On the Devices screen, the following tabs are displayed:

• Nodes Learned

• Device Connections

• Device Groups

• SPAN Management

• Subnet Gateway Configuration

On the Nodes Learned tab, the following details are displayed for each node:

• The name of the node

• The ID of the node

• The hardware on the node

• The number of ports on the node

When you click the node name under the tab Node Name, the Update Node Information window is displayed. Update the following fields in the window:

• Node ID: Enter the node ID.

• Node Name: The name of the node.

• Tier: Select the tier of the node from the following options in the drop-down list: Unknown, Access, Distribution, and Core.

• Operation Mode: 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 Address Resolution Protocol (ARP) packets.

  • Punt Link Layer Discovery Protocol (LLDP) packets.

  • Drop all other traffic.

On the Device Connections tab, click Add Device to add a device, click Remove Devices to remove a device, or click Rediscover Devices to rediscover a device. When you click Rediscover Devices tab, the Rediscover Device window is displayed. Click Rediscover Device so that the device gets deleted and rediscovered again.

In each device window, click View, Edit, or Delete to add a device, edit an existing device, or delete a device. The following details are displayed for each device in each device window:

• The name of the device and its IP address

• The username on the device

• The type of the mode, for example, NX-API

• The uptime on the device, for example, date and time

• The hardware on the node

On the Device Groups tab, click + Group to add a group of devices. In each group window, click View, Edit, or Delete to add a group of devices, edit an existing group of devices, or delete a group of devices respectively. The following details are displayed in each group window:

• The name of the node group, for example, Node Group Name One

• The names of the nodes in the group, for example, nx-tap-agg-sw1 and nx-tap-agg-sw2

On the SPAN Management tab, click + Add Device to add an APIC device or the production switch to the network. Click Remove Devices to delete the devices or click Rediscover Devices to rediscover the devices. The production switch should be a Cisco Nexus 9000 Series switch or Cisco Nexus 3000 Series switch in NXOS mode. The feature NXAPI has to be enabled on these production switches.

The following columns are displayed on the SPAN Management tab to display the information about the devices:

• IP Address

• Username

• Type: The APIC device is listed as AC and the production switch will belated here is listed as PS.

• Active IP

• Secondary IP Address
