cisco 2811C升级IOS

思科对应设备的IOS的特性表
2811C 有spservices和advipservices的IOS，advipservices的特性里面有PPTP WITH MPPE这个特性，spservices没有，很不幸，我买的就是spservices(show version可以看到信息.)
然后找到了很多2800nm-XXX的IOS，都启动不了，从ROM模式恢复了很多次
顺便写一下从ROM模式恢复IOS的方法
IP_ADDRESS=192.168.1.2
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=192.168.1.254
TFTP_SERVER=192.168.1.1
TFTF_FILE=(IOS文件名)
tftpdnld
这个命令是分大小写的
网上找了很多资料,都说是licensce的问题.很郁闷,不知道用什么渠道才可以弄到这个.
后来偶然的机会发现 从机器dump出来的IOS名字是 c2800nmc-spservicesk9-mz.150-1.M5.bin ,但IOS名称都是 c2800nm-XXX. 有什么不一样呢? 一个是 c2800nmc ,另一个是c2800nm ,这两个不兼容! 开始找疯狂的找 c2800nmc-XXX的IOS ,翻墙以后找到了一个文件 c2800nmc-advipservicesk9-mz.151-3.T.bin,开始用tftp灌进去,等待了半个多小时后,奇迹般的启动成功了
ppp enc mppe 可以执行.

最后,怎么看支不支持这个IOS呢?实际上我灌IOS的时候忽略了一个东西
Router#copy tftp://192.168.49.249/c2800nm-adventerprisek9-mz.124-24.T5.bin
Router#copy tftp://192.168.49.249/c2800nm-adventerprisek9-mz.124-24.T5.bin f
Router#$/192.168.49.249/c2800nm-adventerprisek9-mz.124-24.T5.bin flash:
Destination filename [c2800nm-adventerprisek9-mz.124-24.T5.bin]?
Accessing tftp://192.168.49.249/c2800nm-adventerprisek9-mz.124-24.T5.bin...
%Warning: File not a valid executable for this system
Abort Copy? [confirm]
实际上会提示这个IOS不能运行在这个平台上,如果可以用的情况呢?
Router#$/192.168.49.249/c2800nmc-spservicesk9-mz.150-1.M5.bin fl
Router#$/192.168.49.249/c2800nmc-spservicesk9-mz.150-1.M5.bin flash:
Destination filename [c2800nmc-spservicesk9-mz.150-1.M5.bin]?
Accessing tftp://192.168.49.249/c2800nmc-spservicesk9-mz.150-1.M5.bin...
Erase flash: before copying? [confirm]
直接会提示你要不要擦除
