Network Interface Card (NIC) Driver Not Supported 
Typically, the installation program automatically detects NIC 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 shows how to load drivers for several types of cards.
To manually load the driver: 
1.
Connect to the Clean Access Server by SSH. 
2.
Edit the file 
/etc/modules.conf
.
3.
Insert the following lines in the file for Broadcom 5700-based NICs: 
alias eth0 bcm5700 
alias eth1 bcm5700 
For Intel e1000-based cards, the following lines would be used instead: 
alias eth0 e1000 
alias eth1 e1000 
4.
The network card's operating parameters, such as speed and duplex, may also need to be specified 
in the configuration file. To configure the Intel gigabit cards (eth0 and eth1) mentioned above for 
100Mbps full duplex, for example, add the following line to the file 
/etc/modules.conf
options e1000 Speed=100,100 Duplex=2,2
5.
Save and close the files, and reboot the CAS using:
# service perfigo reboot
Resetting the Clean Access Server Configuration
If incorrect network, shared secret, or VLAN settings have rendered the Clean Access Server 
unreachable from the Clean Access Manager, you can reset the Clean Access Server’s configuration. 
Note that resetting the configuration restores the Clean Access Server configuration to its install state. 
Any configuration settings made since installation will be lost.
To reset the configuration:
1.
Connect to the Clean Access Server by SSH. 
2.
Delete the 
env
 file: 
# rm /perfigo/access/bin/env
3.
Then reboot using: 
# service perfigo reboot
You can now add the CAS to the CAM. Se
