11–Troubleshooting Guidelines Check for System Errors

Check for System Errors

Linux

To check for system errors in Linux.

Check for error messages from the kernel using the following commands:

%dmesg

%cat /var/log/messages

Check routing table, gateway, and IP address conflicts for all interfaces using the following command:

%route

Check network interface transmit and receive counts during pings using the following command:

%ifconfig <network interface>

Use the wireshark, ethereal, tethereal, or tcpdump utility to capture packets.

Windows Server

To check for system errors in Windows Server:

Use the wireshark or ethereal utilities to capture packets.

Check for system error messages using the Windows event viewer.

Caveats

MSI-X Interrupts for Linux

Newer Linux OS distributions or kernel versions support MSI-X interrupts; some older versions do not support MSI-X. If MSI-X is not available on the OS, then use MSI or legacy mode in the OS.

Type the following command on the Linux host to check that PCI-MSI-X or PCI-MSI is enabled for the Ethernet interface:

% cat /proc/interrupts

Determine if the installed Linux kernel has the MSI configuration option enabled (earlier versions of the kernel may require an MSI patch).

Type the following command from the directory

and verify that the MSI configuration option is supported/enabled:

% make menuconfig
