No interface stats (ISP shows crc errors) - supermicro 5015A-EHF

scurry7

hi all!

I've got a supermicro 5015A-EHF with 2x Intel 82574L Gigabit LAN, they show up as re0 and re1. When I go to Status > Interfaces I get (on both interfaces):```
In/out packets 0/0 (0 bytes/0 bytes)
In/out packets (pass) 0/0 (0 bytes/0 bytes)
In/out packets (block) 0/0 (0 bytes/0 bytes)
In/out errors 0/0
Collisions 0


What can I do to verify that I'm getting errors on my end also?

"ifconfig re0" not really helpful either

re0: flags=8843 <up,broadcast,running,simplex,multicast>metric 0 mtu 1500
options=389b <rxcsum,txcsum,vlan_mtu,vlan_hwtagging,vlan_hwcsum,wol_ucast,wol_mcast,wol_magic>ether 00:25:90:06:c6:60

forgot…I'm running version 2.0.3-RELEASE (amd64)

If they show up as re0 and re1, those are Realtek, not Intel.

If there are no errors seen on Status > Interfaces, then there aren't any errors reported by the NIC driver.

So either they are seeing received errors (could be a bad cable) or something else is wrong with the packets arriving there.

I would first disable hardware checksums (System > Advanced, Networking tab) and see if that clears it up

Something odd going on here. As JimP said the re(4) driver is for Realtek NICs so either you don't have a standard configuration 5015A-EHF or your Intel NICs are somehow attaching to the wrong driver.

Either that or its a 5015A-H and not a EHF. http://www.supermicro.com/products/system/1U/5015/SYS-5015A-H.cfm?typ=H

^ That. A Realtek driver can't attach to anything but Realtek, so if it reports re0/re1, you have Realtek NICs. Not Intel NICs.

Still not entirely relevant to the main problem, aside from the Realtek NICs having a somewhat dubious reputation.

The key answer to the problem without opening the box.. is basically report back with the CPU. i would beable to determine which board is in there given the information that was provided with about 98% accuracy. the 2% would be because i had too much coffee this morning. Bios will tell you

It seems that the ISP is no longer showing crc errors ???

Also, it is the 5015a-h: http://www.supermicro.com/products/system/1U/5015/SYS-5015A-H.cfm?typ=H sorry for being misleading (I have about 8 or so of those supermicros in the field)

I noticed that on another supermicro (which also has realtek nics), it has the same problem except that the RRD Data is working fine on that box.

Think its just a problem with the realtek drivers and nothing to worry about?

thanks for your replies!
