Network show error

[D.Cheung]

hello, i have two servers Proliant BL685c which Linux SLES9.
Anyone could advise on why the error counts.Is it any hardware problem with network card?

More information is needed. The number of errors is fairly small now. It might have been caused by a one-time event, e.g. rebooting a network switch.

Monitor the network statistics periodically for a while (a few hours). Is the number of errors growing? If it grows, does the growth seem constant (i.e. X errors per Y packets on average) or bursts of errors at certain times?

This might be a hardware problem in the NIC, but it also could be a slightly loose cable connector, a slightly damaged cable, or a rebooting network switch. It might also be a hardware problem in the switch port.

It might also mean that someone has tested the failover functionality of the NIC bonding by intentionally disconnecting the eth0 network cable while the system was running.

Shalom,

I see no problem with this output.

I would worry about this if there are performance problems or significant issues connecting to a system.

A bond with only one interface?

Anyhow, ethtool -S will give a more detailed report of interface statistics. From the output above, I'm guessing the errors are FCS - Frame Check Sequence errors (perhaps called CRC errors but you should check the ethtool -S output. If you have further questions about the ethtool -S outputput post the output here.

hi rick
thanks for your suggestion,it shows rx_crc_errors 954. Is it any hardware problem? pls advise,thanks

CRC errors could be from any number of causes. It could be a marginal cable, it could be a marginal port on either end of the cable. The massive stats dump was a bit much to go through, but depending on other stats it could also suggest a duplex mismatch - although in that case it would be 100 Mbit/s operation, and I don't know that is possible with a BL685 blade since those are always 1 Gig (or 10 Gig if you have an add-on).

If you are using switch modules in the chassis, being a BL685c, if these are on an add-on mezz card you might try swapping mezz cards. You might also consider swapping the BL685 into a different chassis slot. That would be how you try different "cables" since you are talking to a switch via the backplane.

If you are using a pass-through module, you might also consider swaping cables from the pass-through module to the upstream switch.
