Note
commands. The outputs in this document are examples only.
Using the show interfaces type module-slot-number/interface-port-number command displays the
status information about a specific type of interface—in these examples, an ATM interface.
Following is an example of the show interfaces command for the Cisco 7200 series routers:
Router# show interfaces atm 6/0
ATM6/0 is up, line protocol is up
Hardware is ENHANCED ATM PA Plus
MTU 4470 bytes, sub MTU 4470, BW 149760 Kbit, DLY 80 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ATM, loopback not set
Encapsulation(s): AAL5
8191 maximum active VCs, 1 current VCCs
VC idle disconnect time: 300 seconds
8 carrier transitions
Last input 00:37:33, output 00:26:16, 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: None
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
54033 packets input, 81670740 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
8763526 packets output, 296268354 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
Using the ping Command to Verify Network Connectivity
Using the ping command, you can verify that an interface port is functioning properly. This section
provides a brief description of this command. Refer to the publications listed in the
"Related
Documentation" section on page viii
for detailed command descriptions and examples.
The ping command sends echo request packets out to a remote device at an IP address that you specify.
After sending an echo request, the system waits a specified time for the remote device to reply. Each
echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not
returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!)
indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a
bad connection.
Following is an example of a successful ping command to a remote server with the address 10.0.0.10:
Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#
If the connection fails, verify that you have the correct IP address for the destination and that the device
is active (powered on), and repeat the ping command.
