VIP Port Adapter Functions
With the show interfaces type slot/port adapter/port command, use arguments such as the interface type (Token Ring, and so forth) and the slot, port adapter, and port numbers (slot/port adapter/port) to display information about a specific serial interface only.
The following example of the show interfaces tokenring slot/port adapter/port command shows all of the information specific to the first 4R interface port (interface port 0) in chassis slot 3, port adapter slot 0:
Router# sh int tokenring 3/0/0
TokenRing3/0/0 is administratively down, line protocol is down
Hardware is cyBus TokenRing, address is 0000.0ca5.2300 (bia 0000.0ca5.2388) MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive set (10 sec)

Basic Configuration Guidelines
Following are instructions for a basic configuration: enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands depending upon the requirements for your system configuration.
Step 1 After you access the privileged level of the EXEC as described in the section “Using the
EXEC Command Interpreter” on page 37, enter the configure command:
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 slot/port. For example, if you are configuring the Token Ring interface 0 for a 4R port adapter installed in slot 3, enter the following command:
Router(config)# interface tokenring 3/0/0
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:
Step 4 Change the default shutdown state and enable the interface:
When you enable the interface by using the no shutdown command, the LED for 4 Mbps or 16 Mbps is turned on after about 5 seconds. The IN RING LED for that interface is turned on about 5 to 18 seconds later, when the port is initialized and is connected to the ring.
Step 5 Enter any additional configuration subcommands required.
Step 6 Repeat Steps 2 through 5 for each new interface.
