H3C S7500X-G Series High-Performance Converged Multiservice Core Routing Switch

High Performance

• Distributed Architecture: to achieve wire-speed non-blocking forwarding of IPv4/IPv6 traffics, with slot bandwidth up to 960Gbps (bidirectional) on S7503X-G and S7510X-G/S7510X-G-PoE, 640Gbps (bidirectional) on S7506X-G/S7506X-G-PoE.

• High Speed 40G and 100G cards: to elevate uplink bandwidth, and help build a high bandwidth Campus.

• Large entries cards: with max Mac and Route being larger than 700K, to meet the customers’ high requirements of all kinds of networks.

• Ultra-low forwarding latency: can be as less as <1µs to ensure a fluent use experience.

Multi-service Integration

• High level and multi-service Integration: integration of LAN & WLAN (Embedded AC), integration of security service (FW card), integration of PON (XEPON, XGSPON, GPON OLT card), to combine diverse service into one Chassis.

• Integration of Wireless network: with the feature of Embedded wireless AC: to delivers rich wireless functionalities, including refined user control and management, complete RF management and security control, fast roaming, outstanding QoS capability, providing customers with more options for building wired and wireless integrated networks.

• AON (Adaptive Optical Network): S7500X-G can integrate Ethernet line cards, AON PoE++ card along with OLT cards in one single chassis, carrying Optic-Electric Hybrid Network, Multichannel Optical Network, and Passive Optical Network in one single chassis at the same time to build a ‘Fiber optical to them room’ type of network, guaranteeing continuous bandwidth upgrades, enjoying the benefits brought by H3C AON solution, such as long distance PoE, simplified network architecture，centralized management, etc.

Strong Aggregation Ability

• Abundant Cards: 1G card, 1G PoE+ card, 1G+10G hybrid card, 10G Card,10G+25G hybrid card, to aggregate all types of networks.

• AON PoE++ card (32*10G + 16*25G): to provide long distance (1KM), high bandwidth PoE solution, H3C AON (Adaptive Optical Network) solution.

Security Assurance

• 256bits MACsec capability: MACsec is an industry-standard point-to-point link-level security technology, is supported on all ports on SF card to provide comprehensive Link level security solution, protecting the network from security threats on the deepest data level.

• NAC gateway: supports a variety of access authentication methods, and can be used as an authentication gateway for thousands of users. S7500X-G can play a key role in BYOD scenario, make the campus network user experience much more fluent.

• Control plane—The embedded protocol packet attack recognition module prevents attacks from Topology Change Notification (TCN), Address Resolution Protocol (ARP), and other protocol packets. Use of the MD5 algorithm for the OSPF/BGP/IS-IS routing protocols prevents network breakdown caused by illegitimate route update packets.

• Management plane—Use of SNMPv3, SSHv2, 802.1X and AAA/RADIUS user authentication, role-based user permission management ensures device access and management security.

• Forwarding plane—Enhanced ACL capability, Standard and extended ACLs, VLAN-based ACLs and uRPF to prevent targeted traffics from accessing the network in a packet-by-packet match manner. And S7500X-G also supports the advanced Microsegmentation technology, which decouples the access policy from IP subnet, makes the policy more flexible, and accurate.

Carrier-level Reliability

• 3ms Hardware BFD: to ensure the network continuity.

• M-LAG (Multichassis link aggregation, originated from DRNI): provides device-level redundancy and load-balance through the simplest link aggregation protocol.

• IRF2 (Intelligent Resilient Framework): device level reliability technology, virtualizes multiple switches into one virtual IRF system to provide Data Center-class availability, scalability and also simplifies the management complexity. IRF2 system can be formed over a distance of 80 km (49.71 miles).

• Supports a variety of high-availability features such as NSF, ISSU, Graceful Restart, Smartlink, etc.

• ERPS, RRPP with millisecond-level failover performance, help customer build a resilient Ethernet Ring network, improves the performance and efficiency.

• Redundancy in key components, such as MPUs, Fan tray, PSUs.

• Adopting Passive backplane hardware design to eliminate single point of failures.

• All modules and power supplies are hot swappable.

• H3C S7500X-G series can operate in extreme environment reliably for a long time, with a carrier-level reliability of 99.999%.

Intelligent O&M

• Embedded NMS Platform (SmartMC) to provide a light-weight, convenient network management solution.

• Compatible with H3C Intelligent SDN campus network solution (AD-Campus) to build a SDN campus network with high-level automation, intelligence.

• Supports Visualization technologies, INT, gRPC, Netstream, Telemetry Stream, etc.

IPv6 Ready

• Complete IPv4/IPv6 dual stack solutions: supports multiple IPv6 transition tunneling technologies, IPv4/IPv6 multicast technologies.

• H3C S7500X-G has obtained IPv6 ready logo (phase 2), strong evidence that S7500X-G is a mature series ready for commercial IPv6 services.

Cost-effective Design

• Differentiated and compact design: S7503X-M-G chassis hosts 124 ports in 4U chassis; Service ports integrated S7506X-G MPU provides 4*25G+6*100G service ports.

• MDC (Multitenant Device Context): separates one chassis switch into several virtual switches to lower the cost through this advanced virtualization technology.
