GS116Ev2 / GS108Ev3 losing management IP if dhcp server is not reachable after 2 hour renewal period
There seems to be a bug within the dhcp client of GS116Ev2 (Firmware Version 2.6.0.43) and GS108Ev3 (Firmware Version 2.06.14). If the switch is configured to get its management IP address from a lo...
Hi there,
Sorry. Please use plus utility to renew your switch IP.
We will fix the DHCP client issue in new models, but not in old models.

Do I understand your suggestion right, that we should enable NDSP although in Firmware Version 2.6.0.43 the plus utility was disabled by default (due to security reasons)? This advice can not be serious, right?!?

Old models? GS116Ev2 (and GS108Ev3 - same problem) are current models still available and sold on the market?!?
I think Netgear needs some kind of change in strategy! In view of the current problems, I can no longer recommend Netgear "business hardware". For DHCP issue I would have to buy new hardware model which is currently unavailable (mine is not even 2 years old).
The latest Firmware update 2.6.0.48 uses a minimum MTU of 1500 (see German Forum) so that maintainance through Webinterface via VPN is not possible anymore. Some devices are not even reachable with pro utility after firmware update. All this without notifying customers in advance, and accepting to break well established setups? Furthermore the one and only response to customers who investigated time in tracking down problems is either to say we'll not fix - please buy next generation model- or thanks for tracking down the issue "corresponding information will be published on our pages in the next few days" but for security reasons you "should now set the MTU value to at least 1500 so that HTTP access can work properly"?
To sum up: Firmware of GS116Ev2 and GS108Ev3 is totally broken by desing. Instead of providing an adequate fix a crappy workaround is provided. This is unworthy of being called business hardware.
Maybe its time to distibute this approach to a wider range using social networks and professional journals / websites.

The DHCP behaviour on all Smart Managed Plus switches was and is always the same.

It's something I could understood decade(s) ago where NSTP had to pack "everything" into one frame (this problem was and is real!) because of packet fragmentation was (and is!) not possible due to the very simple embedded controller architecture and it's hmm substandad (fair enough?) IP stack, and DHCP implementation, ...
YeZ this is a completely unacceptable change, even in the eyes of "urgent" security fixes. Minimum MTU workable should be some 1400 to cover every possible use case.
