GS752TPv2 and DHCP
Hello all, I hope somebody could help me with my problem. I recently got a GS752TPv2 and I am trying to make it work properly with my DHCP. Here is my installation right now for testing: Inte...
I am replying to myself because Netgear's technical support found the solution. Without really understanding why, it seems my router was creating a loop. I deactivated STP and now everything works perfectly so if somebody also has an issue getting an IP using DHCP, try deactivating STP!
By default, these switches are L2 devices spanning a transparent LAN. If neither the switch itself nor a connected computer does get a IP address assigned, the first guess is that the network connection from the router to the switch isn't up, or (unlikely as you stated the same issue happens following a switch factory reset) there are multiple VLANs configured for the management, and for the ports used for the link to the router and the computer.
That's exactly my problem, the switch should be transparent and gets an IP from my DHCP but it doesn't, even after the factory reset. I am using nominal configuration (no VLAN, nothing set up) and it doesn't work. I really don't understand. Is there a way for me to run a diagnostic on the switch? I just bought so I don't think the problem comes from the switch itself but (if I'm really unlucky) it might...
Link LEDs on both ends of the connection router<-> switch are OK?
You can always connect the switch Web UI by temporary re-configuring the computer to the 192.168.0.0/24 subnet (e.g. 192.168.0.123/24 255.255.255.0 subnet, default gateway any other address in that same subnet (and tick the connection config check which does exist on some overly smart OS) on applying the config. Now open the Web UI on http://192.168.0.239/ .... so you can check e.g. the port status on the router connection.
LEDs are ok: green and blinking. It seems the switch is "talking" but it doesn't work.
I attached a screenshot with port configuration of the swith: port 25 on my router and port 32 (not visible on the screenshot) to my computer. As you can see, status is up with speed 1GB (for both of them).
Is there a way I can see logs on the switch with IP attribution (connection to DHCP, failing, test...)?
Strange.
Using the very same LAN port on the router as for the single computer test?
Switching -> Address Table ... does this display some more MAC addresses from systems on your network?
Lets start with the Monitoring -> Logs -> Buffered Logs (not that I expect much ref. the DHCP)
When manually configuring the management interface IP ... can it be reached?
