Gbic Excessive CRC/alignment errors

[gigolo]

Hi,

Using 2 PROCURVE 2510G-24 connected with 2 Gbic J4858C.

On one of them, on gbic interface we have many Excessive CRC/alignment errors. Result is poor network connectivity.

each gbic interface is set to auto and is connected to 1000FDx.

Here is then conf :

Hi

"each gbic interface is set to auto and is connected to 1000FDx"

Do you mean that the connected device is set to 1000FDx? If yes, the switch is trying to negotiate link settings, but the receiving end doesn't since it's forced. So set that to Auto as well.

Hi,

I mean gbic is on default settings (auto).

I switched the gbic interface, and errors gone away.

Strange but fixed.

Thank you for replying & help
