FAQs

Q: What port configurations does the C9400-LC-12QC support?
A: The line card supports either 12 ports of 40G QSFP+ or a mixed configuration of 4 ports of 100G QSFP28 plus 4 ports of 40G QSFP+. When 100G ports are configured, specific 40G ports are automatically disabled to maintain bandwidth allocation.

Q: Which supervisor modules are required for this line card?
A: The C9400-LC-12QC requires either the C9400X-SUP-2 or C9400X-SUP-2XL supervisor engine and is supported on Cisco IOS XE Software Release 17.12.1 or later. It is not compatible with earlier supervisor models.

Q: Does this line card support MACsec encryption?
A: Yes, the C9400-LC-12QC features hardware-based IEEE 802.1AE MACsec-256 encryption for secure, wire-speed data transmission across all QSFP ports, protecting data in transit at Layer 2.

Q: Can I install or remove this line card without powering down the chassis?
A: Yes, the C9400-LC-12QC is hot-swappable and can be installed or removed without powering down the chassis, minimizing downtime during maintenance or upgrades.

Q: What types of transceivers are compatible with this line card?
A: The line card supports standard QSFP+ transceivers for 40G connectivity and QSFP28 transceivers for 100G connectivity. Official Cisco QSFP28 SR4, LR4, and ER4 modules are supported for 100G operation, and breakout cables can be used for 10G or 25G connectivity.
