You can also identify interface ports by physically checking the slot/interface port location on the back
of the router or by using software commands to display information about a specific interface or all
interfaces in the router.
Configuring Interfaces
Following are instructions for a basic interface configuration using the configure command: enabling an
interface, setting interface ring speed, and specifying IP routing. You might also need to enter other
configuration subcommands depending upon the requirements for your system 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:
Router# disable
Router>
Use the following procedure to perform a basic configuration:
Step 1 At the privileged-level prompt, enter configuration mode and specify that the console terminal will be
the source of the configuration subcommands, as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 2 Specify the first Token Ring interface to configure by entering the subcommand interface type (token
ring) and slot/interface (port adapter slot number and interface number). The example that follows is
for the first interface of the port adapter in slot 6:
Router(config)# interface tokenring 6/0
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface
with the ip address configuration subcommand as follows:
Router(config-if)# ip address 1.1.1.10 255.255.255.0
