Chapter 1 Basic Router Configuration Configuring Basic Parameters Verifying Your Configuration To verify that you have properly configured the loopback interface, enter the show interface loopback command. You should see verification output similar to the following example. Router# show interface loopback 0 Loopback0 is up, line protocol is up Hardware is Loopback Internet address is 10.10.10.100/24 MTU 1514 bytes, BW 8000000 Kbit, DLY 5000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation LOOPBACK, loopback not set Last input never, output never, output hang never Last clearing of "show interface" counters never Queueing strategy: fifo Output queue 0/0, 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 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 output buffer failures, 0 output buffers swapped out Another way to verify the loopback interface is to ping it: Router# ping 10.10.10.100 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.10.10.100, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms Configuring Command-Line Access to the Router Perform these steps to configure parameters to control access to the router, beginning in global configuration mode. Step 1 Command line [aux | console | tty | vty] line-number Example: Router(config)# line console 0 Router(config)# Step 2 password password Example: Router(config)# password 5dr4Hepw3 Router(config)# Purpose Enters line configuration mode, and specifies the type of line. This example specifies a console terminal for access. Specifies a unique password for the console terminal line.
