Learn how to install, configure and operate the Vyatta NOS, which helps drive our virtual networking & physical platforms portfolio.

Limitations and prerequisites

The following limitations and prerequisites apply to UEFI Secure Boot support.

Note: The availability of Secure Boot depends on hardware and firmware support. Ciena recommends that the technical specifications from the hardware vendor be checked.

The Vyatta NOS supports running with Secure Boot only on an IOMMU-enabled platform. Furthermore, the hardware and firmware must be able to assign each network interface to its own isolated IOMMU group. If either of these is not supported or enabled, errors are seen in show log.

Running in Secure Boot mode causes performance issues under heavy load on some Intel CPU models, such as the Intel Xeon D-1518.
