Checking the VIP4 Installation
Using show Commands to Verify the VIP4 Status
The following steps use show commands to verify that the new interfaces are configured and operating
correctly.
Use the show version command to display the system hardware configuration. Ensure that the list
Step 1
includes the new interfaces.
Display all the current interface processors and their interfaces with the show controllers command.
Step 2
Verify that the new VIP4 appears in the correct interface processor slot.
Specify one of the new interfaces with the show interfaces type interface-processor-slot-
Step 3
number/port-adapter-slot-number/interface-port-number command and verify that the first line of the
display specifies the interface with the correct slot number. Also verify that the interface and line
protocol are in the correct state: up or down.
Step 4
Display the protocols configured for the entire system and specific interfaces with the show protocols
command. If necessary, return to configuration mode to add or remove protocol routing on the system
or specific interfaces.
Display the running configuration file with the show running-config command. Display the
Step 5
configuration stored in the RSP NVRAM using the show startup-config command. Verify that the
configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not
functioning properly, ensure that the network interface is properly connected and terminated. If you still
have problems bringing the interface up, contact a service representative for assistance.

commands. The outputs in this document are examples only.
Using show Commands to Display Interface Information
To display information about a specific interface, use the show interfaces command with the interface
type and interface address in the format show interfaces type interface-processor-slot-
number/port-adapter-slot-number/interface-port-number.
With the show interfaces command, use arguments such as the interface type and the interface address
to display information about a specific interface only. The following example of the
show interfaces fastethernet command shows information specific to a VIP4 with a Fast Ethernet port
adapter (PA-2FE) installed; the VIP4 is installed in interface processor slot 1:
Router# show interfaces fastethernet 1/0/0
FastEthernet1/0/0 is up, line protocol is up
Hardware is cyBus FastEthernet Interface, address is 0000.0c4c.8820 (bia 0000.0c4c.8820)
Internet address is 192.168.36.4/28
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255
Encapsulation ARPA, loopback not set
Keepalive set (10 sec)
Full-duplex, 100Mb/s, 100BaseTX/FX
ARP type:ARPA, ARP Timeout 04:00:00
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters 01:25:25
