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.

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 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.
