H3C S3600-28P-SI L3 Power over Ethernet (PoE) Black

S3600-28P-SI, 28-port, Fast Ethernet, 12.8Gb/s, Flow Control H3C S3600 Series Ethernet Switches are a new generation of premier multi-layer switches that entirely fulfill the enterprise requirement for design and implementation of a unified, highly resilient network. One of the most important and innovative highlights of the S3600 Series Ethernet Switches is the IRF (Intelligent Resilient Framework) technology which offers the highly efficient advantage of stackable technology. IRF enables network managers to build adaptable networks with high reliability, scalability and easy management. “Pay as you go” is the slogan of the S3600 Series Ethernet Switches.

Full wire-speed, multi-layer switching
- The S3600 Series offer L2/L3 wire-speed switching capability for all ports. The system offers 4 GE ports to meet the requirement of a single piece of equipment for multiple Gigabit uplinks and for access to the Gigabit server, thereby greatly increasing savings on equipment investment.
- The hardware supports L3 wire-speed switching, and is able to identify and process the application traffic flows from L2~L4.
- All ports have an independent data packet filter, and distinguish specific application flows for different management and control.

IRF Technology
Intelligent Resilient Framework (IRF) is an innovative resilient network technology that allows enterprise customers to design and implement Fast Ethernet core and aggregation that are adaptable, providing exceptional reliability, scalability and easy management. With IRF technology, the S3600 Series switches can be interconnected together to behave as a single logical switching entity called a Distributed Fabric. From management and configuration perspectives, the Fabric appears as a single device, while from a performance perspective, each switch in the Distributed Fabric can make its own forwarding decisions, both at Layer 2 and Layer 3 for traffic that appears on its ports.

The IRF technology provides: DDM (Distributed Device Management), DRR (Distributed Resilient Routing) and DLA (Distributed Link Aggregation).

- Distributed Device Management (DDM)
Distributed Device Management is the control system for IRF technology, responsible for distributing management and control information across the IRF Distributed Fabric.
- Distributed Resilient Routing (DRR)
Distributed Resilient Routing, provided by Enhanced Image, is an advanced routing implementation that allows multiple interconnected switches in an IRF Distributed Fabric to behave as a single active routing entity.
- Distributed Link Aggregation (DLA)
Distributed Link Aggregation, provided by Enhanced Image, allows networks and IRF Distributed Fabrics to be coordinated with switches at the edge of the network. DLA guarantees high levels of resilience since failure in one of the members of the Aggregated Link results in automatic redistribution of traffic across the remaining links.

Excellent PoE (Power over Ethernet) Supply Function
The S3600 Series Switches support PoE function for the LAN switching infrastructure, which provides power over a copper Ethernet cable to an endpoint (Powered Device).
- The S3600 Series switches provide up to 48 simultaneous full-powered PoE ports at 15.4W for maximum powered-device support, such as IP telephony and wireless LAN deployments. As PSE (Power Sourcing Equipment) devices, all S3600 series Switches are 802.3af compliant PoE switches.
- With PoE and Voice VLAN technology, these innovative switches can provide the perfect solution for a converged voice and data network.

High reliability
- The S3600 Series supports STP/RSTP/ MSTP, greatly improving redundant back-up for links and fault tolerance capability, so the network can run with high levels of stability.
- The S3600 Series supports the optional RPS (Redundant Power Supply, provided by Enhanced Image), thus improving the fault tolerance capability and normal network operation duration.
- The S3600 Series supports VRRP (provided by Enhanced Image), and can build a VRRP back-up group with other L3 switches. In this way, a redundant route topological structure can be built so that when a fault occurs in guaranteeing communication continuity and reliability, network stability is maintained.
- The S3600 Series supports the VRRP backup group port tracking function. As long as this function is enabled, customers can elect to track the link state of the master’s uplink port and decrease the priority of the switch when the port fails. This in turn triggers the new master to be determined in the backup group.
- The S3600 Series supports ECMP (Equal Cost Multi-path Protocol, provided by Enhanced Image) routing, which can be used for load balance and routing redundancy.

