Support both IPv4 and IPv6

H3C S5500-SI series switches support IPv4/IPv6 dual stack and hardware forwarding.

Full wire-speed, multi-layer switching

l H3C S5500-SI series switches offer L2/L3 wire-speed switching capacity. The product series offers 10GE uplink speed, satisfies the most demanding.

l H3C S5500-SI series switches is able to identify and process the traffic flows from L2-L4.

l With independent packet filters, all ports distinguish different flows and forward them with corresponding priority.

Excellent PoE (Power over Ethernet) Supply Function

H3C S5500-SI series supply PoE function for endpoint devices, providing power over copper Ethernet cable to endpoint (Powered Device, such as IP phone, WLAN AP).

l H3C S5500-SI 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 H3C S5500-SI series Switches are 802.3af compliant PoE switches.

l With PoE and Voice VLAN technology, these innovative switches can provide the perfect solution for a converged voice and data network.

l H3C S5500-SI series switches supports PoE Profile, that means PoE policy configurations applicable to different user groups are stored in the corresponding PoE Profiles. When users connect a PD device to the port that currently has PoE Profile stored, the switch will automatically apply the PoE configuration defined in the corresponding port’s PoE Profile to the PD device.

Flexible security control policies

l The H3C S5500-SI Series support EAD(Endpoint Admission Defense), It enhances the proactive defense capacity of network terminals, and restrains the spread of viruses and worms in a network. Additionally, it disables the access authorities of terminals that fail to meet the security requirements, preventing insecure terminals from endangering the entire network.

l The H3C S5500-SI Series support 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 that use earlier versions of 802.1x client or illegal clients from logging in.

l The H3C S5500-SI Series support 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. Further more, the H3C S5500-SI Series can Perform 802.1x authentication and MAC address-based authentication simultaneously.

l The H3C S5500-SI Series support The Guest VLAN function, this function enables supplicant systems that are not authenticated to access specific resources and thus perform the corresponding operations.

l Secure Shell V2 (SSH V2) offers security information protection and powerful authentication function to safeguard the Ethernet switch from attacks such as IP address spoofing and plain text cipher interception.

High reliability

l H3C S5500-SI series support STP/RSTP and multi-VLAN based MSTP, greatly improving redundant back-up for links and fault tolerance capability, so that the network can run with high stability.

l H3C S5500-SI series switches support link-aggregation (include manual link aggregation and LACP), it is a simple and cost efficient way to expand the bandwidth of a switch port and balance the traffic among all the ports in a link aggregation. In addition, connection reliability is enhanced.

Abundant QoS policies

l The H3C S5500-SI Series support L2~L4 complex flow classification based on source MAC address/destination MAC address/source IP address/destination IP address/ports/protocols.

l The H3C S5500-SI Series support 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) and SP + WRR.

l The H3C S5500-SI Series support Committed Access Rate (CAR) and limit the traffic speed in the 64Kbit/s granularity.

l The H3C S5500-SI Series support packet redirection

l The H3C S5500-SI Series Support remarking of 802.1p and DSCP priorities.

Diversified System Configuration and Management Modes

l The H3C S5500-SI Series support Simple Network Management Protocol (SNMP) v1/v2/v3 and RMON (Remote Monitoring) v1, 1/2/3/9 groups of MIBs, they be managed by NMS. They can be managed by general network management platform such as OpenView, and H3C iMC network management system.

l The H3C S5500-SI Series support Command Line Interface (CLI), Web based network management, modem dial-up and telenet which make the equipment management more convenient.

l The H3C S5500 Series support 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 need a public network IP address, it can save public IP address greatly and manage the network more efficiently.
