FAQs

Q: When should I choose the TR profile?
A: Choose TR when your priority is maximum forwarding throughput and predictable line-rate performance across all 100G ports.

Q: Are all QSFP28 modules supported?
A: Use QSFP28 modules that are qualified for your platform and software release; support may vary by optic type.

Q: Is mixing optics across ports allowed?
A: Yes, as long as each optic is supported by the platform and software, ports can be populated independently.

Q: Do I need special licenses for TR?
A: Licensing requirements depend on platform policies and desired features; consult your platform’s licensing guide.

Q: What chassis are compatible?
A: Designed for ASR 9000-class chassis. Verify slot, power, cooling, and fabric capacity for your specific model.
