Managing Devices

This chapter contains the following sections:

Adding a Node Name

Adding user-friendly node names will help you to identify nodes in the topology diagram.

    Step 1   On the Cisco XNC menu bar, click Devices.
    Step 2   On the Nodes Learned tab, click the link for the node that you want to rename in the Node Name column.
    Step 3   In the Update Node Information dialog box, complete the following fields:
    Name Description

    Node ID field

    The unique identifier for a network element, such as an OpenFlow switch.

    Node Name field

    The name that you want to assign to the node.

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

    Tier drop-down list

    Assign the tier property for the network element. This can be one of the following:

    • Unknown
    • Access
    • Distribution
    • Core

    Operation Mode drop-down list

    Choose how the traffic is handled based on the flows. This can be one of the following:

    • Allow reactive forwarding—No default flows are programmed. How traffic that does not match a flow is treated depends upon the switch implementation.
    • Proactive forwarding only—The following default flows are programmed on the switch:
      • Punt ARP packets to Cisco XNC.
      • Punt LLDP packets to Cisco XNC.
      • Drop all other traffic.
    Step 4   Click Save.

              Adding a Node Group

              A node group allows you to visually group nodes in the Cisco XNCtopology diagram. Node groups do not create links between nodes.

                Step 1   On the Cisco XNC menu bar, click Devices.

                Step 4   Click Add Group. The name of the group displays in the list of Node Groups.
                What to Do Next

                Add nodes to the node group.

                Adding Nodes to a Node Group

                Adding nodes to a node group visually associates the nodes with the node group in the topology diagram. Node groups are highlighted in color in the diagram.


                Note

                If you add a node that already belongs to a node group to a node to new node group, it will automatically be removed from the first node group and added to the new node group.

                Before You Begin

                Add a node group.

                  Step 1   On the Cisco XNC menu bar, click Devices.
                  Step 2   Click the Device Groups tab.
                  Step 3   Click the Name of the node group to which to want to add nodes in the Node Groups list.
                  Step 4   To add nodes to the group, you can either:

                  • Click one or nodes in the topology diagram, then:
                  1. Click Add to group <group name> in the topology diagram.
                  • Or, click the Nodes in Group tab, then:
                  1. In the Add Nodes to Group - <group name> dialog box, select one or more nodes from the drop-down list.
                  2. Click Add to group.
                  The nodes display in the Nodes in Group - <group name> list on the Nodes in Group tab, and in the node group in the topology diagram.

                  Removing Nodes from a Node Group

                  Before You Begin

                  Add nodes to a node group.

                    Step 1   On the Cisco XNC menu bar, click Devices.
                    Step 2   Click the Device Groups tab.
                    Step 3   Click the Name of the node group from which to want to remove nodes in the Nodes Groups list.
                    Step 4   To remove nodes from the group, you can either:

                    • Click a node group in the topology diagram, then:
                    1. Click the node you want to remove from the group.
                    2. Click Remove from group <group name> in the topology diagram.
                    • Or, click the Nodes in Group tab, then:
                    1. Click the checkbox next to the node or nodes you want to remove in the list of Nodes in Group <group name>, or click the top checkbox in the list to select all nodes in the group for removal.
                    2. Click Remove Nodes from - <group name> .
                    Step 5   In the confirmation dialog box, click Remove.

                    Removing a Node Group

                    Removing a node group disassociates the nodes added to it from the node group, and the node group will no longer be displayed in the topology diagram.

                      Step 1   On the Cisco XNC menu bar, click Devices.
                      Step 2   Click the Device Groups tab.
                      Step 3   In the Node Groups list, click the checkbox next to the Name of the node group you want to remove, or click the top checkbox to select all node groups for removal.
                      Step 4   Click Remove Group.
                      Step 5   In the confirmation dialog box, click Remove Group. The node group is removed and no longer displays in the topology diagram.
