivity from the Tasks pane.
    • In the Topology View, navigate to a device in a building, floor, outdoor area, closet or rack and select the device for which you want to view the Virtual Chassis or Virtual Chassis Fabric connectivity details and click Connectivity > View VC/VCF Connectivity from the Topology Tasks pane.

      Note: The Connectivity task container is available only after you select a device.

  2. Click Connectivity > View VC/VCF Connectivity from the Tasks pane. Network Director displays the connectivity between the members of the selected Virtual Chassis as shown in Figure 19. The inactive members and any members having alarms in down state are shown as grey icons in the topology identifying the state of the member. Mouse over a member to view details of that member.

    Figure 19: Displaying the Connectivity for a Virtual Chassis Fabric

    Displaying
the Connectivity for a Virtual Chassis Fabric

    The following details are displayed in the top panel of the Virtual Chassis Topology View as shown in Table 45.

    Table 45: Common Details for the Virtual Chassis and Virtual Chassis Fabric

    Details

    Desciption

    Fabric ID
    VC ID

    All members of a Virtual Chassis configuration share one Virtual Chassis identifier (VCID). This identifier is derived from internal parameters.

    Provisioning Method

    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 master-election algorithm.

    In a configuration that is not preprovisioned, the selection of the master and backup is determined by the mastership priority value and secondary factors in the master-election algorithm.

    VC Mode

    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 46.

    Table 46: Details of VC/VCF Members

    • 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.
