Layer 2/3 and Routing Capabilities

The s5735-l24p4s-a-v2 switch supports a robust suite of Layer 2 protocols and advanced Layer 3 routing:
Layer 2 Features▪ STP, RSTP, MSTP, ERPS for network loop avoidance and redundancy.
▪ Smart Link for fast uplink failover.
▪ VLAN support up to 4094 IDs, voice VLAN, MUX VLAN, VBST, GVRP.
▪ IEEE 802.3ah/802.1ag OAM, sFlow telemetry, DHCP snooping, ARP inspection, DoS and ACL protections.

Layer 3 FeaturesSupports IPv4/IPv6 static routing, RIP, OSPF, PIM DM/SM/SSM for multicast, and VRP-based routing capabilities suitable for aggregation and small core roles.

Operational Efficiency & Maintenance

Zero‑Touch DeploymentHuawei Easy Operation enables automatic provisioning via USB or remote batch deployment. Faulty switches can be replaced without manual config.

Telemetry & MonitoringReal-time telemetry streams to CampusInsight for intelligent fault detection, analytics, and service quality evaluation.
Smart UpgradesThe HOUP (Huawei Online Upgrade Platform) facilitates one-click upgrades and preloading to minimize downtime.

Security and Access Controls

Security is enforced through multiple layers: 

▪ 802.1X, MAC-based, hybrid authentication.
▪ Dynamic VLAN, QoS, ACL policy delivery.
▪ DoS mitigation and prevention against DHCP and ARP spoofing.
▪ DHCP snooping trust and ARP learning enforcement.

PoE Innovation: Powering Devices Smartly

Huawei s5735-l24p4s-a-v2 features intelligent PoE enhancements:
▪ Perpetual PoE ensures PDs remain powered during switch reboots or software upgrades.
▪ Fast PoE restores power to connected devices seconds after startup.
These are ideal for IP cameras, wireless APs, VoIP phones—even during maintenance cycles.

Scalability and Stacking with iStack

Support for Huawei iStack allows the s5735-l24p4s-a-v2 to stack up to several units, creating a single logical switch. This enhances scalability, redundancy, and simplifies network management as all units share a unified configuration and control plane.

Cloud Integration & Programmability

Designed for modern networks, the huawei s5735-l24p4s-a-v2 supports:
▪ Huawei Cloud management platform and HOUP cloud upgrade.
▪ NETCONF/YANG interfaces for programmable control.
▪ Python-based OPS for customized automation.
These features reduce on-site maintenance and fit well in cloud-managed environments.

Licensing Options

Flexible licensing supports both traditional feature licensing and Huawei’s IDN One (N1) model:
▪ N1 Basic: core Layer 2/3 functions.
▪ N1 Foundation: adds basic network automation and monitoring.
▪ N1 Advanced: includes CampusInsight and intelligent O&M.
This tiered structure enables cost-effective feature scalability.

Typical Use Cases

▪ Enterprise Campus Access – Provides Gigabit access with PoE+ for APs, IP cameras, phones.
