Description

Key Features at a Glance

  • Port Configuration: 24 Gigabit Ethernet ports and 4 SFP slots for flexible copper and fiber connections.
  • L2+ Management: Extensive Layer 2 and Layer 3 functionality, including VLAN, QoS, static and dynamic routing.
  • Industrial Protocols: Support for Profinet Class B (optional) and EtherNet/IP for seamless integration into automation environments.
  • Dynamic Routing: BGP, OSPF v2, RIP v1/v2, and EIGRP for scalable network topologies.
  • Security: 802.1x, MAC filtering, RADIUS/TACACS+, and VLAN segmentation to secure network access.
  • High Performance: Non-blocking architecture with Jumbo Frame support up to 10,000 bytes for efficient data traffic.

Performance and Throughput

The switch architecture ensures all ports can operate simultaneously at full Gigabit speed without bottlenecks, achieved through a powerful hardware platform with a non-blocking backplane design.

  • Forwarding Rate: 83.33 Mpps
  • Jumbo Frames: up to 10,000 bytes
  • Packet Buffer: 512 KB
  • MAC Address Table: 8,000 entries

System and Management

The SWM281 runs on Teltonika’s proprietary TSWOS operating system, based on OpenWrt, providing a flexible, Linux-based environment. A Realtek single-core 500 MHz processor, 128 MB DDR3 RAM, and 16 MB serial flash memory ensure reliable operation.

  • Firmware Update: via file, server verification, FOTA, and RMS
  • Configuration Management: profiles, backup, and retention of settings during FW updates
  • Diagnostic Tools: cable diagnostics, Ping, Traceroute, Nslookup
  • Development Environment: SDK package with build environment, support for Busybox shell, Lua, C, C++
  • Package Manager: for installing additional software

Security and Access Control

Comprehensive security mechanisms protect the network from unauthorized access. Authentication is handled via PAM with preshared key, RADIUS, and TACACS+, complemented by IP and login attempt blocking.

  • 802.1x: port-based network access control (client and server)
  • MAC Filtering: allows specific MAC addresses, ignores or disables ports for unauthorized addresses
  • VLAN Segmentation: port-based VLAN separation for enhanced security

Industrial Protocols and Redundancy

The SWM281 integrates seamlessly into industrial automation environments. It supports Profinet Class B (available as an option) and EtherNet/IP for communication with PLCs and other field devices. Media Redundancy Protocol (MRP) with client and manager roles ensures network failover protection.

  • Dynamic Routing: BGP, OSPF v2, RIP v1/v2, EIGRP
  • Static Routing: IPv4 and IPv6
  • MRP: client and manager roles for ring redundancy
  • Profinet: Class B compliance (optional)
  • EtherNet/IP: Yes
