Configuring Interfaces - Cisco 10BASE-FL Installation And Configuration Manual

Cisco 7200 Series and the 5EFL Port Adapter
Figure 21 shows the port adapter slots and interface ports of a Cisco 7206. The port adapter slot
numbers start with 1 and continue through 6 (slot 0 is always reserved for the Fast Ethernet port on
the I/O controller—if present). The individual interface port numbers always begin with 0. The
number of additional ports depends on the number of ports on a port adapter.
For example, the five interface ports on a 5EFL port adapter in port adapter slot 1 would have the
addresses 1/0 through 1/4. (See Figure 21.) If the 5EFL port adapter was in port adapter slot 5, these
same interface ports would be numbered 5/0 through 5/4. Port adapters can occupy any port adapter
slot. There are no restrictions.

You can identify interface ports by physically checking the slot/interface port location on the front
of the router or by using show commands to display information about a specific interface or all
interfaces in the router.
Configuring Interfaces
The following steps describe a basic interface configuration. Press the Return key after each step
unless otherwise noted. At any time you can exit the privileged level and return to the user level by
entering disable at the prompt as follows:
Use the following procedure to perform a basic configuration:
