Huawei s single-core switch with multiple exits

Huawei's S6700, S5735-L-V2, and S3700 series switches can function as single-core switches with multiple uplinks, supporting high-performance Layer 3 routing, stacking, and redundant exit paths. Core Switch CapabilitiesHuawei's S6700 series is designed for high-performance core or aggregation roles in campus networks and data centers. Each S6700 switch provides up to 48 line-speed 10GE ports, supporting both 1GE and 10GE access.

It offers high switching capacity, large buffering, and advanced buffer scheduling to ensure non-blocking transmission even under heavy traffic loads. The S6700 supports multiple uplinks, enabling redundant exit paths and load balancing for high availability and network resilience.

The Cloud

Engine S5735-L-V2 series provides 8/10/16/24/48 GE downlink ports and 4 GE or 10GE uplink ports, along with 2 x 12GE dedicated stack ports. These switches support iStack technology, allowing multiple switches to operate as a single logical unit with a single management IP, effectively creating multiple exit paths and improving redundancy. They also implement Ethernet Ring Protection Switching (ERPS) for millisecond-level protection switching.

The S3700 series offers Layer 3 routing, stacking (iStack), and multiple uplink options, making it suitable for core or aggregation deployment in enterprise networks. It supports enhanced Ethernet reliability technologies such as RRPP and Smart Link, which provide load balancing and millisecond-level failover across multiple exit paths. The iStack function allows multiple switches to be connected with stack cables, expanding system capacity while maintaining a single management interface.

Key Features for Multiple Exits

Stacking (iStack): Multiple switches can be combined into a single logical switch, providing multiple exit paths and simplified management. Redundant Uplinks: Core switches support multiple uplinks to aggregation or data center layers, ensuring high availability and load balancing. Layer 3 Routing: Supports OSPF, IS-IS, BGP, and static routing for flexible traffic distribution across multiple exits.

High Availability: Technologies like ERPS, RRPP, and Smart Link provide millisecond-level failover and redundancy.

Security and Qo

S: Comprehensive security policies and QoS features ensure reliable and secure traffic forwarding across multiple exit paths.

Deployment Scenarios

These switches are ideal for: Enterprise campus networks where a single-core switch aggregates multiple access switches. Data centers requiring high-speed 10GE access and multiple uplinks for redundancy. Scalable networks where stacking allows expansion without additional management complexity.

Huawei's single-core switches with multiple exits provide flexible, high-performance, and resilient network solutions, combining stacking, multiple uplinks, Layer 3 routing, and advanced redundancy technologies to meet enterprise and data center requirements.
