Core network switch

Performance, security, and scalability for your IT infrastructures

At the heart of any high-performance network architecture, core network switches provide high-speed connectivity between strategic equipment: servers, storage arrays, firewalls, routers, VLANs, hypervisors, etc. They play a central role in ensuring quality of service, data flow security, and information system resilience.
LOGIQE supports you throughout the entire lifecycle of your core network infrastructure, with multi-vendor expertise, a performance-oriented approach, and a constant demand for reliability.

Consulting and needs analysis for your core network switches

Before any deployment, our network engineers perform a thorough diagnosis:

  • Analysis of technical and business requirements: required bandwidth, expected resilience, segmentation needs, latency constraints, evolution over 3-5 years.
  • Audit of existing infrastructure: evaluation of interconnection diagrams, configuration survey, congestion points or SPOF (Single Point of Failure).
  • Proposal of topologies (Core-Distribution-Access, Leaf-Spine, dual-plane redundancy) adapted to field constraints (ERP, VDI, SD-WAN, ToR, etc.).

Our recommendations are based on a technical and economic benchmark of available solutions, while taking into account your technological standards.

Selection and benchmarking of switch manufacturers

We help you choose the most relevant solutions from the leading manufacturers on the market:

  • Cisco Systems: Catalyst & Nexus ranges, ideal for virtualized environments, SD-Access, high-density data centers.
  • Juniper Networks: Proven performance, stable Junos OS, advanced segmentation and routing features.
  • Aruba (HPE): Ideal for mobile/cloud infrastructures, with Aruba Central and native Zero Trust architecture.
  • Fortinet: Switches integrated with FortiGate via FortiLink, for unified security and centralized management.

Supply of equipment and licenses for your core network switches

  • Reliable sourcing (switches, SFP+ modules, transceivers, redundant power supplies, etc.).
  • Optimized logistics (anticipated stock, order tracking, secure delivery).
  • Integrated bundles with software licenses (L3 features, QoS, security, PoE, etc.) and support options.

Deployment, configuration, and migration of core network switches

We ensure seamless integration with a high level of technical rigor:

  • Detailed deployment planning (maintenance windows, rollback, minimal disruption).
  • Custom configuration: inter-VLAN routing, VRRP/HSRP, QoS, ACLs, LAG/MLAG, Spanning Tree, NAC.
  • Gradual rollout: controlled switchover, zone-by-zone migration, resilience testing.
  • Final validation: load testing, latency measurement, log verification, and dashboards.

Preventive maintenance, support, and network supervision

To ensure the stability and sustainability of your infrastructure:

  • Customized contracts: NBD, D+1, 24/7, with on-call service or remote maintenance.
  • Proactive monitoring: PRTG, Centreon, Zabbix, or manufacturer solution (Cisco DNA Center, Aruba Central, etc.).
  • Multi-vendor support: our teams liaise directly with manufacturers to escalate tickets.
  • Controlled software updates: firmware lifecycle management, validation of patches before release.

Operational training and technical documentation

LOGIQE is committed to strengthening your independence:

  • Technical training on-site or remotely, administrator or advanced level.
  • Support materials provided: architectural diagrams, configuration exports, post-incident recovery procedures.

Advanced services for the core network

For critical environments:

  • Active-active redundancy: SPOF-free architecture, LACP, vPC, and MC-LAG protocols.
  • Advanced network security: NAC (802.1x), micro-segmentation, NetFlow monitoring.
  • Automation and orchestration: Ansible, Python scripts, management via REST API.
  • Regulatory compliance: GDPR, NIS2, ISO 27001. Assistance with CNIL audits.

Custom integration according to publishers

Our engineers adapt configurations according to specific standards:

  • Cisco: Nexus OS/IOS-XE configuration, FabricPath management, VXLAN EVPN.
  • Juniper: Contrail integration, advanced BGP routing, management via Junos Space.
  • Aruba: ZTP deployment, secure tunnels, ClearPass compatibility.

Post-deployment monitoring and network scalability

Our support is long-term:

  • Periodic review of architecture, performance assessment, incident analysis.
  • Controlled scalability: expansion plan, addition of switches, port reallocation.
  • Technology watch: recommendations on future versions, SDN/Intent-Based Networking solutions.

FAQ – Core Network Switch

What exactly is the role of a core network switch in a modern architecture?

A core network switch interconnects critical IT infrastructure equipment (servers, racks, firewalls, hypervisors, etc.). It ensures high availability, logical segmentation (VLAN, ACL), and overall network performance through L3 routing, link aggregation, and redundancy functions.

Should you opt for a Core-Distribution-Access or Leaf-Spine architecture?

It depends on your volume, East-West flows, virtualization (VMware/Hyper-V/K8s), and scalability goals. LOGIQE helps you choose the most suitable architecture through a topological audit and a 3–5-year projection.

Can switches from different brands be deployed at the core of the network?

Technically, yes, via standards (LACP, STP, BGP, OSPF, etc.), but this complicates management. LOGIQE recommends homogeneous environments at the core, or validated interoperability with centralized supervision (multi-vendor NMS, API).

How can fault tolerance be guaranteed in the core network?

Through the use of redundancy protocols (VRRP, HSRP, vPC, MLAG), multiple paths, and dual power/fabric. LOGIQE designs resilient architectures without SPOFs and tests the ability to switch over without interruption.

What network certifications are required for internal teams?

LOGIQE offers customized training courses: switching/routing fundamentals, VLAN management, QoS, NAC security, manufacturer CLI (Cisco, Aruba, etc.), with course materials provided. Official certifications (CCNA, JNCIA, etc.) may be recommended depending on your objectives.
