This platform has a Base license.

The flash permanent activation key is the SAME as the running permanent key.

2、升级

输入更新的license

# conf t
(config)# activation-key 0x4......................................

有可能会有这个提示，不知道为什么，不用理会

直到输入，说是请求的key和在缓存中的是一样的，也就是说已经将新的key写入了缓存

看下show activation-key，说缓存中的key和现在运行的key不一致

3、重启

保存wr，重启reload

再看activation-key

4、问题

一开始有log不停的输出，可以使用no logging console关闭
