The built-in power module can provide 124 W PoE power, which ensures full PoE power on 8 ports in compliance in 802.3af or on 4 ports in compliance with 802.3at. The switch cannot connect to an RPS power supply.The S2720-28TP-PWR-EI and S2720-52TP-PWR-EI has a built-in power module and does not support pluggable power modules. The built-in power module can provide 370 W PoE power, which ensures full PoE power on 24 ports in compliance in 802.3af or on 12 ports in compliance with 802.3at. The switch cannot connect to an RPS power supply.Non-PoE Power Supply ConfigurationThe S2720-EI series non-PoE switches have a single internal power module and do not support pluggable power modules. Product Features and HighlightsFlexible Ethernet Networking●In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the S2720-EI supports Huawei-developed Smart Ethernet Protection (SEP) technology and the latest Ethernet Ring Protection Switching (ERPS) standard. SEP is a ring protection protocol specific to the Ethernet link layer, and applies to various ring network topologies, such as open ring topology, closed ring topology, and cascading ring topology. This protocol is reliable, easy to maintain, and implements fast protection switching within 50 ms. ERPS is defined in ITU-T G.8032. It implements millisecond-level protection switching based on traditional Ethernet MAC and bridging functions.●The S2720-EI supports Smart Link, which implements backup of uplinks. One S2720-EI switch can connect to multiple aggregation switches through multiple links, significantly improving reliability of access devices.●The S2720-EI supports Ethernet OAM (IEEE 802.3ah/802.1ag) to fast-detect link faults.Diversified security control●The S2720-EI supports 802.1x authentication, MAC address authentication, and combined authentication on a per port basis and implements dynamic policy delivery (VLAN, QoS, and ACL) to users.●The S2720-EI collects and maintains information about access users, such as IP addresses, MAC addresses, IP address leases, VLAN IDs, and interface numbers in a DHCP snooping binding table. In this way, IP addresses and access interfaces of DHCP users can be tracked. You can specify DHCP snooping trusted and untrusted ports to ensure that users connect only to the authorized DHCP server.●The S2720-EI supports strict ARP learning. This feature prevents ARP spoofing attackers from exhausting ARP entries so that users can connect to the Internet normally.Easy maintenance●The S2720-EI can be managed and maintained using Simple Network Management Protocol (SNMP) V1, V2, and V3, Command Line Interface (CLI), web-based network management system, or Secure Shell (SSH) V2.0.●The S2720-EI supports Super Virtual Fabric (SVF), which virtualizes the "Core/aggregation + Access switch + AP" structure into a logical device. The S2720-EI enables the simplest network management solution in the industry. It allows plug-and-play access switches and APs. In addition, the S2720-EI supports service configuration templates. The templates are configured on core devices and automatically delivered to access devices, enabling centralized control, simplified service configuration, and flexible configuration modification. The S2720-EI functions as a client in an SVF system●The S2720-EI can use the GARP VLAN Registration Protocol (GVRP) to implement dynamic distribution, registration, and propagation of VLAN attributes. GVRP reduces manual configuration workload and ensures correct configuration. Additionally, the S2720-EI supports MUX VLAN, which involves a principal VLAN and multiple subordinate VLANs. Subordinate VLANs are classified into group VLANs and separate VLANs. Ports in the principal VLAN can communicate with ports in subordinate VLANs. Ports in a subordinate group VLAN can communicate with each other, whereas ports in a subordinate separate VLAN can communicate only with ports in the principal VLAN. The S2720-EI also supports VLAN Central Management Protocol (VCMP) and VLAN-Based Spanning Tree (VBST) protocol.iStack●The S2720-EI supports intelligent