Nexus 9300v and 9500v Lite NX-OS Image

About Nexus 9300v and 9500v Lite NX-OS Image

An additional image, NX-OS lite (nxos64-cs-lite.10.2.2.75.F.bin), is introduced in Cisco NX-OS Release 10.2(3)F. This has a reduced memory footprint, resulting in a much smaller image size than the earlier images for Cisco Nexus 9300v and 9500v. This image can be installed during the boot-up time, and the image bring up is faster than the earlier images. However, before loading the lite image, perform a write-erase-reload, as some of the configurations may not be valid.


Note

This image contains only base RPMs, which are needed to support deployment scenarios such as VXLAN EVPN, no F+L, with IPv4/Ipv6 underlay (OSPF/IS-IS), and M-site functionality including vPC on BL, PC/vPC, LACP, and DME/YANG/telemetry. Rest of the RPMs are omitted from the lite NX-OS image.
