Hi Fohdeeshalongshot, but have you tried rebooting the switch?
You may be out of luck there. IIRC the switch stacking links don't even run in normal 'Ethernet' mode, they use something called HiGig and it isn't a protocol that you will be able to pass across bridges.When I tried using 1gbps copper SFPs, I was unable to get the switch to stack; it complained the link wasn't 10gbps. I was hoping someone here might have experience, or eldritch knowledge, about whether I could use a cheap 10gbps SFP that might report 10gbps despite only being connected at 2.5gbps, and rate limit those interfaces to prevent drops. Anybody been down this road? If so, which SFPs do you like for this kind of adventure?
It's for managing cooling in a datacenter: all network ports are on the same side of the rack (servers AND switches) AND the air flows in the same direction1) What is the use case of an "intake air flow"? I though all rack switches have their rear fans exhaust airflow out?
If you have a switch with front to back airflow and use it as a tor switch it would pull hot air into a server rack -> more heat -> higher risk for failure (not just the switch but all other stuff inside the rack)Ok, so why would the fan be intake if all network ports are on the same side of the rack?
Yes.And what I want is the standard exhaust airflow switch if I have the switch ports in front and the server ports at the back, correct?
Are you sure the IoT device isn’t trying to use a hardcoded DNS server?I have an IoT device on my network which is not using the dns server on the ICX7250 and always defaults to 0.0.0.0. ( so cant resolve dns names).
It is entirely possible it is - I suspect that is the issue. In this case, it has a default dns server of 0.0.0.0 ( if you query the device for dns server info). Not sure if its returning 0.0.0.0 because its not getting the dns info from the ICX switch or its hardcoded. Can you give some pointers how to do the DNAT rule ? Where ? On my pfsense switch or on the ICX7250?Are you sure the IoT device isn’t trying to use a hardcoded DNS server?
