Description |
| Feature set |
Bundle NX-OS image with EPLD Image |
Starting from NX-OS Release 10.5(3)F, we no longer provide a separate EPLD image. Instead, we have bundled the EPLD image with the NX-OS software images. This allows you to upgrade both NX-OS and EPLD images at the same time and decreases the installation time. We also provide you the option to skip the EPLD image and install only the NX-OS image. For more information, see Cisco Nexus 3600 Series NX-OS Software Upgrade and Downgrade Guide, Release 10.5(x). |
New Enhanced Features
Cisco NX-OS Release 10.5(3)F does not include any new enhanced features for the Cisco Nexus 3000 Series.
Hardware Features
Cisco NX-OS Release 10.5(3)F does not include any new hardware features for the Cisco Nexus 3000 Series.
Release Image
Cisco Nexus 3000 Series platforms support only 64-bit image. The 64-bit Cisco NX-OS image filename begins with "nxos64-msll” (for example, nxos64-msll.10.5.1.F.bin) and this image is supported on Cisco Nexus 3600 series fixed switches and Cisco Nexus 3500-XL series switches. 32-bit image is no longer supported.
Note: Nexus 3600 supports EPLD image. Starting from 10.5(3)F, Cisco NX-OS no longer provides a separate EPLD image for Nexus 3600 series switches. Instead, the EPLD image is bundled with the NX-OS image and so the image size is correspondingly larger.
Open Issues
There are no open issues for Cisco Nexus 3000 Series in Cisco NX-OS Release 10.5(3)F.
