Chapter: Managing Inventory

Managing Inventory

You can discover the devices using the auto discovery option, and import the details into Cisco VTS. You can also manually create a CSV file with device details, in a prescribed format, and import it into Cisco VTS.

You can create authorization groups and assign devices you import into Cisco VTS, to these groups. Authorization groups are used to group devices with the same credentials (i.e. usernames and passwords). Once the authorization groups are created, all the devices under these groups may be accessed without specifying the credentials every time they are accessed.

If the same credential are used for accessing all devices, one authorization group can be used. If the credentials are different for different devices, multiple authorization-groups (as many as username/password pairs used by devices) need to be created.

When you do a manual import of devices, the CSV file that is used to import inventory details links the authorization group with a specific device. The applicable authorization group should be used for corresponding device entry in the CSV file.

This chapter has the following sections:

Creating Authorization Groups

Authorization Group is used by Cisco VTS to authenticate or to log in to the device.

To create an authorization group:

    Step 1   Go to Inventory > Authorization Group. The Inventory / Authorization Group window appears.
    Step 2   Click Add (+) icon. The Add Auth Group popup window appears.

    Enter the following details, and click Save:

    • Auth Group Name—The authorization group name.

    • Controller User Name—This is the VTC administrative user name.

    • Device User Name—This is the login user name for the device.

    • Password—This is the login password for the device.

    The authorization group gets added to the Groups table.

    To edit an authorization group, select the Auth Group Name check box and click the Edit icon.

    To delete an authorization group, select the Auth Group Name check box and click the delete (X) icon.

    Importing Inventory

    The device inventory details need to be uploaded using a CSV file, in the prescribed format. The inventory file is used to define device mappings. If the format is incorrect, Cisco VTS displays an error and provides the details of the error. After a successful import, the topology gets displayed based on the mapping specified in the file.


    Note
    You should be an admin user to download or upload the CSV file. Also, if you are uploading a CSV file for the first time and there are issues uploading the file, then only the partial information is uploaded. You need to delete all the devices from network inventory and re-upload the file after fixing the issues. Or else, you may encounter problems due to the partial upload.

    To download a sample inventory file, click Download Template.


    Note
    In a VMware environment, each time you add a leaf, you must create a corresponding VMware vSphere Distributed Switch (VDS). See the Creating the VMware vSphere Distributed Switch (VDS) section for details.
      Step 1   Go to Inventory > Import Inventory. The Inventory / Import Inventory window appears.
      Step 2   In the Import Inventory page, click Browse to choose the file.

      Click the ? icon to view details about the format of the CSV file you should upload.

      The CSV file has the following fields:

      • device-name—The device host-name (leaf, spine, DCI)

      • device-ip—IP address for the device (leaf, spine, DCI)

      • device-platform—Can be Cisco Nexus 9000, Cisco Nexus 7000 etc based on the device that is part of the network.

      • device-role—The role that a particular device plays in the data center.

        • leaf—If the device plays the role of a Leaf in the data center.

        • border leaf—If the device plays the role of a Border Leaf in the data center.

        • spine—If the device plays the role of a Spine in the data center.

        • spine-rr—If the Spine plays the role of a Route Reflector in the data center.

        • dci—If the device plays the role of a DCI in the data center.

      • group-tag—Identifier for the group.

      • port-name—Physical port connectivity (local interface)

      • connection-type—server (if connected to compute host); fabric (if connected to another leaf, spine, DCI devices).

      • server-id—Host-name or IP address of the connected device based upon what is configured on the actual host.

      • server-type—virtual-server for computes; baremetal for connections to spine, DCI.

      • interface-name—Physical port connectivity (interface of the connected device)

      • auth-group—Authorization group name, created as part of initialization, with correct credentials.

      Step 3   Browse for the CSV file, and click OK.

      Viewing the Network Topology

      Topology window provides a view of the data center fabric controlled by Cisco VTS. It displays the leafs, spines, border leafs, DCI, hosts, as well as the software VTEPs. You can get a tenant-based topology view using this feature.

      To view the network topology:

        Step 1   Go to Inventory > Topology. The Inventory / Topology window appears.
        Step 2   Select the tenant for which you need to view the topology, from the Select Tenant drop down list.

        The topology is displayed in the Topology window. You can use the following buttons to control the display:

        • Select node mode

        • Move mode

        • Zoom in / Zoom out / Zoom Selection

        • Fit Stage

        • Full Screen mode

        Hover the mouse cursor over the Topology Setting icon to view Topology Setting popup, where you can change the display icon appearance, and display color.

        Viewing Network Inventory

        The network inventory table displays details about the devices which have been added to the inventory.

        To view the network topology:

        Go to Inventory > Network Inventory. The Inventory / Network Inventory window appears with the Network Inventory table displayed.

        The following details are displayed:

        • Device Name

        • Admin State

        • IP Address

        • Auth Group

        • Device Platform

        • Device Role

        • Group Tag

        • bgp-asn

        • Loopback Interface Number

        • Loopback Interface IP

        Note   

        You need to add the bgp-asn information, loopback interface number, and loopback interface id of every device prior to starting any provisioning.

        You can add network devices via the Network Inventory table. To do this, click the Add (+) icon, and provide the details. You can use this option to add devices to the inventory.

        To edit network device, select the device you want to edit and click the Edit icon.

        To delete network devices from the Network Inventory table, select the device you want to delete and click the Delete (X) icon.
        Note   

        It is important that you remove the resource pool before deleting a device.

        To add fabric connection:

          Step 1   Go to Inventory > Network Inventory. The Inventory / Network Inventory window appears with the Network Inventory table displayed.
          Step 2   Click Fabric Connection tab, then click Add (+) icon.

          The Add Fabric Connection popup window appears.

          Step 3   Enter the necessary details and click Save.

          Viewing Host Inventory

          You can view the details of the hosts connected to the switches. To view host inventory details:
            Step 1   Go to Inventory > Host Inventory. The Inventory / Host Inventory window appears
