Questions & Answers

  • What is Cisco C9500-24Y4C-E, and where does it fit in campus designs?

    It’s a Catalyst 9500 fixed-core switch with 24x 25G SFP28 and 4x 100G QSFP28 uplinks, ideal for campus core/distribution or small data center aggregation with high-speed uplinks.

  • How does C9500-24Y4C-E compare to models with 10G ports?

    It delivers higher 25G density for modern access stacks and servers. Choose it to future-proof bandwidth while keeping 100G core uplinks available.

  • Does it support StackWise Virtual or high-availability pairs?

    Yes. Form two-chassis pairs with StackWise Virtual for core redundancy, fast convergence, and maintenance flexibility.

  • What about routing and segmentation features?

    Runs IOS XE with advanced routing, VXLAN/EVPN (code dependent), and macro-segmentation using group policies for zero-trust designs.

  • Is MACsec available on C9500-24Y4C-E?

    Yes, many ports support MACsec. Verify specific license and code for 25G/100G MACsec needs.

  • How does it integrate with SD-Access?

    Acts as control-plane or border nodes, enabling fabric underlay and overlay for scalable policy-based segmentation.

  • What telemetry and automation options exist?

    Model-driven telemetry, NETCONF/RESTCONF, and DNA Center automation simplify provisioning and monitoring at scale.

  • Power and cooling considerations?

    Front-to-back airflow, redundant PSUs, and hot-swappable fans. Size power for optics and high-utilization scenarios.

  • Can it act as a small DC leaf or spine?

    Yes, for compact environments. 25G downlinks to servers or TORs and 100G spine connectivity are common.

  • Migration tips from older cores?

    Plan phased L3 adjacencies, deploy SVL, and validate routing convergence during change windows to avoid outages.
