FAQs

Q: What optics are compatible?
A: Standard 100G QSFP28 transceivers (e.g., SR4/LR4/DR), as well as QSFP28 DAC/AOC cables are supported. Always verify module compatibility with the specific software release.

Q: Does this base bundle include encryption features?
A: The base bundle does not include MACsec; choose an Enterprise/MACsec bundle if 802.1AE encryption is required.

Q: Is licensing required for advanced routing features?
A: Yes. Advanced features (e.g., MPLS/EVPN/Segment Routing) may require appropriate software licenses depending on the OS release and feature set.

Q: Can I mix different 100G optics across ports?
