Overview
The LANCOM GS-2426 is designed for medium-sized network infrastructures that require a silent connection for up to 26 end devices and Layer 2 switching. With 24 Gigabit Ethernet ports and two additional combo ports (TP/SFP), this access switch enables flexible, future-proof network expansion – whether via fiber-optics or traditional copper connections. Comprehensive Layer 2 features, such as VLAN support, QoS, and security mechanisms, ensure efficient data prioritization. Thanks to its fanless design, the switch operates silently, making it ideal for noise-sensitive environments such as offices or conference rooms. For easy and intuitive management, users can choose between a web-based GUI and the CLI. The LANCOM Management Cloud (LMC) is perfect for centralized configurations and automated rollouts of all devices in the network.

High Performance and Connectivity
The LANCOM GS-2426 is equipped with 24x 1 Gigabit Ethernet ports and 2x combo ports (TP/SFP). With a data throughput of 52 Gbps on the backplane, the switch offers full performance even under load. The switch therefore forms the high-performance basis for modern network infrastructures.
26 Ports
Provides 24x 1 Gigabit Ethernet ports and 2x combo ports (TP/SFP) for flexible network expansion.
Cloud-Managed LAN and Secure Access
With the LANCOM Management Cloud (LMC) and Cloud-managed LAN, the LANCOM GS-2426 offers quick and easy network integration as well as automatic provision of the configuration across locations with a click of a mouse. Time-consuming individual device and switch port configurations are now a matter of the past. The targeted switch rollout via the LMC enables automatic VLAN assignment to switch ports including practical switch port profiles and therefore “zero-touch” assignment to the devices. Secure Terminal Access provides access to the command line of the LANCOM switch ("CLI tunneling") directly from the LANCOM Management Cloud – encrypted and without leaving the cloud interface. Secure Terminal Access provides expert functions as well as extensive diagnostic and troubleshooting commands for the devices. Some highlights include: “trace” and “ping” commands for quick troubleshooting, access to low-level configuration parameters and detailed statistics of the LCOS SX operating system as well as secure remote access to third-party devices in the local network via the integrated SSH client.
Silent and Reliable Operation
In noise-sensitive environments, this Gigabit access switch expands the network without compromising reliability. Its fanless design with no moving parts ensures silent operation, making it ideal for offices, conference rooms, and other noise-sensitive workspaces. The passive cooling system enhances energy efficiency and eliminates potential points of mechanical failure. This not only extends the device's service life but also maintains a high mean time between failures (MTBF), even under heavy network loads, ensuring consistent network availability. With its combination of silent operation and high reliability, this switch is a future-proof investment for professional IT infrastructures.
Efficient Energy Saving
Thanks to energy-saving functions in accordance with IEEE 802.3az (Energy Efficient Ethernet), the switch automatically disables unused ports and reactivates them instantly – without delay or packet loss – as soon as they are needed again. This effectively conserves valuable energy resources. Cable length detection adjusts the signal strength based on the cable length, reducing power consumption for short cables.
Advanced Layer 2 Switching
Powerful Layer 2 switching with MAC-based data forwarding ensures a stable network infrastructure. Spanning Tree Protocols (STP, RSTP, MSTP) enable a redundant yet loop-free network topology, while Link Aggregation (LACP, IEEE 802.1ax) allows bundling of up to 16 ports per group for improved load balancing. For flexible network segmentation, the Gigabit access switch supports up to 4,096 VLANs, while Voice VLAN prioritizes voice data to ensure optimized Quality of Service (QoS). Additionally, DHCP relay (options 66, 67, 82) simplifies IP address assignment across different network segments.
Interfaces
- ➡️ 24 TP ports 10/100/1000 Mbps
- ➡️ 2 Combo-Ports (TP/SFP) with 10/100/1000 MBit/s (TP) or 100/1000 MBit/s (SFP)
- ➡️ 26 concurrent Ethernet ports in total
- ➡️ RJ45 configuration port for command line access
Security Features
The LANCOM GS-2426 stops rogue clients from gaining unauthorized access to the network. This is ensured by secured access control on all ports as per IEEE 802.1X (port-based, single, multi, and MAC-based) or by ACLs (access control lists). Thanks to secure communication protocols such as SSH, SSL, and SNMPv3, professional remote management of the network is possible. The switch also supports the TACACS+ protocol for authentication, authorization, and accounting. This optimized solution promises maximum security for multi-site network management and monitoring.
Key Security Protocols and Features:
- Secure Shell Protocol (SSH) for secure remote configuration
- Secure Sockets Layer (SSL) to encrypt HTTP connections and enhance browser-based configuration security
- IEEE 802.1X access control on all ports, with RADIUS support for authentication, authorization, and accounting (e.g., MD5 hashing), guest VLAN, and dynamic VLAN assignment
- Private VLAN edge for Layer 2 isolation within the same VLAN ("protected ports")
- Port security for locking MAC addresses to ports and limiting learned MAC addresses
- IP source guard for blocking access from illegal IP addresses on specific ports
- Access control lists (ACLs) for drop or rate limitation of connections based on various criteria (MAC addresses, VLAN ID, IP address, protocol, port, DSCP/IP precedence, TCP/UDP ports, IEEE 802.1p priority, ICMP/IGMP packets, TCP flag)
- RADIUS/TACACS+ for authentication, authorization, and accounting of configuration changes
- Storm Control for multicast/broadcast/unicast storm suppression
- Isolated Group feature to designate certain ports as protected, blocking traffic between members while allowing traffic to non-isolated ports
IPv6 and IPv4 Support
Thanks to its dual-stack implementation, the LANCOM GS-2426 can be used in pure IPv4, pure IPv6, or mixed networks. Numerous applications such as SSL, SSH, Telnet, or TFTP can thus also be run over IPv6 networks. IPv6 features such as stateless autoconfiguration, neighbor device discovery, and MLD snooping round out the IPv6 capabilities.