Abundant QoS policies
- The S3600 Series supports L2~L4 complex flow classification based on source MAC address、destination MAC address、VLAN、source IP address、destination IP address, ports and protocols.
- The S3600 Series supports flexible queue scheduling algorithms, which can be set on the basis of port and queue at the same time. They support Strict Priority (SP), Weighted Round Robin(WRR), Weighted Fair Queuing (WFQ), SP+WRR, and SP+WFQ; 8 priority queues and 2 drop precedence; WRED congestion avoidance algorithm and port traffic shaping.
- The S3600 Series supports Committed Access Rate (CAR) and limits the traffic speed at 64Kbit/s granularity.
- The S3600 Series can configure the Priority for Protocol Packets. Each protocol packet has its own priority. Customers can modify the priority of the protocol packet with the help of relevant QoS commands.

Flexible security control policies
- The S3600 Series supports ARP detection to guard against ARP spoofing launching by hackers or attackers. According to the ARP detection function, the switches check the validity of the ARP packets using the DHCP-Snooping table or the manually configured IP bonding table. You can also set trusted ports. ARP packets coming from the trusted ports will not be checked, while those from other ports will be checked through the DHCP-Snooping table or the manually configured IP binding table.
- The S3600 Series supports 802.1x authentication to identify users who attempt to access the network. With the 802.1x client version checking function enabled on a switch, the switch checks the version and validity of the 802.1x client running on supplicant systems to prevent those using earlier versions of the 802.1x client or illegal clients from logging in.
- The S3600 Series supports Centralized MAC address authentication. It controls accesses to a network through ports and MAC addresses. This kind of authentication requires no client software. When operating in centralized MAC address authentication mode, a switch begins to authenticate the user if it detects a new user MAC address. Additionally, the S3600 Series can perform 802.1x authentication and MAC address-based authentication simultaneously.
- The S3600 Series supports the Guest VLAN function. This function enables supplicant systems that are not authenticated to access specific resources and thus perform the corresponding operations, such as obtaining the 802.1x client, upgrading the client, or obtaining other upgrading programs.
- The S3600 Series can also prevent unauthorized access to the network by binding any combination of MAC, IP and PORT.

Diversified System Configuration and management modes
- The S3600 Series supports Simple Network Management Protocol (SNMP) v1/v2/v3 and RMON (Remote Monitoring) v1, 1/2/3/9 groups of MIBs. These can be managed by a general network management platform such as OpenView, and H3C iMC network management system.
- The S3600 Series supports Command Line Interface (CLI), Web based network management, modem dial-up and TELNET, all of which make the equipment management more convenient.
- The S3600 Series supports HGMP V2 cluster management. After enabling HGMP V2, the network administrator can manage several member switches through one command switch and only the command switch needs a public network IP address. This can add up to large public IP address savings and also contributes significantly to more effective network management.

Abundant System Maintenance and debugging methods
- The S3600 Series supports DLDP (Device Link Detection Protocol). DLDP can detect the link status of the optical fiber cable or copper twisted pair. If DLDP finds a unidirectional link, it disables the related port automatically or informs users to disable it manually depending on the specific configuration, to avoid potential network problems.
- The S3600 Series supports Loopback detection on ports. After users enable loopback detection for Ethernet ports, the switch will monitor whether the ports have loopback on a regular basis. If the switch detects loopback for a particular port, then it will put that port under control.
- The S3600 Series supports VCT (Virtual Cable Test), convenient for troubleshooting. Customers can start the virtual cable test (VCT) to make the system test the cable connected to the current electrical Ethernet port. The test items include: whether a short or open circuit exists in the Rx/Tx direction of the cable, and the length of the cable in normal status or the length from the port to the fault point of the cable.
