1. Determine the slot number of the module.
host1#show version
2. Determine the port number of the module.
3. Determine whether the interface already has an IP address.
host1#show ip interface fastEthernet 6/0
If the interface already has an IP address, go to step 5. Otherwise, proceed with
step 4.
4. Configure an IP address on the interface.
host1#configure
Configuring from terminal or file [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
host1(config)#interface fastEthernet 6/0
host1(config-if)#ip address ipAddress [ mask ]

Task 5: Mount the CD on the Network Host
The way you mount the CD on the network host depends on the type of computer
you use, the operating system, and the network configuration. To find out how to
mount a CD on the network host, review the manual for the operating system, or
check with your network administrator.
Task 6: Configure Access to the Network Host
To configure access to the network host:
1. Use the ping command to determine whether the E-series router can reach the
network host.
host1#ping hostname
If the E-series router can reach the network host, go to the next section.
Otherwise, go to step 2.
2. Determine whether a route exists between the E-series router and the network
host.
host1#show ip route
If the appropriate route is displayed, go to step 5. Otherwise, proceed with
step 3.
NOTE: If an IP interface is not configured, the message “Invalid interface” appears.
