Show CDP Neighbor of Cisco UCS Uplinks

There are two ways to know which network switch ports the network uplinks of Cisco UCS Fabric Interconnects are connected to.

By CLI



  • SSH to the Cisco UCS Manager.

  • Connect to FI-A.


# connect nxos a


  • Show neighbor of network uplinks.


# 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.


# Connect-Ucs <UCS FQDN>


  • Show CDP neighbor details.


# Get-UcsNetworkLanNeighborEntry

Side notes


Following command can shows network switch name, network switch ports and FI ports
# Get-UcsNetworkLanNeighborEntry | Select deviceid,remoteinterface,localinterface

If you prefer to enable the "Info Policy" by PowerShell, run following command
# Get-UcsTopInfoPolicy | Set-UcsTopInfoPolicy -State enabled -Force

Connect-NsxtServer shows "Unable to connect to the remote server"

When you run Connect-NsxtServer in the PowerCLI, it may show "Unable to connect to the remote server".  Because the error message is a little bit confusing with other login issues. It's not easy to troubleshoot. The actual reason is the NSX-T uses a self-signed certificate, and the PowerCLI cannot accept the certificate automatically. The fix is super easy. You need to set the PowerCLI to ignore the invalid certificate with the following command: Set-PowerCLIConfiguration -Scope User -InvalidCertificateAction:Ignore -Confirm:$false

Setup Terraform and Ansible for Windows provisionon CentOS

Provisioning Windows machines with Terraform is easy. Configuring Windows machines with Ansible is also not complex. However, it's a little bit challenging to combine them. The following steps are some ideas about handling a Windows machine from provisioning to post configuration without modifying the winrm configuration on the guest operating system. Install required repos for yum. yum -y install https://repo.ius.io/ius-release-el7.rpm yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm yum -y install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm yum -y install epel-release yum -y install yum-utils yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo Install  Terraform . sudo yum -y install terraform Install  Ansible . sudo yum -y install ansible Install  Kerberos . yum -y install gcc python-devel krb5-devel krb5-libs krb5-workstation

How to List All Users in Terraform Cloud

Terraform has a rich API. However, the API documentation does not mention how to list all users. We can leverage the organization membership API and the PowerShell command  Invoke-RestMethod  to get a user list. 1. Create an organization token in Terraform Cloud. 2. Create the token variable ( $Token ) in PowerShell. $Token = "abcde" 3. Create the API parameters variable in PowerShell. $params = @{ Uri = "https://app.terraform.io/api/v2/organizations/ZHENGWU/organization-memberships?page%5Bsize%5D=100" Authentication = "Bearer" Token = $Token ContentType = "application/vnd.api+json" } Note: You need to replace ZHENGWU with your own organization name. And I used 100 at the end of the URI to retrieve the first 100 users. It can be any number.  4. Retrieve the API return and list the user's email address. $Test = Invoke-RestMethod @params $Test.data.attributes.email
