Intelligent flexible architecture

The H3C S5120S-EI series switches support IRF2 (second-generation intelligent elastic architecture) technology, which connects multiple physical devices to each other and makes them virtual as a logical device. That is, users can treat these multiple devices as one. A single device is managed and used. In addition, the H3C S5120S-EI series switches enable the IRF2 virtualization feature on the common service port. The service port can work in the 2.5G working mode to provide higher stacking bandwidth and improve device forwarding performance and reliability. IRF2 can bring the following benefits to users:

* After simplifying the management of the IRF architecture, you can connect to any port of any device to log in to a unified logical device, and manage the entire intelligent elastic system and all member devices in the system by configuring a single device. They are configured and managed separately without physically connecting to each member device.

* The various control protocols running in the logical device formed by the simplified service IRF are also operated as a single device. For example, the routing protocol is uniformly calculated as a single device, and the application of the cross-device link aggregation technology can replace the original one. The spanning tree protocol eliminates the interaction of a large number of protocol packets between devices, simplifies network operations, and shortens the convergence time during network turbulence.

* Flexible expansion It can be flexibly expanded according to user needs to ensure user investment. The newly added device can be hot swapped when it joins or leaves the IRF architecture, and does not affect the normal operation of other devices.

* High reliability The high reliability of IRF is reflected in three aspects: link, device and protocol. The physical port of the member device supports the aggregation function. The physical connection between the IRF system and the upper and lower devices also supports the aggregation function. This improves the reliability of the link through multi-link backup. The IRF system consists of multiple member devices. Once the master device fails, the system will automatically elect a new master to ensure that the service through the system is not interrupted, thus achieving device-level 1:N backup; the IRF system will have real-time protocol hot backup function responsible for the configuration information of the protocol. Back up to all other member devices to achieve 1:N protocol reliability.

* High performance For high-end switches, performance and port density increases are limited by the hardware architecture. The performance and port density of the IRF system is the sum of the performance and port count of all devices within the IRF. Therefore, the IRF technology can easily increase the switching capacity of the device and the density of the user port by several times, thereby greatly improving the performance of the device.

Complete security control strategy

The H3C S5120S-EI series switches support the innovative single-port multi-authentication triple function. In the network environment where the client is diverse, the access authentication modes supported by different clients are different. For example, some clients can only perform MAC addresses. Authentication (such as printer terminals), some user hosts perform 802.1X authentication, and some user hosts only want to perform Portal authentication through Web access. To flexibly adapt to the multi-authentication requirements of the network environment, the S5120S-EI series switches support the single-port multi-authentication unified deployment mode, so that users can select any suitable authentication mechanism for authentication, and only need one way. Authentication can be achieved by authentication. The client provides the Guest Vlan function, so that the authorized access terminal can only access specific resources, and adopt corresponding policies, such as obtaining an 802.1x client, upgrading the client, or obtaining other upgrade programs. Support for the Secure Shell V2 (SSH V2) feature provides secure information assurance and powerful authentication to protect Ethernet switches from attacks such as IP address spoofing, clear text password interception, and more.

The ARP attack and the ARP virus are the first major threats to the security of the local area network. The H3C S5120S-EI series switches support the ARP defense function, such as ARP detection, and check the validity of the ARP packets. Avoid a large number of ARP packets impacting the CPU and so on.

The H3C S5120S-EI series switches support EAD (Terminal Admission Control). The background system can integrate terminal security measures such as terminal anti-virus and patch repair with network security measures such as network access control and access control to form a coordinated security. The system, through the inspection, isolation, repair, management and monitoring of the network access terminal, makes the entire network become passive defense for active defense, change single point defense for comprehensive defense, and decentralized management for centralized policy management, improving network to virus The overall defense capabilities of emerging security threats such as worms.

Rich QoS strategy

The H3C S5120S-EI series switches support L2 (Layer 2)~L4 (Layer 4) packet filtering, providing source MAC address, destination MAC address, source IP address, destination IP address, TCP/UDP port number, protocol type, and VLAN traffic classification. Provide flexible pair scheduling algorithm, which can be set based on ports and queues at the same time, and supports SP, WRR, SP+WRR modes. Supports port mirroring in both directions. It is used to monitor packets on the specified port and copy the packets on the port to the monitoring port for network detection and troubleshooting.

Excellent management

The H3C S5120S-EI series switches support SNMPv1/v2/v3 (Simple Network Management Protocol) and support common network management platforms such as Open View and iMC intelligent management center. Support CLI command line, Web network management, TELNET, HGMPv2 cluster management, make device management more convenient, and support encryption methods such as SSH2.0, making management more secure.

The H3C S5120S-EI series switches support VLANs based on MAC addresses, which solves the problem of intelligent and flexible management of mobile office. The combination of the unique global and VLAN-based ACL policies simplifies user configuration and greatly saves hardware resources.
