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

問題:SDLC設(shè)備不能連接到主機.Milan是連接SDLC設(shè)備的遠端peer.
建議:
用show dlsw peer命令顯示peer是up的.
milan#sh dlsw peers
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
Show dlsw circuits沒有鏈路產(chǎn)生.
milan#show dlsw circuits
milan#
Show interface 命令顯示SDLC 地址狀態(tài)是USBUSY,這表示我們已經(jīng)成功的連接到下端路由器上.
