FAQs

Q: What chassis models are compatible with the N9K-X9732C-EX line card?
A: The N9K-X9732C-EX is compatible with Cisco Nexus 9504, 9508, and 9516 chassis (4-, 8-, and 16-slot configurations). It requires four N9K-C95xx-FM-E 100-Gbps fabric modules for maximum bandwidth performance.

Q: Can the QSFP28 ports be broken out to lower speeds?
A: Yes, each QSFP28 port supports flexible breakout configurations including 1 x 100G, 2 x 50G, 1 x 40G, 4 x 25G, 4 x 10G, and 1 x 1G Ethernet, providing deployment flexibility for mixed-speed environments.

Q: What is the difference between NX-OS mode and ACI mode on this line card?
A: NX-OS mode operates as a traditional Cisco Nexus switch with standard CLI and management, while ACI mode enables integration with Cisco Application Centric Infrastructure for policy-based automation and centralized management through APIC controllers.

Q: What role is the N9K-X9732C-EX designed for in the data center?
A: This line card is designed for aggregation-switch or spine roles in data center networks. It provides line-rate forwarding for all packet sizes, making it ideal for high-throughput leaf-spine architectures and core aggregation deployments.

Q: Does this line card support MACsec encryption?
A: No, the N9K-X9732C-EX does not include MACsec encryption capabilities. For MACsec support on 100G line cards, consider the N9K-X9732C-FX or N9K-X9736C-FX models with encryption-enabled ASICs.
