有没有遇到过升级IOS后无法敲crypto命令? 为什么升级后就敲不上了?
场景:
======

-客户做了IOS升级,之后发现一些命令敲不上了.

switch(config)#ipssh?
%Unrecognized command
switch(config)#crypto?
%Unrecognized command
switch#crypto
Translating"crypto"
%Unknown command or computer name, or unable to find computer address

背景知识:
=======

什么是K9镜像?

The K9 image consistsof cryptographic features such as Secure Shell (SSH) Protocol and support forIP Security (IPSec)
//K9镜像包含加密特性,例如:SSH和IPSec
//non-K9镜像不支持这些特性

解决办法:
========

-升级选择IOS时,保持所选IOS特性一致, 例如升级前后都使用有K9关键字的IOS.
