Hello Has anyone heard if this has been exploited in the field. It seems to be a low CVE and was found during internal security testing? And it only affects a 9K that is in "stand-alone mode". I've got a pair of Nexus 9Ks in vPC HA mode and also the ...

Can I use these as Top of Rack switches as well ? It will be used as layer 2 switches utilizing port-channels to the 3-node server farm

For whatever reason I could not get scp to work on the 2960L to pull the firmware from the Nexus, but I was able to with sftp...interesting. Thanks for the tip

I'll check it out. So there would be no issue with putting 2960x firmware onto a Nexus to then push it to a 2960x firmware?
