M4300 with latest firmware. DHCP Snooping NOT working
we have a 4352pa switch with a strange issue, we setup server 2019 dhcp on port 5 and configured port for dhcp snooping as per instructions found on netgear website. After enabling Port 5 as the DHCP port, none of the PC's receive a dhcp. All ports are on Vlan 1 , using 192.168.x.x address. If we remove dhcp snooping for port 5, all PCs get dhcp address. Can anyone else try this on there switch and tell us if its a bug ??
As a test, we put a gsm7224 into the test environment, used same server 2019, enabled port 5 as dhcp snooping, dhcp scope works perfectly.
What is up with the 4352 switches ?

What is the current firmware of the M4300-52G-PoE+ (GSM4352PA) switch? If ever its not yet the latest version, I suggest you to update it then check if the same problem will occur. The latest M4300 firmware is v12.0.17.7 and you can download it here.

it is already on Firmware v12.0.17.7 the LATEST.
ALSO, We now tested on TWO M4352 Switch, latest firmware both running firmware v12.0.17.7 and DHCP snooping does NOT WORK.
On an OLDER GSM 7224 works fine. but on a newer M4352 NOT. ARE THESE FIRMWARES TESTED WELL BEFORE RELEASE??
What else can be tried ?
How is everything connected? Kindly post an image of your detailed network setup.

On the M4352 switch, DHCP Snooping is setup as follows:
Firewall is acting as internet Gateway and providing DHCP. So the setup is Firewall (LAN)--->Port 5 on switch. All PCs are on VLAN1
For example, we put computers on ports 31 and 32.
We enabled the following on the Switch.
DHCP Snooping MODE ON
MAC Validation ON
For the VLAN ID 1 and Enabled
For DHCP Snooping Interface Configuration, Port 5 is selected and Trust ENABLED.
After doing that, none of the PC's receive DHCP. Doing the same steps on a GSM7224 it works with DHCP Snooping.
Kindly post screenshots of the configuration you have made on the M4300-52G-PoE+ (GSM4352PA) switch as well as the configuration you have made on the GSM7224.
Kindly attached also the tech support file from both switches.
