Troubleshooting Network Card Driver Support Issues
Troubleshooting Network Card Driver Support Issues
Typically, the installation program automatically detects the network cards on the target machine and
loads the appropriate drivers. However, on certain machines, the cards may not be detected properly and
the drivers need to be loaded manually. The following is an example of how to load the drivers for several
types of cards.
loads the appropriate drivers. However, on certain machines, the cards may not be detected properly and
the drivers need to be loaded manually. The following is an example of how to load the drivers for several
types of cards.
To manually load the driver:
1.
Connect to the Cisco Clean Access Manager by serial cable and console into the box.
2.
Type:
cd /lib/modules/kernel-2.4.9-perfigo/drivers/addon/driver
(where
driver
= NIC driver name, such as
bcm5700
or
e1000
)
3.
Type:
insmod ./driver.o
(for example:
insmod ./bcm5700.o
)
4.
If the above results in no errors, edit the file
/etc/modules.conf
with vi or another editor. Add the
following two lines:
alias eth0 driver
alias eth1 driver
For example, for Broadcom 5700-based NICs, insert:
alias eth0 bcm5700
alias eth1 bcm5700
Or, for Intel e1000-based NICs, insert the following lines instead:
alias eth0 e1000
alias eth1 e1000
5.
The network card's operating parameters, such as speed and duplex, may also need to be hardcoded
in the configuration file. For example, to hardcode Intel e1000 gigabit cards (eth0 and eth1) for
100Mbps full duplex, add the following line to the file
in the configuration file. For example, to hardcode Intel e1000 gigabit cards (eth0 and eth1) for
100Mbps full duplex, add the following line to the file
/etc/modules.conf
:
options e1000 Speed=100,100 Duplex=2,2
shows operating parameters for various NICs.
6.
Save and close the files, and reboot the server using:
# service perfigo reboot
