HP2824 CRC/FCS errors


here is the situation:

Name :

Link Status : Up

Bytes Rx : 3,069,881,422 Bytes Tx : 1,972,228,927
Unicast Rx : 348,278,145 Unicast Tx : 830,170,224
Bcast/Mcast Rx : 11,420,102 Bcast/Mcast Tx : 22,769

FCS Rx : 1,144,382 Drops Rx : 0
Alignment Rx : 0 Collisions Tx : 0
Runts Rx : 0 Late Colln Tx : 0
Giants Rx : 0 Excessive Colln : 0
Total Rx Errors : 1,561,680 Deferred Tx : 0

as you can see this is pretty bad; these errors happen on the gigabit uplink; on the other end is a Foundry 4000

so we went out and bought a new HP2824, upgraded to the latest firmware and connected it to the Foundry 4000;

result: is the table above; our switch was getting about 500 of these a second.

So, we swiped out Foundry, glblic ( yes we are using HP's brand ), cable everything but the HP2824.

HP support recommended to attach a HP2650 to the fiber drop and see if that causes any issues. HP2650 HAD NO ERRORS.

Did anyone experience a similiar issue? If yes, how did you resolve it ?

thanks in advance.

Re: HP2824 CRC/FCS errors

Hello Alex -

I have a couple of questions:

1. What OS version are you using? I know that you wrote 'latest', but 'latest' is dependent upon when you wrote your posting and, possibly, whether you got the OS from the ProCurve Web site or from a ProCurve support engineer.

2. Which mini-GBIC are you using: LH, LX, SX?
