Configuring Ports and Devices

This chapter contains the following sections:

About Cisco Monitor Manager Port Types

Cisco Monitor Manager enables you to configure different port types. All configured ports are displayed in the Configured Ports table on the Port Types tab.

Edge Ports

Edge ports are the ingress ports where traffic enters the monitor network. Cisco Monitor Manager supports the following edge ports:

  • TAP ports—For incoming traffic connected to a physical tap wire.
  • SPAN ports—For incoming traffic connected to an upstream switch that is configured as a SPAN destination.

Configuring an edge port is optional.

Delivery Ports

Delivery ports are the egress ports where the traffic exits the monitor network. These outgoing ports are connected to external monitoring devices. When you configure a monitoring device in Cisco Monitor Manager, you can associate a name and an icon with the switch and port that you configured.

Configured devices are displayed in the Monitor Devices table on the Devices tab. The icon appears in the topology diagram with a line that connects it to the node.

VLAN Double Tagging

Cisco Monitor Manager enables you to configure a switch port as an edge port and specify a VLAN for that port. When you configure the VLAN ID, and the connection to the Cisco onePK agent is up, Cisco Monitor Manager programs the Cisco Nexus 3000 or 3100 Series switch so that all packets received in that port are VLAN tagged, and the VLAN ID is the one configured on the edge port. If the packets received in that port are already VLAN-tagged frames, they get double-tagged, and the outermost VLAN tag contains the VLAN ID that is associated with the configured edge port.

Configuring a Port Type

    Step 1   In the topology diagram, click the node for which you want to configure a port. The Ports area of the sidebar displays the list of ports available to configure for that node.
    Step 2   In the list of ports for the node, click Click to configure under the port identifier of the port that you want to configure.
    Step 3   From the Select a port type drop-down list, choose one of the following:
    • Edge Port-SPAN
    • Edge Port-TAP

    Edge Port-SPAN—Creates an edge port for incoming traffic connected to an upstream switch that is configured as a SPAN destination.

    Edge Port-TAP—Creates an edge port for incoming traffic connected to a physical TAP port.

    Step 4   (Optional)In the Port Description field, enter a port description.

    The port description 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 ("@").

    Step 5   (Optional)Enter a VLAN ID.

    The port is configured as dot1q to preserve any production VLAN information.

    Step 6   Click Submit. The port type configuration is saved and displayed in the description of the port under the node identifier.

    Removing a Port Type Configuration

      Step 1   In the topology diagram, click the node for which you want to remove a port configuration. The Port Types tab displays the list of ports available to configure for that node.
      Step 2   In the list of ports for the node, click the identifier of the port for which you want to remove the configuration.
      Step 3   In the left pane, click the Edge Port-SPAN or Edge Port-TAP link. The link displayed depends on the type of port that was configured.
      Step 4   From the drop-down list, choose Remove Configuration.

      The port type configuration is removed.

      Configuring a Monitor Device

        Step 1   In the topology diagram, click the node for which you want to configure a monitoring device. The Port Types tab displays the list of ports available to configure for that node.
        Step 2   In the list of ports for the node, click Click to configure under the port identifier of the port that you want to configure.
        Step 3   Click Add Monitoring Device.
        Step 4   In the Add Device dialog box, complete the following fields:
        Name Description

        Device Name field

        The name you want to use for the monitoring device.

        You can edit the name of the monitoring device after it has been added.

        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 ("@").

        Icons selection

        The choice of icons, with the first one selected by default. Choose any icon to use for the monitoring device.

        You can edit the monitoring device icon after the monitoring device has been added.

        Step 5   Click Submit.

        Removing a Monitoring Device

        Before You Begin

        At least one monitoring device must be configured for the port.

          Step 1   In the topology diagram, choose the node from which you want to remove a monitoring device.
          Step 2   Next to the port name for which you want to remove monitoring devices, click the Devices highlight.
          Step 3   In the expanded Device Name list for the port, choose one of the following:
          • The top checkbox to select all monitoring devices for removal
          • The checkbox next to the name of only the monitoring device or devices you want to remove
          Step 4   Above the Device Name list, click Remove Monitoring Devices.
          Step 5   In the confirmation dialog box, click Remove Devices.

