Hi,
Anyone know why Intel 82543 gigabit cards report lots of carrier problems? I don’t know why Intel 82543 gigabit network card using external transceiver(reported by ethtool) since it is directly connected to HP Switch with CAT-6 RJ45 network cables. Any one can explain where is the external transceiver for the Intel 82543 cards? I tried to run “ethtool –s eth1 xcvr internal” trying to set its transreciver to internal(on-board) but the operation fails silently. Please help.
In contrast, Intel 82540 gigabit cards reports no carrier problems at all, and use internal transceiver(reported by ethtool).
The following are the output of commands ethtool and ifconfig:
[root@dumbboy root]# ifconfig eth1 | grep carrier
TX packets:56944847 errors:0 dropped:0 overruns:0 carrier:39363496
[root@dumbboy root]# ethtool -S eth1 | grep -E 'carrier|tx_packets'
tx_packets: 57027012
tx_carrier_errors: 39417377
[root@dumbboy root]# ethtool eth1
