chinamoon: 有一些命令，如：csim在CCIE实验室考试中使用，大家有空看看。 cisco 未公开的命令 Here you can find a collection of undocumented (not on Cisco Dokumentation CD or in online help) IOS commands: csim show interface switching show ip ospf statistics debug ip ospf monitor ttcp if-con no snmp-server sparse-tables who show region ps -c quit test aaa group radius With the command csim you can emulate a voice call. It′s like sombody calls the specified number. Usefull, if you don′t have physically access to telephone: Sucessfull call: wg1r1#csim start 089150 csim: called number = 089150, loop count = 1 ping count = 0 csim err csimDisconnected recvd DISC cid(21) csim: loop = 1, failed = 1 csim: call attempted = 1, setup failed = 1, tone failed = 0 Call to a not defined number: wg1r1#csim start 089151 csim: called number = 089151, loop count = 1 ping count = 0 csim err:csim_do_test Error peer not found -------------------------------------------------------------------------------- With show interface switching you can see in detail, which protocols are process, fast or elsewhere switched. It′s helpfull for traffic engineering: wg1r1#sh interfaces switching Ethernet0/0 Throttle count 0 Drops RP 0 SP 0 SPD Flushes Fast 0 SSE 0 SPD Aggress Fast 0 SPD Priority Inputs 5700 Drops 0 Protocol Path Pkts In Chars In Pkts Out Chars Out Other Process 8821 983982 7806 468360 Cache misses 0 Fast 0 0 0 0 Auton/SSE 0 0 0 0 IP Process 32228 3339712 5786 611402 Cache misses 0 Fast 92667 8980418 133414 189720295 Auton/SSE 0 0 0 0 DEC MOP Process 0 0 130 10010 Cache misses 0 Fast 0 0 0 0 Auton/SSE 0 0 0 0 ARP Process 6440 386380 195 11700 Cache misses 0 Fast 0 0 0 0 Auton/SSE 0 0 0 0 CDP Process 0 0 1302 404922 Cache misses 0 Fast 0 0 0 0 Auton/SSE 0 0 0 0 -------------------------------------------------------------------------------- With show ip ospf statistics you get detail informations about OSPF SPF. You can see the reasons for SPF and the calculation times: London#show ip ospf statistic Area 0: SPF algorithm executed 15 times SPF calculation time Delta T Intra D-Intra Summ D-Summ Ext D-Ext Total Reason 00:45:02 32 0 0 0 0 0 36 R, 00:41:00 28 0 0 0 0 0 28 R, N, 00:40:50 28 0 0 0 0 0 28 R, 00:38:13 28 0 0 0 4 0 32 R, X 00:34:18 24 0 0 0 4 0 32 R, N,SN,SA,X 00:07:37 24 0 0 0 0 0 36 R, 00:05:18 308 0 4 0 28 0 356 R, 00:04:05 24 0 0 0 4 0 28 R, 00:01:31 24 0 4 0 0 0 36 R, 00:01:21 24 0 0 4 0 0 36 R, -------------------------------------------------------------------------------- With debug ip ospf monitor you can monitor the OSPF SPF.

是CD中没有的? 那只有实验才知道了? 呵呵 哪些会造成不可恢复的后果?先另列出来吧.免得~~~到时候老大你会吐血

cisco 未公开的命令也就是说这是秘笈～大家快来看，可以打通关的秘笈耶～
