ZTE ZXR10 5250-28TM-H Managed L2 Gigabit Ethernet (10/100/1000)

Gigabit Ethernet, 20x RJ45, 4x Combo, 1 x expansion card slot With further development on broadband access, 1000Mbps ports appear more and more on the latest generation access equipment and 1000Mbps to the desktop is becoming the main trend. ZTE ZXR10 5250 series all gigabit intelligent switches are new-generation L2 gigabit switches presented by ZTE Corporation to meet the trend. With high-density Gigabit interfaces, built-in high speed ASIC forwarding chips, full security and reliability related features, efficient QoS priority mechanisms and flexible management patterns, ZXR10 5250 fully satisfies the requirements of metro broadband access and IDC (Internet Data Center). It can act as the access/aggregation switch or IDC TOR.

As the network is converging and the service types in campus network are developing at an ever faster speed, customers are constantly raising higher requirements to the network access devices. Among these requirements, service bearing capability, security, easy-maintenance and energy-efficiency are the top concerns. ZXR10 5250 is the switch equipped with state-of-the-art technologies in these aspects.

Smart VLAN Support

ZXR10 5250 not only supports 1:1 VLAN mapping, but also supports N:1 VLAN mapping. VLAN aggregation thus can thus be implemented at the access layer to increase the efficiency of VLAN utilization.

ZXR10 5250 also supports QinQ and flexible selective QinQ. Network administrator can distinguish user and service effectively and apply different strategies thereafter.

ZXR10 5250 series support Voice VLAN (which means the automatic assignment of dedicated VLAN and Qos strategy to voice equipments), thus enabling the voice traffic to enjoy high priority.

Improve Video Bearing Capabilities

Multicast based technologies like IPTV are important profitable point for service providers. ZXR10 5250 fully supports L2 multicast, including IGMP snooping, Filtering, Proxy and Fastleave, MVR (Multicast VLAN Registration) to facilitate the deployments of these services.

With IPTV control implemented, operators can apply different CAC (channel access control) rules for users with channel packages.

Multicast Qos are also supported to minimize the risks of delay, jitter of the multicast traffic. The time needed to get new user on-line is very short.

IPv6 Features

ZXR10 5250 supports IPv6 features, including Telnet V6, Ping V6, ICMPv6, ND, MLD Snooping, IPV6 ACL and DHCP V6 Snooping to facilitate the deployment of these services.

Enhanced Reliability

ZXR10 5250 series switches support Ethernet smart ring protection function, which goes in line with RFC3619 and ITU.T G.8032 standard. Ethernet smart ring protection can be implemented in both close ring and open ring topology; Multiple instances can be configured in order to realize load-balancing. The switchover time can be kept below 50ms.

ZESS (ZTE Ethernet Smart Switch) and LACP (Link Aggregation Control Protocol) can help guarantee the reliability of the uplink connection.

With technologies like DHCP snooping and IP source guard, user validity can be guaranteed; DAI (dynamic ARP inspection) function can help effectively mitigate the influence caused by ARP attacks.

5250 supports MFF (MAC forced forwarding), L2 separation and L3 inter-communication can be realized;

Network traffic monitoring technologies including mirroring (SPAN and RSPAN) and sFlow are all supported, further enhancing the security of the network.

Enhanced Security

ZXR10 5250's CPU uses control plane security mechanism to classify and control the speed of the protocol messages that CPU needs to process. This mechanism makes sure that the speed of the messages delivered to the protocol stack is within a proper range, which avoids CPU breakdown caused by excessive messages.

For user management, ZXR10 5250 not only supports normal username/password login method, but also supports encrypted login pattern including SSH, further eliminating the risk of username/password revelation.

ZXR10 5250 supports not only ingress ACL, but also egress ACL. User can implement incoming and outgoing traffic classification and speed restriction at the same time. This mechanism enables the customer to greatly simplify configuration and make more refined control in certain scenarios.

For Equipment access control, ZXR10 5250 series switches support local authentication, Tacacs+ authentication and Radius authentication.

5250 supports SSL and can act as a SSL server.

Energy-Saving and Green

ZXR10 5250 series switches fully support IEEE 802.3az, which means it can set the port to idle state dynamically when there's no traffic transmission over the port. In this way, electricity can be saved, and the power consumption of a single port can be reduced by 70%.

ZXR10 5250 supports dynamic fan speed adjustment technology; the rotating speed of the fan can be adjusted according to the internal temperature of the equipment. When the equipment is experiencing relatively high temperature, the rotating speed of the fan will be increased; when the equipment is experiencing relatively low temperature, the rotating speed of the fan will be decreased.

The materials used in making ZXR10 5250 series also go in line with RoHS and WEEE standards, which means minimum pollution and great contribution to global environment.

By using other energy-saving technologies, for example, disabling idle ports and adjusting port power consumption per cable length, ZXR10 5250 series decreases the power consumption for the customer to the utmost extent.

Easy Maintenance

Creative M-Button enables the administrator to obtain the status of equipment, like memory and CPU utilization rate without login onto the 5250. With this feature, the time for administrator to locate the failure cause can be greatly reduced.

ZXR10 5250 supports zero-configuration. When powered on, the equipment will automatically fetch its own software version and images.

ZXR10 5250 supports off-power alarming. Off-power alarm means the equipment can send alarms to designated server if there is a power failure, reporting the equipments halts working because of the power failure. Power failure is a commonly seen error for access equipments, and off-power alarm can help the operation staff make quick judgment and accelerate failure processing.

ZXR10 5250 also supports Ethernet OAM. It not only provides linking fault detection but also provides a method to measure network performances. ZXR10 5250 supports IEEE 802.1ag Connectivity Fault Management (CFM), Ethernet Local Management Interface (E-LMI),IEEE 802.3ah Ethernet OAM discovery, link monitoring, remote fault detection, remote loopback and Y.1731.

ZXR10 5250 supports multiple remote management patterns, including WEBUI, telnet, SNMP, and a USB console interface. The access of equipments can also be controlled by protocols like RADIUS and TACACS+.

Except for traditional management patterns like Telnet and SNMP, ZXR10 5250 also supports USB console and WebUI, further adding the convenience of management.

Two software image files can be stored for backup purpose.
