ZXR10 3900A Series L3 Intelligent Ethernet Switch
Overview ZXR10 3900A series L3 Intelligent Ethernet switches are box-like 1RU-high layer 3 routing switches. ZXR10 3900A series switches provide high density of FE Ethernet ports, complete L2 switching and L3 routing functionalities and enhanced POE/POE+ ability, which enable them to be deployed as access or convergence devices for intelligent campus networks. ZXR10 3900A offers the following switch types: ZXR10 3900A Series L3 Intelligent Ethernet Switch 3928A: 24*FE RJ45 + 2*GE SFP + 1*expansion slot 3928A-PS: 24*FE RJ45 POE/POE+ + 2*GE SFP + 1*expansion slot 3928A-FI: 24*FE SFP + 2*GE SFP + 1*expansion slot 3952A: 48*FE RJ45 + 4*GE SFP The expansion card slot can be equipped with one of following types of cards: ZXR10 3928A ZXR10 3928A-PS ZXR10 3928A-FI ZXR10 3952A 1*GE RJ45&1*GE SFP/2*GE RJ45/2*FE SFP/2*GE SFP Advanced Features ZXR10 3900A has complete L2 switching and L3 routing capabilities; it supports POE, stacking and comprehensive security and reliability related features. Full Service Support ZXR10 3900A series switches support diversified VLAN features, including SuperVLAN, QinQ, selective QinQ, VLAN translation and PVLAN. VLAN translation can be used to separate and distinguish services, while PVLAN can help restrict direct L2 communication between downlink ports. QinQ and selective QinQ enable the administrator to distinguish users and services at the access side effectively. ZXR10 3900A supports routing mechanisms including static routing, RIP, OSPF, IS-IS and BGP.
Multicast-based technologies like video-surveillance and videoconference are becoming more and more popular these days. ZXR10 3900A fully supports L2/L3 multicast, including IGMP snooping, Filtering, Proxy and Fastleave, MVR (Multicast VLAN Registration) and PIM-SM to facilitate the deployment of these services. ZXR10 3900A supports MCE (multi-vrf CE), which means the capability to simulate multiple CEs to reduce the number of CE devices and reduce interface requirement for PE. Each virtual CE is separated from other virtual CE. User isolation and security guarantee can be implemented by multi-vrf CE. Super Extensible Stacking ZXR10 3900A supports super extensible stacking function; a working stack can accept new members or delete existing ones without service interruption. Network extensibility is enhanced as the user can freely increase the capacity of a single logical network node. N+1 redundancy for the master switch helps avoid single-point failure and reduce service breakdown. ZXR10 3900A series switch can provide long-distance (up to 120km) stacking solution. Access interfaces from different member switches can be used to form a logical smart group, fully leveraging the capacity of each single switch member and increasing the flexibility of network design. Intelligent Power over Ethernet All the electrical access interfaces of ZXR10 3928A-PS support POE and POE+, which go in line with 802.3af and 802.3at standards, and are compatible with PD equipment that doesn't support 802.3af and 802.3at. For POE, the power output per single interface can reach 15.4W; For POE+, the power output per single interface can reach 30W. ZXR10 3900A supports assigning time-ranges for POE. During the time when power output is unnecessary, the POE function can be turned off to save energy for the customer. Enhanced Reliability Loop detection allows the switch to detect possible loops without the need to enable STP. With UDLD (uni-directional Link Detection), uni-directional link failure caused by wiring mistake or port failure can be detected. ZXR10 3900A fully supports 802.3ad LACP (link aggregation control protocol) to provide redundancy in case link failure happens, and to broaden bandwidth. When deployed in layer 2 environment, ZESR/ZESR+ (ZTE Ethernet Smart Ring) and ZESS (ZTE Ethernet Smart Switching) can be used to implement fast switchover in case of single point failure. ZXR10 3900A supports both close ring ZESR and open ring ZESR+, which are both very good network redundancy solutions in ring topology networks. ZESS is a very simple yet effective means to realize dual-homing purpose.
Compared with STP, the biggest advantage is that the link will switch and recover quickly when one way is disconnected and the switchover can be done in 50ms. ZESR/ZESR+ supports VLAN load balancing to enable efficient utilization of redundant links. Enhanced Security ZXR10 3900A supports diversified mechanisms to guarantee the security of the network: CPU DDOS (Distributed Denial of Service) protection capability helps the equipment to mitigate the influence caused by attacks. The equipment itself won't be brought down, which ensures the network stability. DAI (Dynamic ARP inspection) function and IP/MAC binding help prevent against DOS (Denial of Service) attacks. 802.1X can be used for authentication purpose. Working together with a policy server, the user control policy can be applied to 3900A after the authentication is done. Bandwidth limit/qos strategy can thus be implemented automatically. Enhanced routing protocol communications, including simple password test and MD5 authentication can be used to prevent the alteration of routing protocol interactions. Traffic mirroring/analyzing functions like RMON (remote monitoring), SPAN (switched port analyzer), RSPAN (remote switched port analyzer) and sflow help analyze real-time network condition.
