Configuring Additional NIC Cards Chapter 3 Installing the Clean Access Manager and Clean Access Server • If the NIC card is not recognized by BIOS (for example, for a non-appliance server machine), you may need to adjust IRQ/memory settings as per the manufacturer's recommendations. • Once the NIC is recognized by BIOS, it should be automatically recognized by the software (Linux). If for some reason, the NIC is recognized by BIOS, but not by Linux, then login to the system and run "kudzu". This will bring up a utility that helps you configure the NIC. To Configure an Additional NIC: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 To verify that the NIC has been recognized by Linux, type ifconfig ethn (where n is the interface number). For example, if adding a NIC to a system that already has two built-in Ethernet interfaces (eth0 and eth1), n is 2 and you enter ifconfig eth2. Verify that the output displays information about the interface including MAC address and transmit and receive counters. This means the interface is recognized by Linux and can be used. Change to the following directory: cd /etc/sysconfig/network-scripts Use vi to edit the ifcfg-ethn file for the interface, for example: vi ifcfg-eth2 Add the following lines into the file-replacing IPADDR, NETMASK, BROADCAST, and NETWORK values with the actual values suitable for your network: DEVICE=eth2 IPADDR=192.168.0.253 NETMASK=255.255.255.252 BROADCAST=192.168.0.255 NETWORK=192.168.0.252 BOOTPROTO=static ONBOOT=yes TYPE=Ethernet Save the file and reboot the system. The network interface is now ready to be used for HA. Note If the NIC card is not recognized by BIOS (for example, for a non-appliance server machine), you may need to adjust IRQ/memory settings as per the manufacturer's recommendations. Once the NIC is recognized by BIOS, it should be automatically recognized by the software (Linux). If for some reason, the NIC is recognized by BIOS, but not by Linux, then login to the system and run kudzu. This brings up a utility that helps you to configure the NIC. Note Static IP addresses must be configured for the CAM/CAS interfaces. DHCP mode is not supported for configuration of these interfaces. See Chapter 4, "Configuring High Availability (HA)"for details on configuring HA. 3-38 Cisco NAC Appliance Hardware Installation Guide OL-20326-01
