FAQs

Q: What license tier is included with the C9500-24Y4C-A?
A: The C9500-24Y4C-A ships with Network Advantage licensing, which provides advanced Layer 3 routing capabilities including MPLS, VRF-Lite, EVPN, Segment Routing, and full StackWise Virtual support with SSO and ISSU.

Q: Can this switch support both 25G and 100G connections simultaneously?
A: Yes, the C9500-24Y4C-A features 24 x SFP28 ports that support 1/10/25 Gigabit Ethernet and 4 x QSFP28 ports that support 40/100 Gigabit Ethernet, allowing for flexible connectivity at different speeds across the same chassis.

Q: What stacking options are available for this model?
A: The C9500-24Y4C-A supports StackWise Virtual (SWV) technology, which allows you to connect two physical switches together to operate as a single logical unit using high-speed Ethernet cables. This provides redundancy and simplified management.

Q: Is PoE supported on this switch?
A: No, the C9500-24Y4C-A does not support Power over Ethernet (PoE). It is designed for high-speed connectivity in core and aggregation layers where PoE is typically not required.

Q: What are the typical deployment scenarios for this switch?
A: The C9500-24Y4C-A is ideal for enterprise campus core and aggregation layers, data center interconnects, and high-density environments requiring 25G server connectivity with 100G uplinks to the core or distribution layer.
