Default OpenBSD 4.6 Install Complete, cannot ping

I finished an installation of 4.6 on a Dell PowerEdge R410 that has two NICs. The one is a Broadcom BCM5716 that was apparently just added to the bnx driver for this release and the other is a 4-port card made by Intel model 82575 that is also apparently just added to the em drivers in 4.6.

Anyway, once I am done the install I cannot ping anything. I have set up em0 on a simple subnet of with an IP address of and plugged into a switch. When I plug my laptop into the switch with an IP of I cannot ping the R410. If I plug my other laptop in on the switch with an IP of I can ping between the laptops but not to or from the server. I have changed ports on both the switch and the R410 and also changed ethernet cords to no avail. I have verified my subnet masks are correct as well and even reinstalled OpenBSD 4.6 just in case the drivers got corrupted during the install.

Also, I have changed subnets to see if there was something strange in that regard and had no luck there either. I have disabled pf to ensure nothing was getting blocked. I have also tried both NIC cards and they both have the exact same problem. I have also mirrored this installation in VMWare and it works fine so it makes me think there are issues with both the bnx and em drivers for these two network cards.

From the R410 I can ping the address assigned to em0 but when I attempt to ping my laptop on the same subnet I get the message:

ping: sendto: Host is Down

I just don't get it. This is such a basic set up as I am trying to ping a device on the exact same subnet and cannot do it. I am stumped. If anyone could help it would be appreciated.

Please disregard this message. As most things, the solution comes to me once I finally ask for help. I wasted a day and a half trying to figure this out and finally found the cause.

I had tried three different ports on my 48 port switch and all 3 would link up fine but apparently not pass traffic. I was able to pass traffic between two laptops plugged into the same ports so I have no idea what was going on. Possibly an ARP timeout issue or something. Anyway, once I moved to three other ports on the switch I connected fine. This was a really strange problem. Oh well, live and learn.
