Configuring Ports and Devices

This chapter contains the following sections:

Cisco Monitor Manager Port Types

Cisco Monitor Manager allows 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—An edge port for incoming traffic connected to a physical tap wire.
  • SPAN ports—An edge port 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 a external monitoring device. When you configure a monitor 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 connecting it to the node.

Configuring a Port Type

    Step 1   In the topology diagram, click the node for which you want to configure a port.
    Step 2   In the Configure Network Device dialog box, click Configure Port Types.
    Step 3   Complete the following fields:
    Name Description

    Select a port drop-down list

    Choose the port that you want to configure.

    Select Port Type drop-down list

    Choose the port type for the port. This can be one of the following:

    • 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.
    • Delivery Port—Creates an outgoing port that can be connected to a monitoring device.
    • Unspecified Port—Creates an unspecified port. Unspecified ports cannot be used as edge ports or delivery ports.
    • Remove Configuration—Removes the existing configuration from a port.

    Set VLAN field

    The VLAN ID that you want to use for a SPAN or TAP port.

    Note   

    If you set a VLAN ID, you might override the current VLAN that is in the packet.

    Step 4   Click Configure.

    Configuring a Monitor Device

    Before You Begin

    You must configure a delivery port type before you can configure a monitor device.

      Step 1   In the topology diagram, click the node for which you want to configure a device.
      Step 2   In the Configure Network Device dialog box, click Configure Devices.
      Step 3   Complete the following fields:
      Name Description

      Select a port drop-down list

      Choose the delivery port for which you want to configure a device.

      Name field

      The name of the device.

      This name can be between 1 and 100 alphanumeric characters. You cannot use spaces or any special characters, and you cannot change this name after the object has been saved.

      Icon radio button

      The icon that you want to use for the device. The icon is displayed in the topology diagram.

      Step 4   Click Add Device.

      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 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.
