交换过性能信息后,就要寻找目的MAC地址了,显示出所有的路由器能够到达的MAC地址(本地和远端)

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地址状态均是FOUND,请参看第五步.

SEARCHING表示在寻找本地MAC地址或目的MAC地址.此时用show interface serial命令查看该口连接的PU状态.

NOT_FOUND表示没有收到对PU轮询的应答.

VERIFY表示确认缓存内信息.

在SERACHING本地MAC地址或目的MAC地址.

Router#show interface serial 0

Serial1 is up, line protocol is up

Hardware is HD64570

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

Encapsulation SDLC, loopback not set

Router link station role: SECONDARY (DTE)

Router link station metrics:

group poll not enabled

poll-wait 40000 seconds

N1 (max frame size) 12016 bits

modulo 8

sdlc vmac: 4000.5555.00--

sdlc addr C1 state is DISCONNECT

cls_state is CLS_STN_CLOSED

VS 0, VR 0, Remote VR 0, Current retransmit count 0

Hold queue: 0/200 IFRAMEs 0/0

TESTs 0/0 XIDs 0/0, DMs 0/0 FRMRs 0/0

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

Last input never, output never, output hang never
