○ VLT upgrade with minimal loss for upgrades from 10.5.0.5 or earlier to 10.5.1.9 or later releases.
○ VLT upgrade with minimal loss in a VLT or VXLAN topology if network statements are used to advertise BGP prefixes.
● You must not make any configuration changes when the VLT peer nodes are running different versions of the software.
1. Download the new software image on both the VLT peer nodes (VLT-Peer 1 and VLT-Peer 2) from the Dell Support Site.
Extract the bin files from the tar file, and save the file in EXEC mode. Download the extracted bin file to the OS10 switch
using the image download command.
image download file-url
For example:
VLT-Peer1# image download scp://userid:passwd@hostip:/filepath
VLT-Peer2# image download scp://userid:passwd@hostip:/filepath
NOTE: Some Windows unzip applications insert extra carriage returns (CR) or line feeds (LF) when they extract
the contents of a .tar file, which may corrupt the downloaded OS10 binary image. Turn off this option if you use a
Windows-based tool to untar an OS10 binary file.
2. (Optional) View the current software download status in EXEC mode.
