Description

L3 Managed 48p Gigabit Switch with 4p 10G SPF+ Fiber

LS4840TXB is the smart access switch for carrier’s IP MAN and enterprise networks. Based on the new-generation high-performance hardware, it supports functions such as powerful ACL, flexible QinQ, 1:1 or N:1 VLAN switching, Ethernet OAM, carrier-level QoS and industry-level 10G Ether-ring, ensuring this switch meets application requirements of all kinds among many office sites.

LS4840TXB


    Advanced Hardware Architectureand Industry-Leading Port Intensity

  • 1U box-shaped switch with 48 Gigabit UTP ports, 4 10G SFP+ ports with high-performance ASIC switch chip

    • Carrier-class Ethernet Switches

  • Supports carrier Ethernet ring network protection protocol. The protection switching time is less than 50ms. It also supports simple and effective redundancy protection mechanism such as STP/RSTP/MSTP protocol and dual uplink standby link protection and LACP link aggregation. These functions meet the requirement of carrier grade high reliability.
  • Perfect Ethernet OAM, which can real time monitor the network operating state and rapidly detect and locate the malfunction.
  • Supports strong ACL function. The solution supports L2~L7 data access and control based on the physical port, VLAN IDs, source MAC/IP addresses and protocol port, which provides flexible ways of policy control.
  • Supports various L2 multicast function, including IGMP-Snooping, user fast-leave mechanism and cross VLAN multicast replication function.

    • Carrier QoS Policies

  • Supports complex traffic classification based on VLAN, source MAC/IP addresses, destination MAC/IP addresses, IP protocols, or priorities. It also supports priority remark. These functions provide an effective way for users to optimize their businesses.
  • Provides flexible bandwidth control policies and support a port base or flow-based Committed Access Rate (CAR) and guarantees Layer 3 line-speed forwarding.
  • Every port supports 8 priority queues.
  • Supports multiple queue grooming algorithms such as SP, WRR or SP+WRR.

    • Comprehensive IPv6 Solutions

  • Supports IPv6 based Ping, Traceroute, Telnet, SSH, ACL, meeting the need of IPv6 network equipment management and service control.

    • Comprehensive Security Mechanisms

  • Advanced hardware architecture design, realizing the hierarchical scheduling and protection of the packet. It provides multiple security measures to defend against DOS or TCP attacks; and supports command line authority control based on user levels.
  • Comprehensive Security Certification: Complies with IEEE 802.1x, Radius, BD Tacacs+.
  • Supports the suppression of broadcast, multicast and unknown unicast packet, ensuring the equipment can operate normally in harsh network conditions.
  • Perfect loop detection mechanism.
  • Supports the port isolation in a same VLAN and DHCP-Snooping, IP+MAC+ port binding.

    • Convenient Management and Maintenance

  • Supports multiple management styles such as Console, Telnet, SSH
  • Supports WEB based management. The management is more simple and effective.
  • Supports upload and download of TFTP files.
  • Smart SNMP Network Management Software which supports network element auto-discovery, topology management, equipment configuration management, performance data analysis, and fault management. Network management is simplified and the user gets a new product experience.
