43. TESTs 0/0 XIDs 0/0, DMs 0/0 FRMRs 0/0

44. RNRs 0/0 SNRMs 0/0 DISC/RDs 0/0 REJs 0/0 chain: C1/C1

45. Last input never, output never, output hang never

46. Last clearing of "show interface" counters never

47. Queueing strategy: fifo

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

49. 5 minute input rate 0 bits/sec, 0 packets/sec

50. 5 minute output rate 0 bits/sec, 0 packets/sec

51. 0 packets input, 0 bytes, 0 no buffer

52. Received 0 broadcasts, 0 runts, 0 giants

53. 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

54. 0 packets output, 0 bytes, 0 underruns

55. 0 output errors, 0 collisions, 19 interface resets

56. 0 output buffer failures, 0 output buffers swapped out

57. 6 carrier transitions

58. DCD=up DSR=up DTR=up RTS=up CTS=up

说明:

60. Encapsulation SDLC---串口打包方式为SDLC.

61. Router link station role: SECONDARY (DTE)---目前端口作secondary,由"sdlc role"命令设置.

62. sdlc vmac: 4000.5555.00-- ---由"sdlc vmac"设置的MAC地址.注意它的最后两位是留给PU地址的.

63. 在本例中,端口MAC地址是4000.5555.00C1.

64. sdlc addr C1 state is DISCONNECT ---该端口连接PU C1当前状态.有以下几种状态:

65. DISCONNECT -与PU未连接,次站没有发TEST或XID帧请求建立连接.请检查下面连接的PU是否启动

66. SNA进程,若是用DCE线缆连接PU请检查线缆是否正确,若是MODEM连接到远端PU上,请
