After you configure the Loopback0 interface, which command can you enter to verify the status of the interface and determine whether fast switching is enabled?
Click on the arrows to vote for the correct answerA. B. C. D.
The correct command to verify the status of the Loopback0 interface and determine whether fast switching is enabled is:
C. Router#show interface loopback 0
Therefore, option C is the correct command to use. This command will display detailed information about the Loopback0 interface, including its status, line protocol status, bandwidth, and whether fast switching is enabled or not. For example:
Router#show interface loopback 0 Loopback0 is up, line protocol is up Hardware is Loopback Internet address is 10.0.0.1/32 MTU 1514 bytes, BW 8000000 Kbit/sec, DLY 5000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation LOOPBACK, loopback not set Keepalive set (10 sec) Fast switching enabled ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output never, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/0 (size/max) 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 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 packets output, 0 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 unknown protocol drops 0 output buffer failures, 0 output buffers swapped out
In the output, you can see that the Loopback0 interface is up and the line protocol is up, indicating that the interface is operational. Additionally, the "Fast switching enabled" line indicates that fast switching is enabled for the interface.
