Managing Slices

This chapter contains the following sections:

About Slice Manager

The Slice Manager provides a way for you, as a network administrator, to partition networks into many logical networks. This feature allows you to create multiple disjoint networks and assign different roles and access levels to each one. Each logical network can be assigned to departments, groups of individuals, or applications. Multiple disjoint networks can be managed using the Cisco Nexus Data Broker application.

The Slice Manager creates slices based on the following criteria:

  • Network devices—The devices that can be used in the slice.

    Network devices can be shared between slices.

  • Network device interfaces—The device interfaces that can be used in the slice.

    Network device interfaces can be shared between slices.

  • Flow Specification—A combination of source and destination IP, protocol, and source and destination transport ports used to identify the traffic that belongs to the slice.

    Flow specifications can be assigned to different slices if the associated network devices and interfaces are disjointed.


    Note


    You can also use VLAN IDs to segregate the slice traffic.


Slices must be created by a Cisco Nexus Data Broker user with the Network Administrator role. After creation, the slices can be managed by a user with the Slice Administrator role.

Slices can overlap if each slice has at least one unique attribute. For example, a slice can share the same physical switches and ports, but be differentiated by the type of traffic it receives.

Adding a Slice

Procedure
    Step 1   From the Admin drop-down list, choose Management.
    Step 2   From the management Admin drop-down list, choose Slices.
    Step 3   From the Admin drop-down list, choose Slices.
    Step 4   On the Slices tab, click Add Slice.
    Step 5   In the Add Slice dialog box, complete the following fields:
    Name Description

    Slice Name field

    The name that you want to assign to the slice.

    The name may contain between 1 and 256 alphanumeric characters including the following special characters: underscore (_), hyphen (-), plus (+), equals (=), vertical bar (|), or at sign (@).

    Note   

    The slice name cannot be changed once it is saved.

    Static VLAN field

    The static VLAN that you want to assign to the slice.

    Step 6   Click Add Slice.

    Adding Nodes and Ports to a Slice

    Before You Begin

    You must have created a slice before you can add nodes and ports.

    Procedure
      Step 1   From the Admin drop-down list, choose Management.
      Step 2   From the management Admin drop-down list, choose Slices.
      Step 3   From the Admin drop-down list, choose Slices.
      Step 4   On the Slices tab, choose the slice for which you want to add entries.

      Enter a value in the Search combo box and click the search icon to limit the number of entries that appear.

      Step 5   In the topology diagram, click a node that you want to add to the slice.
      Step 6   In the Add Slice Entry dialog box, choose the port or ports that you want to add to the slice.
      Step 7   Click Add Entry.
      Step 8   Repeat Step 3 through Step 5 for each node and port that you want to add to the slice.

      Adding a Flow Specification

      Before You Begin

      Create a slice before you add a flow specification.


      Note


      Be default, a flow specification is bidirectional.


      Procedure
        Step 1   From the Admin drop-down list, choose Management.
        Step 2   From the management Admin drop-down list, choose Slices.
        Step 3   From the Admin drop-down list, choose Slices.
        Step 4   On the Flow Spec tab, choose the slice for which you want to add a flow specification.

        Enter a value in the Search combo box and click the search icon to limit the number of entries that appear.

        Step 5   On the Detail tab, click Add Flow Spec.
        Step 6   In the Add Flow Spec dialog box, complete the following fields:
        Name Description

        Name field

        The name that you want to use for the flow specification.

        The name can contain between 1 and 256 alphanumeric characters including the following special characters: underscore ("_"), hyphen ("-"), plus ("+"), equals ("="), open parenthesis ("("), closed parenthesis (")"), vertical bar ("|"), period ("."), or at sign ("@").

        VLAN field

        The VLAN ID or the range of VLAN IDs that you want to use for the flow specification.

        Source IP field

        The source IP address that you want to use for the flow specification.

        Destination IP field

        The destination IP address that you want to use for the flow specification.

        Protocol field

        The IP protocol number in decimal format that you want to use for the flow specification.

        Source Port field

        The source port that you want to use for the flow specification.

        Destination Port field

        The destination port that you want to use for the flow specification.

        Step 7   Click Add Flow Spec.
