Securing Networks with VLANs

To address these challenges, the use of managed switches like Teltonika Networks' TSW202 and TSW212 is highly advantageous. These switches provide robust network connectivity solutions for various office departments while offering precise control over the entire network infrastructure, extending this control even to endpoint devices.

When integrated with our RUTX50 5G router via Ethernet cables, the TSW212 8-port managed switch significantly expands connectivity options. It facilitates seamless connections to the headquarters' server through SFP ports and links numerous computers within different departments via Gigabit Ethernet ports, ensuring high-throughput data transmission for all endpoints.

The true potential of advanced network configurations becomes accessible with this superior connectivity in place. The TSW212 managed switch, in particular, supports VLAN tagging configurations, enabling each department to operate within separate VLANs. This innovative feature enhances traffic management, effectively creating the impression that each department operates on its dedicated network, all while maintaining complete isolation from one another. Network administrators can centrally manage and monitor this setup, overseeing the entire network infrastructure and data transmission across all departments.

Furthermore, the TSW212 managed switch introduces support for Quality of Service (QoS), allowing prioritization of specific types of network traffic. For instance, critical sales department data can receive priority over less time-sensitive accounting data, ensuring that data from the sales department takes precedence during network congestion, reaching its destination promptly.

With features like QoS and VLAN tagging, network security and seamless data transmission are ensured, leading to optimal efficiency.

The same principle of network prioritization can be applied to remote pick-up centers using the TSW202 managed switch. Here, Point of Sale (POS) terminals can be given higher priority over data-intensive camera feeds, ensuring accurate stock data retrieval at all times.

Moreover, the TSW202's Power over Ethernet Plus (PoE+) capability allows it to power devices like POS systems, cameras, scanners, and IP phones, simplifying network connectivity and reducing cable clutter.

Managed switches excel further in this scenario with features like scheduling, enabling the automatic activation or deactivation of end devices, along with priority adjustments during specific hours. The compatibility with Remote Management System (RMS) facilitates remote execution of these procedures across all devices in a single session, streamlining network management.

In the context of secure and remote communication between headquarters and pick-up centers for data transmission, stock management, and payment information, a VPN-enabled connection is essential. VPNs ensure secure remote access for administrators to interact with headquarters and pick-up center data.

Notably, managed switches like the TSW202 and TSW212 offer value in complex network infrastructures due to their support for multiple protocols, including STP and RSTP. These protocols mitigate network loops and broadcast storms, allowing rapid recovery from network topology changes, thereby ensuring uninterrupted network uptime.
