Product Overview

ALFS-3950 Series switch is Fast Ethernet intelligent security access switch for carrier and MAN networks. It supports comprehensive QoS, enhanced VLAN functions (Vlan VPN, Voice Vlan, QinQ, etc), classified bandwidth control, multi link aggregation, intelligent security control, which fulfill the network requirements for carrier network, MAN security access, and so on.

The 3950 series carrier level switch includes ALFS-3950-10C/R/DC, ALFS-3950-26C, ALFS-3950-28C,.The product designed for ipv4 and ipv6 dual stack network. With the abundant ipv6 features, the product can still work for next generation network.

 

Main Features

High adaptability VLAN Features

ALFS-3950 series support 802.1q and port based VLAN, as well as MAC based VLAN. When user move from one port to another, system can still record it as the same user through identified MAC and then keep the same VLAN for the user.

ALFS3950 series has unique Stacking Vlan technology, supporting up to 16 million VLAN, thus can provide one VLAN to each user. The advantages are: most small broadcast domain, with high efficiency; separate data between users on L2 with high security; unique VLAN for each user to identify the user; and VLAN for each user improves the management and operation level.

ALFS-3950 series Vlan VPN (QinQ) technique provide low cost, easy operation, manageable L2 VPN function, and differentiate data packets by its service and area to support more and more business.

Voice Vlan function enables to add IP Phone to voice VLAN to ensure effective QoS..

 

High Reliability

ALFS-3950 series support large number as 2~4 Combo Gigabit uplink ports, which could be designed in various ring protection applications, effectively raised the expansibility and performance of network

ALFS-3950 series support VCT & DDM (Digital Diagnostic Monitoring), help to locate the error places in the link, make it fast to solve relative problems for network management

ALFS-3950 series support STP, RSTP, MSTP based on 802.1D, 802.1W, 802.1S, to avoid loop link and configure abundant backup link in network. 802.3ad port aggregation supported, to add link bandwidth and abundant connection between equipments

With Lightning Protection supported, ALFS-3950 series could ensure the network stability in physical aspect.

 

Enhanced Security

IEEE 802.1X port-based access control ensures all users are authorized before being granted access to the network. User authentication is carried out using any standard-based RADIUS server.

One thousand large number of Access Control Lists (ACLs) can be used to restrict access to sensitive network resources by denying packets and forward by different policies.

The ALFS-3950 series support DHCP snooping, which prevents DHCP attacks and illegal DHCP SERVER by setting trust ports and untrust ports. With DHCP Snooping binding and option82 enabled, it can combine modules like dot1x and ARP, or implement user-access-control independently

The ALFS-3950 product support much more L2 security features such as ARP guard, Anti-ARP scanning, and other ARP and MAC security technology to protect network security and reliability.

 

Comprehensive QoS

ALFS-3950 series switch can classify stream by port, 802.1p, TOS, DSCP, TCP/UDP ports and assign different level of service, supports SWRR/WRR/SP to provide QOS for voice/data/video.

With QinQ, Selective QinQ, Flexible QinQ supported, ALFS-3950 series can also differentiate data packets effectively by its service, vlan and area

 

Abundant Multicast Features

ALFS-3950 series also support MVR (Multicast VLAN Register), selectively allows traffic to cross between different VLANs for bandwidth and security reasons. With MVR Trunk function, which could associate multicast Vlan to trunk port, ALFS-3950 series combine the Vlan data into the same link, saving lots of resources for users.

The ALFS-3950 series could prevent multicast traffic from flooding through IGMP Snooping, while multicast traffic is forwarded to ports associated to multicast devices only

 

Simple management

ALFS-3950 supports Simple Network Management Protocol (SNMP), in-band and out-of-band. Supports Command Line Interface (CLI) and WEB, supports Security IP function to prevent illegal users log in or change the configuration.

As an important feature of carrier network, OAM can help the user to monitor and manage the network across different protocols and equipments.

ALFS-3950 supports Secure Shell (SSH), which will ensure the security of switch management and configuration.

ALFS-3950 can be managed by general network management platform with 3rd management software.

 

Abundant IPv6 Support

The ALFS-3950 series switch supports IPv6 in hardware for maximum performance. As more network devices growing and the need for larger addressing and higher security become critical, the ALFS-3950 series switch will be a right product to meet the requirement. ZHT passed IPv6 form Phase II certificate is the best proof of the application.

The ALFS-3950 series switch also supports DHCPv6, based on IPv6, including DHCPv6 server, client, relay and snooping, etc.

 

Integrated authentication and billing solution

ALFS-3950 support ZHT enhanced 802.1x authentication and billing solution, and authentication by port and MAC address. Working with ZHT DCBI3000 and 802.1x client, it can bill by time/flow, and strict bundle for account, password, IP, MAC, VLAN, port, and switches. It support anti spam, internet time control. With user based dynamic VLAN and bandwidth authorization, it can allocate IP address based on group policy without DHCP server.
