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.

Fortigate Active Directory Integration

Hello everyone , in this video I will integrate my fortigate firewall with windows active directory , by doing this I can write the policies based on logged on users to their desktops , for example for one security group I can write a policy that can be access to facebook and for another group facebook will be blocked , or allow internet just for specific users that raised in security. Writing policies is depend on your environment.

1. Understanding Active Directory:

  • Active Directory is a Microsoft directory service that stores information about objects on a network, such as users, computers, groups, and more.
  • It provides centralized authentication and authorization services for network resources.

2. Purpose of Integration:

  • Integrating FortiGate with Active Directory helps streamline user authentication and access control for network resources.
  • It simplifies user management by allowing administrators to use AD user accounts for firewall policies.

3. Steps for FortiGate Active Directory Integration:

a. Configuration in Active Directory: – Ensure your Active Directory is properly configured with user accounts, groups, and organizational units (OUs).

b. FortiGate Web Interface Access: – Access the FortiGate web interface using a web browser.

c. Create a New LDAP Server Object: – Navigate to the “System” menu and select “Authentication” > “LDAP Servers.” – Click “Create New” to add a new LDAP server object. – Configure the LDAP server settings, including the server’s IP address or hostname, port (typically 389 for LDAP, 636 for LDAPS), and authentication credentials (usually a service account in AD).

d. Test LDAP Server Connectivity: – After configuring the LDAP server object, you can test the connectivity to ensure FortiGate can communicate with your AD server.

e. Create LDAP Authentication Group: – Go to “User & Device” > “User Definition” > “LDAP Servers.” – Create an LDAP authentication group and specify the LDAP server you created earlier.

f. Define Firewall Policies: – Create firewall policies that use LDAP authentication groups for user-based access control. – For example, you can define policies that allow or deny access to specific resources based on user group membership.

g. User Authentication: – When a user attempts to access a network resource, FortiGate will use the LDAP server to verify the user’s credentials. – Users will need to enter their AD username and password for authentication.

4. Additional Considerations:

  • Security: Ensure secure communication between FortiGate and Active Directory by using LDAPS (LDAP over SSL/TLS) for encrypted communication.
  • User Mapping: FortiGate can map AD groups to local FortiGate groups, simplifying policy management.
  • Fallback Mechanisms: Configure fallback authentication methods in case the LDAP server is unreachable or for users not in AD.

5. Monitoring and Maintenance:

  • Regularly monitor the integration for any issues, such as LDAP server connectivity problems or changes in AD group memberships.
  • Keep FortiGate and Active Directory servers up-to-date with security patches.
