ZXR10 3900A/3200A Series L3 Intelligent Ethernet Switches

Oriented to the access layers of the enterprise networks and broadband IP MANs, ZXR10 3900A/3200A series middle/low-end L3 intelligent Ethernet switches provide a high density of Ethernet ports, making them most suitable to be used as user-side access devices for intelligent community, office buildings, hotels, college campuses and enterprise networks (government networks), or as convergence devices for small networks to provide users with high-speed, efficient and high cost-effective convergence solution.

Product Positioning

Features and Specifications

• Carrier-class reliability
  Providing redundancy on the physical layer, supporting power redundancy and hot-swappable boards; providing redundancy on the protocol layer, and supporting the protocols such as LACP, VRRP, and routing load sharing.
• Full Wire-speed forwarding and filtering
  ASIC hardware switching is used to ensure the wire speed running of L2, L3 and IPv6 switching. ASIC hardware filtering is used to ensure packets filtering on L2-L7 and wire speed running of L2-L4 ACL.
• SES (Super Extendable Stacking)
  SES can integrate the resources of several switches to expand the overall switching capacity and port density, and in this way, several switches can be put together as one super switch. Compared with the stacking technology in the past, SES is essentially an extendable stacking technology. Super Switch, which uses SES stacking technology, is not independent switch units essentially, but a distributed switch (Chassis) system.
• IPv6 Ready and POE Enhancement
  The 3900A series products support various IPV6 protocol technologies, including IPV4 and IPV6 dual protocol stacks, 6to4 tunnel . 3928A-PS supports POE,IEEE 802.3af, power <30W every port. Max support port number 24.
• Interfaces
  ZXR10 3900A series middle/low-end L3 intelligent Ethernet switches provide a high density of Ethernet ports.

Architecture and Key Components

By using latest and leading ASIC hardware forwarding technology in the industry, most forwarding features are performed by hardware, which ensures the port with wire-speed forwarding capability. Within the ASIC, L2 switching, IPv4 routing, IPv6 routing and the flow filtering of L2-L7 are performed at wire-speed.

The software system of the ZXR10 3900A/3200A series routing switches take the ZXROS distributed large-scale routing platform software as its core. As the result of our long years’ efforts in data products, this platform software also serves the ZXR10 series high-end routers and switches. It provides a great variety of protocol stacks required for L2, L3, MPLS, and IPv6, and provides unified interfaces to its lower layer. 

The drivers of the ASIC are used to connect the ZXROS and the actual ASIC execution entities.

The NM and Operation & Maintenance module provides the user management interface for the switch. This module allows users to manage and operate with the switch through a wide variety of means such as 232 interface, Telnet, SSH, and SNMP.

ZXR10 3900A/3200A series has been deployed in commercial networks.
