VIP-4R/4T Installation and Configuration 43
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)
ARP type: ARPA, ARP Timeout 4:00:00
Last input never, output never, output hang never
Last clearing of "show interface" counters 2:56:26
Output queue 0/40, 0 drops; input queue 0/75, 0 drops
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 input packets with dribble condition detected
0 packets output, 0 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets, 0 restarts
0 output buffer failures, 0 output buffers swapped out
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:
Router(config-int)# ip address
ip address subnet mask
Step 4
Change the default shutdown state and enable the interface:
Router(config-int)# no shutdown
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.
