FAQs

Q: What fabric modules are compatible with the N9K-X9736C-FX?
A: The N9K-X9736C-FX is compatible with Cisco Nexus 9500 fabric modules including FM-E, FM-E2, and FM-G. With five fabric modules installed in a homogeneous chassis (all 9736C-FX or 9736C-FX3 line cards), it delivers full 3.6 Tbps bandwidth per slot.

Q: Does this line card support port breakout configurations?
A: Yes, each 100G QSFP28 port supports flexible breakout configurations including 2x50G, 1x40G, 4x25G, 4x10G, and 1x1/10G, allowing you to scale port density based on application requirements.

Q: Is MACsec encryption available on all ports?
A: Yes, all 36 ports on the N9K-X9736C-FX feature hardware-based MACsec with 256-bit AES encryption at line rate, providing hop-by-hop security for sensitive data center traffic without performance impact.

Q: Can I mix this line card with other Nexus 9500 line cards?
A: Yes, the N9K-X9736C-FX can be mixed with EX, FX, FX3, and GX series line cards in the same Nexus 9500 chassis. However, in mixed configurations, the chassis supports a maximum of four fabric modules, and bandwidth per slot may be reduced to 6.4 Tbps.

Q: What licensing is required for this line card?
A: The N9K-X9736C-FX requires a Transport Services License (L-N9K-X9700TX) for operation. Additional feature licenses may be required for advanced capabilities depending on your NX-OS or ACI deployment.
