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. |
