交換過性能信息后,就要尋找目的MAC地址了,顯示出所有的路由器能夠到達的MAC地址(本地和遠端)
Router#show dlsw reachability
DLSw MAC address reachability cache list
Mac Addr status Loc. peer/port rif
0000.810f.6500 FOUND LOCAL TBridge-001 --no rif--
0006.e918.7b70 FOUND LOCAL TBridge-001 --no rif--
1000.5ae3.03f7 FOUND LOCAL TBridge-001 --no rif--
7500.9221.0000 FOUND REMOTE 16.201.30.250(2065) max-lf(4472)
7500.9221.0000 SEARCHING LOCAL
DLSw NetBIOS Name reachability cache list
NetBIOS Name status Loc. peer/port rif
SXUSER2 FOUND LOCAL TBridge-001 --no rif--
若本地MAC地址和目的MAC地址狀態(tài)均是FOUND,請參看第五步.
SEARCHING表示在尋找本地MAC地址或目的MAC地址.此時用show interface serial命令查看該口連接的PU狀態(tài).
NOT_FOUND表示沒有收到對PU輪詢的應(yīng)答.
VERIFY表示確認緩存內(nèi)信息.
在SERACHING本地MAC地址或目的MAC地址.
