症状:router每次开机时都要通过串口重新设置,不是按照startup-config里的配置自动设置.<br /><br />机器型号: C1721<br /><br />routercare#show version<br />Cisco Internetwork Operating System Software<br />IOS ™ C1700 Software (C1700-Y-M), Version 12.2(4)YA2, EARLY DEPLOYMENT RELEAS<br />E SOFTWARE (fc1)<br />Synched to technology version 12.2(5.4)T<br />TAC Support: <a href='http://www.cisco.com/tac' target='_blank'>http://www.cisco.com/tac</a><br />Copyright &copy; 1986-2002 by cisco Systems, Inc.<br />Compiled Thu 11-Apr-02 21:54 by ealyon<br />Image text-base: 0x80008124, data-base: 0x807976DC<br /><br />ROM: System Bootstrap, Version 12.2(7r)XM1, RELEASE SOFTWARE (fc1)<br />ROM: C1700 Software (C1700-Y-M), Version 12.2(4)YA2, EARLY DEPLOYMENT RELEASE SO<br />FTWARE (fc1)<br /><br />routercare uptime is 2 days, 17 hours, 24 minutes<br />System returned to ROM by power-on<br />System image file is &quot;flash:c1700-y-mz.122-4.YA2.bin&quot;<br />.......<br /><br />routercare#show startup-config<br />Using 589 out of 29688 bytes<br />&#33;<br />version 12.2<br />service timestamps debug uptime<br />service timestamps log uptime<br />no service password-encryption<br />&#33;<br />hostname routercare<br />&#33;<br />boot system flash<br />enable secret 5 $1$/ByN$IVGHfOytoHLY./Hzz58GA/<br />enable password cisco<br />&#33;<br />ip subnet-zero<br />no ip routing<br />&#33;<br />&#33;<br />&#33;<br />&#33;<br />interface FastEthernet0<br />ip address 192.168.52.16 255.255.255.0<br />no ip route-cache<br />speed auto<br />half-duplex<br />&#33;<br />.........<br /><br />&quot;boot system flash &quot;是我加的.据说这款路由器是不需要这条的.<br /><br />routercare#show flash<br /><br />System flash directory:<br />File Length Name/status<br />1 4113476 c1700-y-mz.122-4.YA2.bin<br />2 570 startup-config [deleted]<br />3 600 startup-config<br />[4114840 bytes used, 12400232 available, 16515072 total]<br />16384K bytes of processor board System flash (Read/Write)<br /><br />有人说是firmware不对了,因为在这之前做过firmware的download和upload .按说版本没换啊.<br />想找一个新的firmware,可我在网上就是找不到相应的firmware.<br />请哪位高人帮我解决一下,让他开机后能自动启动配置文件,不要再用串口去手动设置了.我快急死了.

show version<br />的最后一行是 Configuration register is 0xA102<br />这里好像不对,请问怎么改?

config register 0X2102

应该是配置积存器的问题。我遇上过类似的问题。<br />发现路由器的配置修改后，重新启动后还是缺省的配置。<br />后来发现配置寄存器不是0x2102，<br />实际上在启动的时候忽略掉重新启动前所保存的配置了。
