DS21554LB+ Datasheet/PDFDS21554LB+ is a digital multi-port switching device designed for digital and inter-network applications. It is based on a tried and tested firmware and hardware design allowing it to offer robust connectivity solutions at the network level. It is a powerful choice for industrial, military, and commercial applications.
The DS21554LB+ can be used in telecommunications, military, industrial, datacom, and multi-layer switching applications. It has the capability to switch a wide range of physical layer services such as serial, Ethernet, and ATM, as well as virtual ports that can provide services such as VoIP, VPN, and MPLS. The device also provides an advanced switching fabric with up to 128 inter-switched ports, allowing it to efficiently route traffic between multiple networks.
The DS21554LB+ is a Layer-2/3 switch with support for various protocols such as Spanning Tree Protocol (STP), Open Shortest Path First (OSPF), and Multi-Protocol Label Switching (MPLS). It supports a variety of packet switching algorithms and services such as port forwarding, IP routing, rate limiting, and quality of service (QoS).
The switch provides a total of 24 ports, with 8 Gigabit Ethernet (GigE) ports and 16 10/100M Ethernet ports. The ports are capable of forwarding IPv4, IPv6, and other Ethernet frame types such as ARP, RARP, and 802.1Q. The device is compliant with the appropriate industry standards, including IEEE 802.3, 802.3u, and 802.3z. It also supports a wide range of Layer-2 switching functions such as VLANs, link aggregation, and port mirroring. The DS21554LB+ also features four levels of QoS classification, including LAN port-based, VLAN-based, and IP and MAC address-based.
The DS21554LB+ allows for simplified setup and configuration with its web-based GUI, SSH access, and out-of-band management through serial port or Telnet. The device also supports the ability to store configurations in an embedded flash memory, simplifying setup and deployment of multiple devices. The switch is compliant with the most common network management protocols such as Simple Network Management Protocol (SNMP) and Embedded Web Access (EWA).
The DS21554LB+ is easy to use, configure, and manage, making it an ideal choice for businesses who require a reliable and cost-effective switching solution.
