Last clearing of "show interface" counters never
Queueing strategy: fifo
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 packets output, 0 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped

3 transitions
The interface is now up, and you can ping the interface on Router B:
Router_A#ping 172.16.30.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.30.2, timeout is
2 seconds:
!!!!!
Success rate is 100 percent (5/5)
Scenario #2
Use the same network diagram found in Figure 5.7. The scenario is the same in
that you cannot get the interface on Router A or B to initialize. The problem is
different, so use Token Ring commands to find and solve the problem.
List Observations
The first command you issue on Router A is a show interface to0. The
results follow:
Router_A#show interface to0
TokenRing0 is down, line protocol is down
Hardware is TMS380, address is 0007.787c.e14b (bia
0007.787c.e14b)
