Cisco C9500-12Q-E | Catalyst 9500 12-Port 40G Switch, Network Essentials

Q: What license tier does the C9500-12Q-E include?
A: The C9500-12Q-E comes with Cisco Network Essentials license, which provides Layer 2 and Layer 3 switching capabilities, security features, and basic network automation. For advanced capabilities like SD-Access, MACsec, and enhanced QoS, upgrading to Network Advantage or DNA licensing is recommended.

Q: Can the C9500-12Q-E be used for data center spine deployments?
A: Yes, the C9500-12Q-E is well-suited for data center spine and campus core aggregation roles. With 12x 40 Gbps QSFP+ ports, 960 Gbps switching capacity, and support for VXLAN hardware offload, it can efficiently handle east-west traffic in leaf-spine architectures with low latency forwarding.

Q: Does this switch support stacking or clustering?
A: The C9500-12Q-E supports StackWise Virtual technology, allowing two physical switches to operate as a single logical unit for enhanced redundancy and simplified management. This provides sub-second failover and eliminates the need for traditional stacking cables, using standard network ports instead.

Q: What power supply options are available for the C9500-12Q-E?
A: The switch ships with one 950W AC power supply by default and supports dual 1+1 redundant power supplies for high availability. Compatible options include 650W, 950W, 1500W, and 1600W AC power supplies. A second power supply must be ordered separately for full redundancy.

Q: Is the C9500-12Q-E compatible with 10G or 100G optics?
A: The C9500-12Q-E has 12 QSFP+ ports designed primarily for 40G transceivers. While the platform is optimized for 40 Gigabit Ethernet, compatibility with specific transceiver types should be verified using the Cisco Transceiver Module Group compatibility matrix. For native 10G or 100G requirements, other Catalyst 9500 models may be more appropriate.
