求助Cisco 12000系列POS口时钟问题（已解决）

Question

本帖最后由 redhat_fans 于 2011-06-11 12:09 编辑

查看Cisco 12000系列的POS口（show int pos0/0），找了半天都没看到时钟配置项，不知道怎么回事，我的理解是：即便使用默认配置也应该会显示时钟模式的，POS口是10Gbit/s速率，烦请各位高手指点迷津，谢谢！

Answer 1

默认地 时钟配置是line，show run是看不到的，你show controller应该能看到

Answer 2

看了一下show interface pos 和 show controller pos 两个命令都没有显示时钟配置

Router# show interfaces pos 2/0/0

POS2/0/0 is up, line protocol is up

  Hardware is cyBus Packet over Sonet

  Description: PRI-T1 net to zippy (4K) to Pac-Bell

  Internet address is 1.1.1.1/27

  MTU 4470 bytes, BW 1000 Kbit, DLY 40000 usec, rely 255/255, load 1/255

  Encapsulation HDLC, loopback not set, keepalive set (3 sec)

  Last input 00:00:00, output 00:00:00, output hang never

  Last clearing of "show interface" counters 00:23:09

  Queueing strategy: fifo

  Output queue 0/40, 0 drops; input queue 0/75, 0 drops

  5 minute input rate 0 bits/sec, 1 packets/sec

  5 minute output rate 1000 bits/sec, 1 packets/sec

     1046 packets input, 54437 bytes, 0 no buffer

     Received 485 broadcasts, 0 runts, 0 giants, 0 parity

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     4013 packets output, 1357412 bytes, 0 underruns

     0 output errors, 0 applique, 0 interface resets

     0 output buffer failures, 0 output buffers swapped out

     0 carrier transitions

Router# show controllers pos

POS2/0/0

Answer 3

回复 4# redhat_fans

    时钟属于底层的配置，不在show int里，而是在show controller里，我从你的output里看见了“CLOCK RECOVERY”，说明是从传输网络获取时钟的，这个配置是默认的，也是正确的。

回复 5# quxiaosong

    谢谢，已经找到了，确实是在sh controller det 里，要看详细的描述。
