Questions & Answers

  • What’s the key difference between Cisco C1000-48T-4X-L and C1000-48T-4G-L?

    Both are 48-port Gigabit access switches, but the C1000-48T-4X-L features four 10G SFP+ uplinks for higher backhaul bandwidth, while the C1000-48T-4G-L has four 1G SFP uplinks. Choose the 4X-L when you need faster aggregation to distribution or core layers, or want better future-proofing.

  • Is Cisco C1000-48T-4X-L suitable for enterprise edge or just SMB?

    It targets SMB and branch access but fits many enterprise edge scenarios. The 10G SFP+ uplinks prevent bottlenecks to aggregation switches, and its Layer 2 feature set, basic static routing, and security controls make it reliable for offices, schools, and retail networks.

  • Does C1000-48T-4X-L support stacking like Catalyst 9300?

    No. Catalyst 1000 models are standalone and do not support hardware stacking. If you need StackWise, advanced Layer 3, or modular uplinks, move up to Catalyst 9200/9300. The C1000-48T-4X-L emphasizes simplicity, predictable performance, and easy management for access deployments.

  • How is C1000-48T-4X-L managed—CLI or Web?

    You can use the built-in Web UI for quick setup, VLANs, and monitoring, or standard CLI via console/SSH for precise control. It also works with Cisco Business Dashboard for small-network visibility, firmware updates, and inventory, reducing the need for heavy automation frameworks.

  • What security features help protect the edge on C1000-48T-4X-L?

    It supports 802.1X port authentication, DHCP snooping, port security, storm control, and ACLs. These guard against rogue devices, spoofing, and broadcast storms, making it a safe choice for guest networks, IP phones, and IoT segments where basic but robust Layer 2 security is essential.

  • Where does C1000-48T-4X-L fit versus C9300-24T-A?

    C9300 offers StackWise, richer Layer 3, and modular uplinks for campus cores. C1000-48T-4X-L focuses on fixed Layer 2 access with 10G uplinks. If you need scale and routing, pick C9300; for cost-effective access with fast backhaul, the 48T-4X-L is ideal.

  • Is the C1000-48T-4X-L fanless and quiet?

    It uses quiet internal fans due to its 48-port density and 10G uplinks. For completely silent operation, consider smaller fanless C1000 models. In typical offices, the acoustic profile is suitable for closet or rack installations without disturbing users.

  • Which fiber modules can I use with C1000-48T-4X-L?

    Its four SFP+ uplinks accept 10G modules such as SR for short multimode runs, LR for single-mode distance, and DAC/AOC for cost-effective short links to adjacent switches. This flexibility helps match building backbones and inter-rack connections.

  • What are practical deployment scenarios for C1000-48T-4X-L?

    High-density office access, retail floors, and school labs where many Gigabit endpoints aggregate into 10G uplinks. It’s also common at branch sites connecting to a headquarters core over fiber, ensuring smooth video, VoIP, and file-sharing traffic.

  • How energy-efficient is C1000-48T-4X-L in daily use?

    It supports Energy Efficient Ethernet on idle links to cut consumption while maintaining performance under load. Combined with simple management and fixed hardware, it keeps total cost of ownership low for long-running access networks.