          Configuring a Root Node

          A root node is automatically selected by Cisco Monitor Manager. If the defined root node is too far from the source switches, you can manually configure a different switch. We recommend that you choose a switch with edge ports as your new root node.


          Note

          Root node changes do not take effect until you save the configuration and restart the Cisco Extensible Network Controller (XNC) application.

            Step 1   On the Root tab, click Configure Root.
            Step 2   In the Configure Root Node dialog box, choose a node in the Select Root Node drop-down list.
            Step 3   Click Configure.
            Step 4   Restart Cisco Monitor Manager.

            Cisco onePK Agent

            The Cisco onePK plug-in for Cisco Extensible Network Controller (XNC) communicates with onePK devices through a onePK agent on the device. To support onePK device functions in Cisco Monitor Manager, the application must be connected to the onePK agent. The agent is the mediator between Cisco Monitor Manager and onePK-enabled devices that are configured in Cisco Extensible Network Controller (XNC).

            To secure communication between Cisco Extensible Network Controller (XNC) onePK-enabled devices, you must configure Transport Layer Security (TLS) in Cisco Extensible Network Controller (XNC). See the Cisco Extensible Network Controller Deployment Guide, Release 1.6 for detailed procedures.

            Connecting to a onePK Agent

            You must connect to a onePK agent to support additional functionality in Cisco Monitor Manager, including symmetric load balancing and Q-in-Q.

              Step 1   In the topology diagram, click the node to which you wish to connect a onePK agent.

              Step 2   In the sidebar, click Click to enable addtional functionality.
              Step 3   In the Connect to onePK agent dialog box, complete the following fields:
              Name Description

              Address field

              The IP address assigned to the Cisco onePK device.

              Username field

              The username of the user that you want to assign to the device.

              Password field

              The password of the user that you want to assign to the device.

              Step 4   Click Submit.

              Symmetric Load Balancing

              Cisco Monitor Manager enables you to configure symmetric load balancing settings on the egress port channels. Load balancing settings are based on Layer 2 source MAC and destination IP addresses, or Layer 2, Layer 3, or Layer 4 source and destination ports. When you configure symmetric load balancing for all the port-channel interfaces on the switch, all the traffic from specific sources and destinations in both directions always flows on the same port-channel member link.


              Note

              Symmetric load balancing in Cisco Monitor Manager is available only for Cisco Nexus 3100 Series switches.

              Configuring Symmetric Load Balancing


              Note

              The ability to configure symmetric load balancing is available only for Cisco Nexus 3100 Series switches.

              Before You Begin
              • Configure a onePK agent for the node.
              • Configure and provision TLS on the switches. See the Cisco Extensible Network Controller Deployment Guide, Release 1.6 for detailed TLS setup procedures.
                Step 1   In the topology diagram, click the node for which you wish to configure symmetric load balancing.
                Step 2   In the side bar, from the Symmetric Load Balancing drop-down list, choose one of the following:
                • SOURCE_DESTINATION_IP—source and destination IP address (includes Layer 2)
                • SOURCE_DESTINATION_IP_ONLY—source and destination IP addresses only
                • SOURCE_DESTINATION_PORT—source and destination TCP/UDP port (includes Layer 2 and Layer 3)
                • SOURCE_DESTINATION_PORT_ONLY—source and destination TCP/UDP port only
                Step 3   Click Submit.

                Configuring Q-in-Q


                Note

                The ability to configure Q-in-Q is available only for Cisco Nexus 3000 and 3100 Series switches. Q-in-Q is automatically enabled when you configure a VLAN ID for an edge port, if the VLAN ID is maintained on the edge port.

                Before You Begin

                Connect to the onePK agent for the node.

                  Step 1   In the topology diagram, click the node for which you wish to configure Q-in-Q.
                  Step 2   In the side bar, configure an edge port and set a VLAN ID on that edge port.
