用"show interface channel 3/2"显示逻辑通道口状态.
Router#sh int ch3/2
Channel3/2 is up, line protocol is up
Hardware is cyBus Channel Interface
MTU 4472 bytes, BW 98304 Kbit, DLY 100 usec, rely 255/255, load 1/255
Encapsulation CHANNEL, loopback not set

用"show ext ch 3/0 csna oper"显示CSNA通道连接设备状态.
"stat"替代"oper"获得CSNA通道连接设备的统计值.
确认CSNA通道连接设备状态为"setupComplet".
Router#sh ext c3/0 csna
Path Dv maxpiu time-delay length-delay
CSNA 0100 E1 20470 10 20470
Router#sh ext c3/0 csna oper
Path Dv Status SlowDown maxpiu time-delay length-delay
CSNA 0100 E1 setupComplet off 20470 10 20470
用"show ext ch 3/2 conn llc"命令确定SAPs值和CIP上打开的连接.
确认定义在XCA中的正确的SAP值在CIP internal Token Ring LAN adapter中已打开.
SHANXI2#sh ext c3/2 conn llc
LAN Token 0 Adapter 1 5808.0100.0000
No SAPs open on this interface
Total : SAPs opened = 0 Connections active = 0
如果CSNA通道连接设备状态是"setupComplet",正确的SAP值(i.e.,SAP 08)打开在正确的CIP internal
MAC adapter上,进入第七步.否则,问题可能是PATH/DEVICE或XCA Major Node.请检查通道地址定义是否
正确.若PATH/DEVICE正确,再在主机上"v net,act,id="命令确认XCA Major Node激活.
Router#sh ext c3/0 csna oper
Path Dv Status SlowDown maxpiu time-delay length-delay
CSNA 0100 E1 Close off 20470 10 20470
用"debug source-bridge"命令确定是否产生探测帧.如果确定以CIP internal MAC地址为目的的探测帧被接收到,请打开"debug channel vlan".
用"show ext ch 3/2 lan"命令显示CIP internal MAC adapters.核实CIP internal MAC adapter被
CIP microcode确认.
router#debug channel vlan
router#show ext ch 3/2 lan
Lan TokenRing 0
source-bridge 1000 1 100
Adapno Mac Address Name Vcnum
0 4000.1234.0001 544 0041 ACK ... ... ... ...... INU
如果CIP internal MAC adapters没有收到CIP的应答,(在"show ext ch 3/2 lan"显示不是ACK而是CRE或PNDIND),表明CIP microcode没有承认CIP adapter配置命令.在这种情况下,RP不发送探测帧给CIP.
如果CIP internal MAC adapters已经接收到CIP的应答,用"show ext ch 3/2 llc stat 4000.0008.0000",4000.0008.0000是CIP的internal MAC address,检查是否收到CIP MAC adapter的检测命令和应答.
如果正常,再用"show ext ch 3/2 llc stat 4000.0008.0000 08"命令确认SAP是否接收到XIDs和应答.如果没有应答,可能是Switched Major Node没被激活,或IDBLK/IDNUM不正确,或PU被占用.
在下端路由器上"show dlsw"命令查看串口连接的SNA end station状态.参阅DLSw+ Troubleshooting.
用"show llc2"显示当前已建立的LLC2链接.
SHANXI2#sh llc
LLC2 Connections: total of 1 connections
Channel1/2 DTE: 5808.0100.0000 4000.4700.10c1 04 04 state NORMAL
