Q-Logic 8100 SERIES manual Identifying the QLogic 8100 Adapter Network ID, Using ifconfig

6–Configuring NIC Functionality in the Converged Network Adapter Configuring the NIC in a Linux Environment

Using ifconfig

Use the Linux network interface configuration command ifconfig to modify the driver parameters that are listed in Table 6-2that can be modified with ifconfig.

For example:

1.Set the MTU of network interface eth0 to Jumbo

#ifconfig eth0 mtu 9000

2.Verify that the MTU has been changed.

#ifconfig eth0

Figure 6-26shows the new MTU value

Figure 6-26. Verify the MTU Value

Identifying the QLogic 8100 Adapter Network ID

To identify the adapter network ID:

1.Identify the QLogic 8100 Series Adapter NIC function as a PCI device. Figure 6-27shows 85:00.0 and 85:00.1 to be the PCI bus device IDs for the NIC function ports of a dual-port adapter. For example:

# lspci grep "QLogic Corp"

Figure 6-27. Identify NIC Function

2.Verify that QLogic NIC driver qlge is managing the PCI bus device ID as 85:00.0 and 85:00.1. For example:

# ls -l /sys/bus/pci/drivers/qlge
