检查show dlsw peer输出,我们看到:Peers: state pkts-rx pkts-tx type drops ckts TCP uptime TCP 172.18.16.156 DISCONN 0 0 conf 0 0 0 --
用debug dlsw peers命令决定问题:
DLSw:action_a() attempting to connect peer 172.18.15.156(2065)
DLSw:action_a(): Write pipe opened for peer172.18.15.156(2065)
DLSw:peer 172.18.15.156(2065), old state DISCONN, new stateWAIT_RD
DLSw:dlsw_tcpd_fini() for peer 172.18.15.156(2065)
DLSw:tcp fini closing connection for peer 172.18.15.156(2065)
DLSw:action_d(): for peer 172.18.15.156(2065)
DLSw:peer 172.18.15.156(2065), old state WAIT_RD, new stateDISCONN
DLSw:Not promiscuous - Rej conn from 172.18.15.166(2065)
诊断:试着打开peer172.18.15.156,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.
