Configuring VMware ESXi for Active Directory (AD) authentication involves joining the ESXi host to the Active Directory domain and configuring user permissions accordingly. Here are the steps:

1. Access the ESXi Host:

• Connect to the ESXi host using the vSphere Client or vSphere Web Client.

2. Configure DNS Settings:

• Ensure that the DNS settings on the ESXi host are correctly configured, and it can resolve the Active Directory domain controller’s name. You can set the DNS configuration in the ESXi host under “Networking” > “TCP/IP Configuration.”

3. Join ESXi Host to Active Directory:

• In the vSphere Client, navigate to the “Host” in the inventory and select the “Configure” tab.
• Under the “System” section, select “Authentication Services.”
• Click “Join Domain” or “Properties” depending on your ESXi version.
• Enter the domain information, including the domain name, username, and password with the necessary permissions to join the domain.
• Click “Join Domain” or “OK.”

Example:

• Domain: example.com
• Username: domain_admin
• Password: ********

4. Verify Domain Join:

• After joining the domain, you should see a success message. If not, check the credentials and network connectivity.

5. Configure Permission:

• Go to the “Permissions” tab in the “Host” section.
• Add the AD user account to the appropriate role (e.g., Administrator or a custom role).

Example (PowerCLI):

New-VIPermission -Principal "EXAMPLE\domain_user" -Role "Admin" -Entity $esxiHost

6. Test AD Authentication:

• Log out of the vSphere Client and log in using an Active Directory account. Use the format “DOMAIN\username” or “username@domain.com” depending on your environment.

Example:

• Server: esxi.example.com
• Username: example\domain_user
• Password: ********

7. Troubleshooting:

• If authentication fails, check the ESXi logs for any error messages related to authentication or domain joining.
• Ensure that time synchronization is correct between the ESXi host and the domain controller.
• Verify that the Active Directory user account has the necessary permissions.

Note: Always refer to the official VMware documentation for your specific ESXi version for the most accurate and up-to-date information. The steps might slightly differ based on the ESXi version you are using.

Link Aggregation Control Protocol (LACP) is a standard that allows you to bundle multiple physical links together to increase bandwidth and provide redundancy. This is often used to improve network performance and ensure high availability. Below are the general steps to configure LACP on network devices such as switches:

1. Ensure LACP Support:

• Make sure that the network devices (usually switches) you are using support LACP.

2. Identify the Ports:

• Identify the physical ports on the devices that you want to aggregate. For example, if you have two switches, identify the ports on each switch that will be part of the aggregated link.

3. Access the Device Configuration:

• Access the command-line interface (CLI) or web-based management interface of your network device. This is typically done through a console cable, SSH, or a web browser.

4. Navigate to Port Configuration:

• In the device configuration interface, navigate to the port configuration section.

5. Configure LACP:

• Enable LACP on the ports that you want to aggregate. This is usually done by setting the aggregation mode to “Active” or “Passive” depending on your specific requirements.
• Active mode means that the port actively initiates the LACP negotiation.
• Passive mode means that the port responds to LACP negotiation but doesn’t actively initiate it.

Example (Cisco Switch CLI):

interface range GigabitEthernet0/1 - 2

channel-group 1 mode active

In this example, GigabitEthernet0/1 and GigabitEthernet0/2 are part of a channel group with mode set to active.

6. Configure the Same LACP Settings on the Other End:

• If you are aggregating links between two devices (like two switches), ensure that you configure the same LACP settings on the corresponding ports of the other device.

Example (Cisco Switch CLI – Other End):

interface range GigabitEthernet0/1 - 2

channel-group 1 mode active

7. Verify the Configuration:

• After configuring LACP on both ends, verify the status of the aggregated link to ensure that the LACP negotiation is successful and that the link is up.

Example (Cisco Switch CLI):

show lacp neighbor

show interfaces port-channel 1

These commands will show the LACP neighbors and the status of the aggregated link.

Keep in mind that specific commands and procedures may vary depending on the vendor and model of your network devices. Always refer to the documentation provided by your device’s manufacturer for accurate and device-specific information.

Remove the maintainer account (which allowed users to log in through the console after a hard reboot). Users who lose their password must have physical access to the FortiGate and perform a TFTP restore of the firmware in order to regain access to the FortiGate.
