在项目中遇到关于苹果客户端连接思科WIFI出现不稳定的情况,需要尝试把ISE从2.2升级到2.4版本,把升级的步骤分享给小伙伴们
第一步:准备工作
一、准备升级软件,先到官网下载ISE2.4 升级包,需要下载如下两个升级包
- URT 包 :ise-urtbundle-2.4.0.357-1.0.0.SPA.x86_64.tar.gz 用于检测当前ISE的运行环境以及安装一些必要的升级文件,保证升级过程是稳定,不会出现异常的情况
- Upgrade 包: ise-upgradebundle-2.0.x-2.3.x-to-2.4.0.357.SPA.x86_64.tar.gz包含升级到新版本所需要的系统文件
二、准备FTP环境
由于Upgrade包体积较大,我们常用的3CD软件会在文件传输过程中终端,导致升级无法完成,建议使用SolarWinds SFTP软件,
三、备份
1.如果是虚拟机环境可以采用做快照的方式备份当前系统,若升级出现异常,可以快速恢复
2.非虚拟环境,可以备份系统的当前配置
第二步 升级系统
升级需要从Secondary 开始,升级完secondary之后,在升级Primary
一、配置 repository
repository upgrade
user admin password plain cisco123
crypto host_key addhost 192.168.42.108
二、安装URT包
application installise-urtbundle-2.4.0.357-1.0.0.SPA.x86_64.tar.gz upgrade
Save the current ADE-OS running configuration? (yes/no) [yes] ?

当ISE的applicationserver为running的时候,可以通过网页对ISE进行管理了
