5250 supports comprehensive features to facilitate the deployment of unicast/multicast services. Traffic separation/Qos/network resilience/security related requirements can all be met. 5250 is also strong in its easy-maintenance and energy-saving features, making large-scale deployment both efficient and environmental-friendly.\n\nInnovative Features\n\nAs 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. 5250 is the switch equipped with state-of-the-art technologies in these aspects. Customers can choose between the three sub-series of 5250 to find the product that best meet their demand while saving investment.\n\nFull L2 features\n\n- 5250 supports IEEE 802.1d spanning tree, IEEE 802.1w fast spanning tree and 802.1s multiple spanning tree for L2 loop-free purpose. 5250 supports IEEE 802.3ad link aggregation; at most 8 ports can reside in one link aggregation group and 5250 supports 15 link aggregation groups.\n- 5250 supports Jumbo frame function; frame with a maximum size of 10240 is supported\n- 5250 supports IEEE 802.1q. 4096 VLAN is supported while the VLAN 1-4094 can be used as service VLAN (4094 active VLAN at most)\n- The VLAN can be assigned based on port or MAC address\n- 5250 not only supports 1:1 VLAN mapping, but also supports N: 1 VLAN mapping. VLAN aggregation can thus be implemented at the access layer to increase the efficiency of VLAN utilization\n- 5250 also supports QinQ and flexible selective QinQ. Network administrator can distinguish users and services effectively and apply different strategies thereafter\n- 5250 supports GVRP thus easy-configuration is provided in case of installing multiple Ethernet switches\n- 5250 supports Voice VLAN (which means the automatic assignment of dedicated VLAN and Qos strategy to voice equipment), thus enabling the voice traffic to enjoy higher priority\n\nImprove Video Bearing Capabilities\n\nMulticast-based technologies like video-surveillance, videoconference and IPTV are becoming more and more popular these days. 5250 fully supports L2 multicast, including IGMP v1/v2/v3 snooping, Filtering, Proxy and Fastleave, MVR (Multicast VLAN Registration) to facilitate the deployment of these services.\n5250 also supports administratively scoped multicast to implement refined control to multicast applications.\n\nIPv6 Features\n\n5250 supports many IPv6 features, including IPV6/IPV4 dual protocol stacking, Telnet v6, Ping V6, ND, MLD Snooping, IPV6 ACL and DHCP V6 Snooping to facilitate the deployment of these services (5250-L doesn't support).\n\nQos\n\n5250 supports full Qos related features including traffic classification, priority marking/re-marking, queue scheduling, congestion management and traffic speed limiting\n\nIEEE 802.3x is supported for traffic control purpose\n\nTraffic classification/priority marking can be done based on VLAN id (IEEE 802.1p), physical interface, TCP/UDP port number, and also on COS and TOS value\n\n8 priority queues are supported on each interface of 5250. 5250's queue scheduling means include SP (strict priority), WRR (weighted round robin).\n\n5250 supports traffic speed limiting on both ingress interfaces and egress interfaces\n\nBroadcast/multicast and unknown unicast suppression are also supported to minimize the possibility of network storm\n\nEnhanced Security\n\n5250'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 switch's protocol stack is within a proper range, which avoids CPU breakdown caused by excessive messages.\n\nFor user management, 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\n\n5250 supports DHCP snooping and can implement DAI (dynamic ARP inspection) and IP source guard to mitigate the effect of any possible network attack\n\n5250 supports not only ingress ACL but also egress ACL. ACL can be configured on target/source IP address and target/source TCP/UDP port number. VLAN based ACL is also supported.\n\nUser 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.\n\nThe privilege of user groups can be assigned so that different user groups can have access to different command sets. 5250 can read the user privilege info from AAA (Authentication, Authorization and Accounting) server and then implement privilege controls on different users.\n\nThe network administrator can have better insight into certain network traffic by implementing SPAN (Switched Port Analyzer) or RSPAN (remote SPAN) and studying the captured traffic.\n\nBesides, the network administrator can implement the management of user, user group and role. By arranging correct relationships between user, user group and role, security control mechanism is provided. Via login Authentication, it prevents illegal users from accessing the system. By authorizing operation, it offers security mechanism to administrator?s operation.\n\nEnergy-Saving and Green\n\n5250 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 up to 70%.\n\n5250 supports dynamic fan speed adjustment, 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.\n\nThe materials used in making 5250 also go in line with RoHS and WEEE standard which means minimum pollution and great contribution to global environment\n\nBy using other energy-saving technologies, for example, disabling idle ports and adjusting port power consumption per cable length, 5250 decreases the power consumption for the customer to the utmost extent\n\nEasy Maintenance\n\n5250 supports multiple remote management patterns, including local CLI (command line interface), WEBUI, telnet, SSHv2, SNMPv1/v2/v3, GUI and a USB console interface.\n\n5250 supports EAP (extensible authentication protocol), MAC-based Authentication, and the access of 5250 can also be controlled by protocols like 802.1x, RADIUS and TACACS+\n\n5250 can realize local and remote authorization in order to ensure the safety of operation. In addition to that 5250 provides NBI (North-bound interface) to provide interconnection integration.\n\nFTP and TFTP are supported to let user download software or configuration file from the web. 5250 has 256MB flash memory which means multiple copies of software and configurations can be kept on the switch.\n\n5250 supports RMON; administrator can define events of their interest and can have knowledge of these events in case these events happen.\n\nCreative 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 it takes the administrator to locate the cause of failure can be greatly reduced.\n\n5250 supports zero-configuration and When powered on the equipment can automatically fetch its own software version and images.\n\n5250 supports off-power alarming. Off-power alarm means the equipment can send alarms to designated server if there is a power failure, reporting the equipment stops working because of the power failure. Power failure is a commonly seen error for access equipment, and the off-power alarm can help the operation staff make a quick assessment to accelerate failure processing.\n\n5250 also supports Ethernet OAM (only 5250-H supports). It not only provides fault detection methods but also provides a method to measure network performance. Additionally, it 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.\n\n5250 supports NTP (Network Time Protocol) and it can synchronize its clock with the main clock in the network\n\n5250 supports LLDP and LLDP-MED to communicate with other equipment in the network\n\n5250 is highly reliable, with a MTBF>200,000 hours
