High port density and powerful forwarding capacity
The H3C S9825-G series switches supports high-density 800GE/400GE/200GE ports, has powerful forwarding capabilities, and has flexible sub-card configurations, supporting a maximum of 32*800GE QSFP-DD, 64*400GE Q112/ QSFP-DD ports, 128*200G QSFP56 ports, with extremely high port density and strong forwarding capability, can meet the needs of high-end data center high-density servers without networking requirements for convergent access.
H3C Multichassis link aggregation
H3C S9825-G series switches support M-LAG, which enables links of multiple switches to aggregate into one to implement device-level link backup. M-LAG is applicable to servers dual-homed to a pair of access devices for node redundancy.
Streamlined topology: M-LAG simplifies the network topology and spanning tree configuration by virtualizing two physical devices into one logical device.
Independent upgrading: The DR member devices can be upgraded independently one by one to minimize the impact on traffic forwarding.
High availability: The DR system uses a keepalive link to detect multi-active collision to ensure that only one member device forwards traffic after a DR system splits.
Powerful visibility
With the rapid development of data center, the scale of the data center expands rapidly; reliability, operation and maintenance become the bottleneck of data center for further expansion. H3C S9825-G series switches conform to the trend of automated data operation and maintenance, and support visualization of data center.
INT (Inband-Telemetry) is a network monitoring technology used to collect data from the device. Compared with the traditional network monitoring technology featuring one query, one reporting, INT requires only one-time configuration for continuous data reporting, thereby reducing the request processing load of the device. INT can collect timestamp information, device ID, port information, and buffer information in real time.
Provides a variety of traffic monitoring and analytic tools, including sFlow, NetStream, SPAN /ERSPAN mirroring, and port mirroring to help customers perform precise traffic analysis and gain visibility into network application traffic. With these tools, customers can collect network traffic data to evaluate network health status, create traffic analysis reports, perform traffic engineering, and optimize resource allocation.
Supports realtime monitoring of buffer and port queues, allowing for visible and dynamic network optimization.
Supports PTP (Precision Time Protocol) to achieve highly precise clock synchronization.
Flexible programmability
The switch uses industry-leading programmable switching chips that allow users to define the forwarding logic as needed.
Users can develop new features that meet the evolving trend of their networks through simple software updates.
Powerful SDN capacity
H3C S9825-G series switches adopt the next-generation chip with more flexible Openflow FlowTable, more resources and accurate ACL matching, which greatly improves the software-defined network (SDN) capabilities and meet the demand of data center SDN network.
H3C S9825-G series switches can interconnect with H3C SeerEngine-DC Controller through standard protocols such as OVSDB, Netconf and SNMP to implement network automatic deployment and configuration.
Comprehensive security control policies
H3C S9825-G series switch supports AAA, RADIUS and user account based authentication, IP, MAC, VLAN, port-based user identification, dynamic and static binding; when working with the H3C iMC platform, it can conduct real time management, instant diagnosis and crackdown on illicit network behavior.
H3C S9825-G series switch supports enhanced ACL control logic, which enables an enormous amount of inbound and outbound ACL, and delegate VLAN based ACL. This simplifies user deployment process and avoids ACL resource wastage. S9825-G series switch can also take advantage of Unicast Reverse Path Forwarding (Unicast RFP). When the device receives a packet, it will perform the reverse check to verify the source address from which the packets are supposedly originated, and will drop the packet if such path doesn’t exist. This can effectively prevent the source address spoofing in the network.
Multiple reliability protection
The S9825-G series switch provides multiple reliability protection at both switch and link levels. With over current, overvoltage, and overheat protection, all models have a redundant pluggable power module, which enables flexible configuration of AC or DC power modules based on actual needs. The entire switch supports fault detection and alarm for power supply and fan, allowing fan speed to change to suit different ambient temperatures.
The switch supports diverse link redundancy technologies such as H3C proprietary VRRPE, and Smart Link. These technologies ensure quick network convergence even when large amount of traffic of multiple services runs on the network.
Excellent manageability
The switch improves system management through the following ways:
Provides multiple management interfaces, including the serial console port, , USB port, out-of-band management ports.
Supports multiple access methods, including SNMPv1/v2c/v3, Telnet, SSH 2.0, SSL, and FTP.
Supports standard NETCONF APIs that allow users to configure and manage the switch, enhancing the compatibility with third-party applications.
