Command Line Configuration

Note The three LAN ports each have their own LED indicators for activity/link status and network speed.

Command Line Configuration

A very minimal amount of command line configuration is needed on the Cisco NAC Guest Server appliance. This is to perform two tasks.

Configure IP Address and Default Gateway, page 2-3so that the appliance can be accessed on the network

Change Root Password, page 2-5on the appliance from the default

Configure IP Address and Default Gateway

To allow the appliance to be accessed on the network you need to configure the IP address and default gateway for the first interface on the appliance (eth0 or NIC1). To configure these details perform the following steps.

Step 1 Using either keyboard and monitor connection to the appliance, or serial console connection, authenticate to the command line interface. The user name for the console is root and the default password is cisco (Figure 2-3).

Figure 2-3 Authenticate to the Console

Step 2 To configure the network settings, type the command system-config-networkand press <Enter>. The Select A Device menu appears (Figure 2-4).
