S5500-SI series hardware supports IPv4/IPv6 dual stack, where IPv4 supports static routing and RIP protocol, and IPv6 supports static routing and RIPng protocol. At the same time, it supports IPv6 ACL and network management, and realizes the smooth upgrade from IPv4 to IPv6.
H3C S55 10-SI switch adopts patented technology, which allows the switch to stack up to 16 devices by using special interconnection cables, and supports mixed stacking of devices with different ports. It has the advantages of plug and play and single IP management. At the same time, it greatly reduces the cost of system expansion and protects the investment of users. Support PoE (power over Ethernet) technology, connected devices (such as IP phone, wireless AP, etc.). ) are all remotely powered by Ethernet, so there is no need to deploy a separate power supply system for the equipment at the use site, which can greatly reduce the wiring and management costs of deploying terminal equipment. Support voice VLAN technology, the switch identifies the voice traffic of the port, adds the corresponding access port for voice VLAN (dedicated voice VLAN), provides a dedicated channel for voice traffic, and automatically issues priority rules to ensure the priority transmission of voice traffic and ensure the call quality. At the same time, by setting the security features of voice VLAN, only voice traffic is allowed to pass, which can effectively prevent the impact of sudden data traffic in voice VLAN on voice traffic.
S5500-SI series switches can provide a complete voice equipment management scheme by supporting the combination of POE and voice Vlan technology, and solve the problems of intelligent detection, power supply and priority adjustment of a large number of IP phones. H3C S5500-SI series switches support EAD (Terminal Access Control) function. Through the background system, terminal security measures such as terminal antivirus and patch repair can be integrated with network security measures such as network access control and access authority control into a linked security system. Through the inspection, isolation, repair, management and monitoring of network access terminals, the whole network has changed from passive defense to active defense, from single-point defense to comprehensive defense, and from decentralized management to centralized policy management, and has been improved.
H3C S5500-SI series switches provide 802. 1x authentication for users trying to access the network. You can verify the version and validity of the 802. 1x client on the switch to prevent illegal users from logging into the network. An authentication method, which supports centralized MAC address authentication, can control users' network access rights according to ports and MAC addresses. It does not require users to install any client software, and can run both 802. 1x authentication and authentication based on MAC address. Provide Guest Vlan function, so that authorized access terminals can only access specific resources, and take corresponding strategies, such as acquiring 802. 1x clients, upgrading clients or acquiring other upgrading programs. Supporting Secure Shell V2(SSH V2) can provide secure information guarantee and powerful authentication function, and protect Ethernet switches from IP address fraud and plaintext password interception. H3C S5500-SI series switches support snmpv 1/v2/v3 (simple network management protocol), and can 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, making device management more convenient, and support SSH2.0 and other encryption methods, making management more secure.
H3C S5500-SI series switches support VLAN division based on MAC address, which well solves the intelligent and flexible management of mobile office. Combined with the unique ACL publishing strategy based on global and VLAN, the user configuration is simplified and hardware resources are greatly saved. H3C S5500-SI series switches support PoE+. PoE power supply model can provide the maximum output power of 30W per port, and can supply power to more terminal devices such as 802. 1 1n wireless access points and video IP phones through Ethernet.
