FAQs

Q: What license tier is included with the C9500-12Q-A?
A: The C9500-12Q-A ships with the Cisco Network Advantage license, providing advanced Layer 3 routing protocols including OSPF, EIGRP, BGP, VRF-Lite, SD-Access automation, and comprehensive network analytics capabilities.

Q: Can I use breakout cables to increase port density?
A: Yes, the C9500-12Q-A supports QSFP+ to 4x 10G SFP+ breakout cables, allowing you to convert each 40GbE QSFP+ port into four 10GbE ports for a total of up to 48 x 10 Gigabit Ethernet ports depending on your cabling and optics.

Q: Does the C9500-12Q-A support StackWise Virtual?
A: Yes, the Catalyst 9500 Series supports Cisco StackWise Virtual technology, enabling you to combine two physical switches into a single logical switch for simplified management, increased bandwidth, and enhanced high availability with Stateful Switchover (SSO).

Q: What power supply options are available?
A: The switch ships with one 950W AC power supply (PWR-C4-950WAC-R) by default and supports dual redundant 1+1 power supplies. A second power supply (AC or DC) can be ordered separately for full redundancy. The DC option is PWR-C4-950WDC-R.

Q: Is the C9500-12Q-A suitable for data center core deployments?
A: Yes, the C9500-12Q-A is purpose-built for enterprise campus core and aggregation layers as well as small to mid-size data center environments. It offers high-performance 40GbE connectivity, deep buffering, large forwarding tables, MACsec encryption, and supports SD-Access for intent-based networking.
