Netgear GS752TPv2 changed VLAN tagging after reboot.
Good afternoon everyone! I have a Netgear GS752TPv2 switch (version: 6.0.2.5) with a few VLANs: 11 - Administrative 31 - VoIP 101 - Public While not on-site (don't you love when that happen...
I took over this site from a tech that got let go. It was already in place, and I know I want to upgrade the FW. Putting a plan in motion on doing this after hours as I'm sure it will factory reset the switch. Thank you!
All the Release Notes are available on https://www.netgear.com/support/product/gs752tpv2/#download ... use the "View Previous Versions" for full reference. No word of a firmware update doing a factory reset. Still, the ubiquitous operational precautions apply (take full notices of the complete configurations, backup, backup, backup, ...)
For certain versions, Netgear does recommend against downgrading the firmware image to 6.0.8.x or earlier version after updating to 6.0.9.1 or later versions.
I heard better excuses for not keeping things on a current firmware (and security level) before.
Thank you for this information.
It is an excuse as I've only been managing this environment for 1 week, and do not believe in going gung-ho into a network. Document first my friend 🙂
Hi Kurr,
Welcome to the Community!
If the config has been saved, a sudden loss of power or reboot should not cause the port membership (tagging/untagging) at all. Could have been an isolated issue on your end. Have you considered scheduling downtime to see if the issue will persist by rebooting or powering off the unit?
Kind regards,

Confirming, I have two Netgear JGS524PE switches and this has been happening to me on and off for >2 years. If there is a power outage (I have UPSs but if the outage outlasts them), they reboot with a seemingly singular change in VLAN configuration. It seems to always only affect the ports with my access points which of course is the most problematic. Very frustrating!
I read on some forums this may be a bug that others are seeing. Any solutions out there? Thinking about replacing these switches with another brand if no solution. Thanks in advance!
