Can I upgrade code using dhcp code 43/ ztp? I have attempted this several times, I can get the switch to pull a config, or xsf, but it only pulls one file.
I have found a TAC paper :
https://extremeportal.force.com/ExtrArticleDetail?an=000078340
but this reads like Chineseium stereo instructions, it states that it will take several files including xos files, but my switches never ask for that file from the tftp server.( not using netsight) ( in fact the switches never ask for more than one file)
so the question is (yes or no / please no "here is a link to something you didn't ask")
If I get the option correctly formatted, will the switch download and install firmware from a tftp server?
If yes, does someone have an example of what files and server/ and what the option looks like.
Thanks for reading
DR

does it actually add the TLV format for every file? ( I assume it does just didn't whip out the hex converter)

While I would not suggest using EXOS as a DHCP server in a production network, I've used this for staging switches with configs and EXOS images a few times and it works well.
EXOS also does not seem to have any issues with sending the same sub-option multiple times, so it may be a good option for a lab/staging setup.