stack (iStack). This technology combines multiple switches into a logical switch. Member switches in a stack implement redundancy backup to improve device reliability and use inter-device link aggregation to improve link reliability. iStack provides high network scalability. You can increase ports, bandwidth, and processing capacity of a stack by simply adding member switches to the stack. iStack also simplifies device configuration and management. After a stack is set up, multiple physical switches are virtualized into one logical device. You can log in to any member switch in the stack to manage all the member switches in the stack.Excellent network traffic analysis●The S2720-EI supports the sFlow function. It uses a method defined in the sFlow standard to sample traffic passing through it and sends sampled traffic to the collector in real time. The collected traffic statistics are used to generate statistical reports, helping enterprises maintain their networks.Product SpecificationsFunctions and FeaturesThe following table lists the functions and features available on the S2720-EI.MAC address table 16K MAC address entriesMAC address learning and agingStatic, dynamic, and blackhole MAC address entriesInterface-based MAC learning limitingVLAN 4K active VLANsGuest VLAN and voice VLANGVRPMUX VLANVLAN assignment based on MAC addresses, protocols, IP subnets, policies, and interfaces1:1 and N:1 VLAN mappingEthernet loop protection RRPP ring topology and RRPP multi-instanceSmart Link tree topology and Smart Link multi-instance, providing millisecond-level protectionswitchoverSEPERPS (G.8032)STP (IEEE 802.1d), RSTP (IEEE 802.1w), and MSTP (IEEE 802.1s)Reliability EFM OAM (802.3ah)CFM OAM (802.1ag)ITU-Y.1731DLDPLACPIP routing Static route, RIP, RIPng, OSPFIPv6 Neighbor Discovery (ND)Path MTU (PMTU)IPv6 ping, IPv6 tracert, and IPv6 TelnetMulticast IGMPv1/v2/v3 snoopingControllable multicastInterface-based multicast traffic statisticsMLDv1/v2 snooping (Multicast Listener Discovery snooping)QoS/ACL Rate limiting by an interfaceEight queues on each interfaceWRR, DRR, SP, WRR+SP, and DRR+SP queue scheduling algorithmsRe-marking of the 802.1p priority and DSCP priorityRate limiting in each queue and traffic shaping on interfacesSecurity Port isolation, port security, and sticky MACMFFBlackhole MAC address entriesLimit on the number of learned MAC addressesIEEE 802.1x authentication and limit on the number of users on an interfaceAAA authentication, RADIUS authentication, HWTACACS authentication, and NACSSH V2.0Hypertext Transfer Protocol Secure (HTTPS)CPU defenseBlacklist and whitelistDHCP relay, DHCP server, DHCP snoopingDHCPv6 relay, DHCPv6 server, DHCPv6 snoopingSuper Virtual Fabric (SVF) Working as an SVF client that is plug-and-play with zero configurationAutomatically loading the system software package and patches of clients One-clickand automatic delivery of service configurationsSupports independent running clientManagement and maintenance iStackVirtual Cable Test (VCT)Remote configuration and maintenance using Telnet SNMPv1/v2c/v3RMONeSight and web-based NMSHTTPSLLDP/LLDP-MEDSystem logs and multi-level alarms802.3az EEEInteroperability Supports VBST (Compatible with PVST/PVST+/RPVST)Supports LNP (Similar to DTP)Supports VCMP (Similar to VTP)Hardware SpecificationsThe following table lists the S2720-EI hardware specifications.Memory (RAM) 512 MBFlash memory Hardware 512MB, customer available 240MB Switching capacity 52-Port: 336 Gbps, others: 68 Gbps Forwarding performance ●S2720-12TP-EI: 12.6Mpps●S2720-12TP-PWR-EI: 12.6Mpps●S2720-28TP-PWR-EI-L: 20.4Mpps●S2720-28TP-EI: 20.4Mpps●S2720-28TP-PWR-EI: 20.4Mpps●S2720-52TP-EI: 34.8Mpps●S2720-52TP-PWR-EI: 34.8MppsMean Time Between Failures (MTBF), years ●S2720-12TP-EI: 23.8●S2720-12TP-PWR-EI: 23.8●S2720-28TP-PWR-EI-L: 42●S2720-28TP-EI: 49●S2720-28TP-PWR-EI: 40●S2720-52TP-EI: 31●S2720-52TP-PWR-EI: 38Mean Time To Repair (MTTR), hours 2Availability > 0.99999Surge protection Service port protection Common mode: ±7 kVPower supply port protection ●DC: ±1 kV in differential mode;
