1. Configure Microsoft Teams Incoming Webhook:

  • Log in to your Microsoft Teams account and navigate to the channel where you want to receive notifications.
  • Click on the three dots (…) next to the channel name and select “Connectors.”
  • Search for “Incoming Webhook” and click on it to configure.
  • Give your webhook a name and customize its settings, such as the icon that will be displayed with messages.
  • Once configured, a unique webhook URL will be generated. Copy and save this URL, as you’ll need it to send notifications from FortiGate to Teams.

2. Configure FortiGate Automation:

  • Access your FortiGate firewall’s web interface or CLI.

a. Define Triggering Events:

– Depending on your specific use case, you’ll want to define the events or conditions that trigger notifications. For example, you might want to send notifications when: – A critical security event is detected (e.g., intrusion attempts, malware activity). – A specific network condition is met (e.g., bandwidth threshold exceeded). – Configuration changes are made on the firewall.

b. Create a Custom Script or Action:

  • FortiGate Automation typically involves creating custom scripts or actions using FortiScript (for CLI-based automation) or FortiManager (for GUI-based automation).
  • Here’s an example of a custom FortiScript that sends a notification to Microsoft Teams using the webhook URL:
  # Define the Microsoft Teams webhook URL
  set teams_webhook_url "https://yourteamswebhookurl"

  # Define the message to send
  set message "A critical security event has been detected on FortiGate!"

  # Construct the JSON payload
  set json_payload '{"text": "'$message'"}'

  # Send the HTTP POST request to Microsoft Teams
  execute log "Sending Microsoft Teams notification..."
  execute external "post $teams_webhook_url" $json_payload

c. Customize the Message:

- You can customize the message within the script to include details about the triggered event, such as date, time, event type, and any relevant information.

3. Test the Automation:

  • To test the automation, trigger the event or condition that should initiate the notification. Check Microsoft Teams to ensure that the message is sent and received correctly.

4. Enable the Automation:

  • Once you have successfully tested the automation and are confident in its functionality, you can enable it in your FortiGate configuration.

5. Monitoring and Fine-Tuning:

  • Regularly monitor the automation to ensure that it continues to work as expected. If needed, you can make adjustments to the script or action to meet changing requirements or address any issues that may arise.

By following these detailed steps, you can set up a robust automation system within FortiGate to send Microsoft Teams notifications whenever specific events occur, helping you stay informed about critical network and security events in real-time.

Tagged Untagged Switch Configuration

Hello everyone , in this video I will describe and configure vlan on hp switch and assign vlans to ports as access and trunk. In HP (Hewlett-Packard) networking switches, “tagged” and “untagged” are terms commonly used to describe how VLANs (Virtual LANs) are handled on switch ports. Tagged ports are used to carry traffic for multiple VLANs simultaneously. These ports are typically used to interconnect switches or to connect devices that need to communicate with multiple VLANs. Tagged ports are also known as “trunk” ports in Cisco networking terminology. Untagged ports are used to connect end-user devices, such as computers, printers, or IP phones, to the network. Each untagged port is associated with a specific VLAN. Untagged ports are also known as “access” ports in cisco networking terminology.

Tagged Ports (Trunk Ports): Tagged ports are used to interconnect switches, routers, or other networking devices and carry traffic for multiple VLANs. They are configured with additional information called VLAN tags, which helps identify which VLAN each Ethernet frame belongs to. Here are the key details:

  • Port Configuration: To configure a port as tagged (trunk), you typically need to access the switch’s command-line interface or web-based management interface.

In Cisco devices, you might use commands like:

interface GigabitEthernet0/1

switchport mode trunk

switchport trunk allowed vlan 10,20,30

switchport trunk native vlan 10

In HP/Aruba switches, you might use commands like:

vlan 10

tagged 1-48

  • VLAN Membership: You specify which VLANs can traverse the tagged port using the “switchport trunk allowed vlan” (Cisco) or “tagged” (HP/Aruba) command. In the example above, VLANs 10, 20, and 30 are allowed to traverse the trunk port.
  • Native VLAN: The native VLAN is used for untagged frames on a tagged port. In the Cisco example, VLAN 10 is the native VLAN. Any untagged traffic entering the port is treated as part of this VLAN.

Untagged Ports (Access Ports): Untagged ports are used to connect end-user devices, such as computers, phones, or printers, to the network. They are associated with a single VLAN, and traffic on these ports is not tagged with VLAN information. Here are the key details:

  • Port Configuration: To configure a port as untagged (access), you typically follow a similar process as configuring tagged ports through the switch’s management interface or CLI.

In Cisco devices, you might use commands like:

interface FastEthernet0/1

switchport mode access

switchport access vlan 10

In HP/Aruba switches, you might use commands like:

vlan 10

untagged 1-48

  • VLAN Assignment: You specify which VLAN the port is associated with using the “switchport access vlan” (Cisco) or “untagged” (HP/Aruba) command. In the examples above, the port is assigned to VLAN 10.

Use Cases:

  • Tagged Ports: Tagged ports are used for scenarios where you need to carry traffic for multiple VLANs between network devices. Common use cases include connecting switches together, connecting to routers that perform inter-VLAN routing, and connecting to virtualization hosts where multiple virtual networks exist.
  • Untagged Ports: Untagged ports are used to connect end devices to the network. For example, a computer in a specific department would connect to an untagged port in that department’s VLAN, ensuring that all its traffic is part of that VLAN.

In summary, configuring tagged and untagged ports correctly is crucial for effective VLAN management. Tagged ports allow traffic from multiple VLANs to traverse a single physical link, while untagged ports connect end devices to a specific VLAN. This segmentation helps in maintaining network security, optimizing traffic flow, and organizing network resources.
