Configuring Port Settings

 

 

 

 

 

Administrative Duplex Mode—If Auto Negotiation is disabled, select Half for half-duplex or Full for full-duplex operation.

Admin Advertisement—If Autonegotiation is enabled, select the highest port speed and duplex setting that you want the port to negotiate. If you select Max Capacity, the port autonegotiates up to the highest port speed and duplex setting supported by hardware.

Flow Control—Select to enable IEEE 802.3x flow control. Flow control reduces data loss when the port cannot keep up with the number of frames being switched. When enabled, the switch can send a PAUSE frame to stop traffic on a port if the amount of memory used by packets on the port exceeds a preconfigured threshold. The paused port does not forward packets for the period of time specified in the PAUSE frame. When the PAUSE frame time elapses or memory utilization falls below a specified low threshold, the switch enables the port to again transmit frames. When the mode is set to half–duplex, back pressure is exerted; however, we recommend that Flow Control be enabled.

Member in LAG—Indicates whether the port is a member of a Link Aggregation Group. See Link Aggregation for information on configuring LAGs.

MTU—Specify the maximum transmission unit size in bytes. The default MTU is 1518 and the range is between 1518 and bytes.

STEP 4 Click Apply and then click Close. Your changes are saved to the Running Configuration.

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.
