Need help on how to figure out why there are errors on bond0(eth0)

Transfer speed is in KB

Hi Mario,

There seem to be a lot of frame errors, please try the following:

- replace the ethernet cable
- compare speed/duplex settings between server and switch - 'ethtool'

let us know how you go

cheers,

kbp

Hi,

speed/duplex should not be an issue coz other server have the same settings

Speed: 100Mb/s
Duplex: Full

Switch Cisco WS-CE500-24TT 24

May be cable issue let me give a try by changing it.
