By CLI

• SSH to the Cisco UCS Manager.
• Connect to FI-A.

# connect nxos a

# show cdp neighbor interface ethernet <port num>

By PowerShell

• Make sure Cisco PowerTool (For UCS Manager) is installed.
• Enabling the Information Policy via UCSM GUI.
  • Go to “Equipment” -> “Policies” tab -> “Global Policies” tab -> “Info Policy” area.
  • Change to “Enabled“. (No impact to running blades)
• Open a PowerShell window.
• Connect to the UCS Manager.
