要测试ATM模块，真还不知道怎么测试，实际上很简单。
找一根光纤跳线，将OC3模块的收发口连接在一起。
启动路由后，如果有ATM子接口，把他删除：
conf t
no interface ATM5/0.1 point-to-point
在进入ATM接口，配置ip地址：
interface ATM5/0
ip address 10.10.10.10
255.255.255.0
no shut
atm clock internal
pvc 1/31
end
sh inter amt5/0
ATM5/0 is up, line protocol is up
Hardware is RS8234 ATMOC3
Internet address is 10.10.10.10/24
MTU 4470 bytes, sub MTU 4470, BW 155000 Kbit, DLY 80 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ATM, loopback not set
Encapsulation(s): AAL5
1023 maximum active VCs, 1 current VCCs
VC idle disconnect time: 300 seconds
Last input 00:01:17, output 00:01:17, 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: Per VC Queueing
30 second input rate 0 bits/sec, 0 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
187 packets input, 13664 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 6 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
193 packets output, 14096 bytes, 0 underruns
0 output errors, 0 collisions, 2 interface resets
0 output buffer failures, 0 output buffers swapped out
然后就可以做ping
#ping
Protocol [ip]:
Target IP address: 10.10.10.10
Repeat count [5]: 10000
Datagram size [100]: 3000
Timeout in seconds [2]:
Extended commands [n]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Sending 10000, 3000-byte ICMP Echos to 10.10.10.10, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (10000/10000), round-trip min/avg/max = 1/2/4 ms
这样就可以了！
