ICX7450-48 not forwarding packets

SadClouds — Wed, 29 Jan 2025 09:55:24 GMT

Hello, I have ICX7450-48 switch that does not seem to forward packets correctly. I'm new to this hardware and not sure if this is a misconfiguration on my side or a hardware fault.

The switch is running the following firmware version and was reset to factory defaults:

Port 1/1/1 is connected to Netgear unmanaged switch, which connects a few Linux clients.

Port 1/1/2 is connected to server ILOM.

If I try to ping from a Linux client, going via Netgear unmanaged switch, to ICX7450 port 1/1/1 and then to server ILOM on 1/1/2, then initially a few pings get through, but then I get "Destination Host Unreachable":

It looks like ICX7450 keeps queuing packets without forwarding them:

If I unplug cable from port 1/1/1 and plug it into another port, the issue gets resolved for a period of time and pings get through. Later on the issue reoccurs again on the new port.

Could anyone suggest what could be the cause?

Thanks.

I think the problem I was having was due to the router firmware image and ARP packets not getting through the various ports. I installed and booted the switch firmware image from the second partition and the issue seems to be resolved. Running "show arp" command on the switch now lists the relevant IP and their MAC addresses.

I assumed L3 switch could be used like L2 switch, but with the addition of various routing protocols when performing advanced configurations. May be that is not the case. Does anyone know if the default behavior of L2 protocols with SPR08095n.bin image is significantly different than with SPS08095n.bin image?

Thanks.
