DHCP Snooping on OS10
Hi, has anyone had any experience with getting DHCP snooping working on Dell OS10?
I have a pair of S5232F-ON running OS10 10.5.5.3 configured as a VLT pair.
The manual is pretty vague on DHCP snooping - it says all you have to do is configure "ip dhcp snooping trust" on the uplink that faces the DHCP server, and then enable "ip dhcp snooping" globally. I've tried this, and as soon as I turn on DHCP snooping globally, attached systems can't get DHCP any more. As soon as I turn off snooping, DHCP works again.
Support say that as no bugs have been reported with DHCP snooping, it must be that I've misconfigured the switch. This is entirely possible but not very helpful!
If anyone knows how to make it work for sure, I'd be very interested.
Thanks!

Hello kingtrw,
Is this something that was working and now it does not?
If so; Was anything done on the switch(s) around the time it quit working?
I think this may be useful:

I'll note that we cannot provide direct initial configuration support of your switches. We do have Deployment Services you can contract if needed. If you contact Sales they would be able to quote you for the service.
I hope the resources I am able to supply will be helpful for you. Forum members are welcome to share their experience.
