路由器故障判断及排除(13)

13. 交换过性能信息后,就要寻找目的MAC地址了,显示出所有的路由器能够到达的MAC地址(本地和远端)

14. Router#show dlsw reachability

15. DLSw MAC address reachability cache list

16. Mac Addr status Loc. peer/port rif

17. 0000.810f.6500 FOUND LOCAL TBridge-001 --no rif--

18. 0006.e918.7b70 FOUND LOCAL TBridge-001 --no rif--

19. 1000.5ae3.03f7 FOUND LOCAL TBridge-001 --no rif--

20. 7500.9221.0000 FOUND REMOTE 16.201.30.250(2065)

max-lf(4472)

21. 7500.9221.0000 SEARCHING LOCAL

22.

23. DLSw NetBIOS Name reachability cache list

24. NetBIOS Name status Loc. peer/port rif

25. SXUSER2 FOUND LOCAL TBridge-001 --no rif-- 若本地MAC地址和目的MAC地址状态均是FOUND,请参看第五步. SEARCHING表示在寻找本地MAC地址或目的MAC地址.此时用show interface serial命令查看该口连接的PU状态.

NOT_FOUND表示没有收到对PU轮询的应答.

VERIFY表示确认缓存内信息.

26. 在SERACHING本地MAC地址或目的MAC地址.

27. Router#show interface serial 0

28. Serial1 is up, line protocol is up

29. Hardware is HD64570

30. MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255

31. Encapsulation SDLC, loopback not set

32. Router link station role: SECONDARY (DTE)

33. Router link station metrics:

34. group poll not enabled

35. poll-wait 40000 seconds

36. N1 (max frame size) 12016 bits

37. modulo 8

38. sdlc vmac: 4000.5555.00--

39. sdlc addr C1 state is DISCONNECT

40. cls_state is CLS_STN_CLOSED

41. VS 0, VR 0, Remote VR 0, Current retransmit count 0

42. Hold queue: 0/200 IFRAMEs 0/0
