Hi,
I use a RB260GSP (CSS106-1G-4P-1S) switch and want it to aquire the IP adress by DHCP from the router.
I set Address Acquisition to "DHCP with fallback" but it always uses fallback.
When I set it to "DHCP only" I can not connect to the switch and have to reset it.
Is there a way to get DHCP working?
Firmware version is 2.7
Thanks in advance!

Re: DHCP on RB260GSP not working
Off hand, it sounds like it is not communicating with the router. Couple things to check:
Are you getting link lights at both ends of the cable between the switch and the router?
Are you using VLANs, and if so, are the VLAN settings between the switch and the router compatible?
Can you look at router logs to see if the router is seeing a DHCP request?
Does the switch require DHCP to be on a specific port (I have the same switch, but only using static IP, so I don’t know)?
Does the switch settings restrict access to certain ports or VLANs?
That’s what comes to mind while sitting on my train (no reference material available).

Re: DHCP on RB260GSP not working
Hi, thanks for your answer!
The switch is communicating with the router, I can access the webinterface, all attached devices are working.
I am not yet using VLANs.
The SwOS manual seems not to be updated to 2.7, there is no mention of dhcp, so I don't know if DHCP needs to be on a specific port.
I have not made any access restrictions yet.
The routers log tells me:
So I think the router would offer my switch an IP-Adress, but the switch still uses the fallback.
