Link Aggregation

Link Aggregation allows one or more full-duplex Ethernet links to be aggregated together to form a Link Aggregation Group (LAG). The switch treats the LAG as if it is a single physical port, with improved fault tolerance and load- sharing capability.

A LAG interface can be either static or dynamic:

Static LAG—Ports are assigned to a LAG directly by the administrator. The ports remain dedicated LAG members until configured otherwise.

Dynamic LAG—A dynamic LAG is configured with one or more candidate ports. The LAG is formed by exchanging Link Aggregation Control Protocol Data Units with the remote device connecting to the candidate ports. When formed, the LAG might include only a subset of the eligible ports, depending on the port number limitations for LAGs and other factors. Candidate ports that are not selected as active member ports of a LAG are standby ports. A standby port may be selected as an active member when an active port in the same LAG fails.

The following topics provide additional information on the configuration pages available in the Port Management > Link Aggregation menu:

Configuring LAGs

The switch supports up to 4 LAGs, with 8 ports per LAG. Use the LAG

Management page to assign ports to LAGs and LACPs.

To display this page, click Port Management > Link Aggregation > LAG

Management in the navigation window.

Four dynamic LAGs are preconfigured by default named ch1 through ch4. They have no port members and are disabled.

You can add or remove ports to or from a LAG without disrupting traffic on the

LAG.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
