路由器故障判断及排除(15)

DISCONN

DLSw: Not promiscuous - Rej conn from 172.18.15.166(2065)

诊断:试着打开peer 172.18.15.156,但不成功.DLSw+接收到来自172.18.15.166的打开请求,但是DLSw+拒绝它,因为这个peer没有定义.由此我们可以判断定义peer地址不正确.该peer地址为172.18.15.166就连通了.

Peers: state pkts-rx pkts-tx type drops ckts TCP uptime

TCP 172.18.16.166 CONNECT 2 2 conf 0 0 0 00:224:27

问题:SDLC设备不能连接到主机.Milan是连接SDLC设备的远端peer. 建议:

1. 用show dlsw peer命令显示peer是up的.

2.

3. milan#sh dlsw peers Peers: state pkts-rx pkts-tx type drops ckts TCP uptime

4. TCP 172.18.16.166 CONNECT 2 2 conf 0 0 0 00:224:27

5. Show dlsw circuits没有链路产生.

6.

7. milan#show dlsw circuits milan#

8. Show interface 命令显示SDLC 地址状态是USBUSY,这表示我们已经成功的连接到下端路由器上.

9. Router#show interface serial 3/7

10. Serial1 is up, line protocol is up

11. Hardware is HD64570

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

13. Encapsulation SDLC, loopback not set

14. Router link station role: SECONDARY (DTE)

15. Router link station metrics:

16. group poll not enabled

17. poll-wait 40000 seconds

18. N1 (max frame size) 12016 bits

19. modulo 8

20. sdlc vmac: 4000.5555.00--
