CISCO3650版本升级记录
安装模式与捆绑包模式
Cisco Catalyst 3650系列交换机有两种操作模式：安装模式和捆绑包模式。
这两种模式之间有一些细微的差别。有关详情，请参阅配置指南。
思科建议在操作时使用安装模式，因为此模式可以提供更完善的功能，引导时所需的资源也更少。
安装模式
这是交换机的默认模式。安装模式使用名为 packages.conf 的软件包调配文件来引导交换机。此外，闪存中还有.pkg文件。
捆绑包模式
如果您对使用传统的单片IOS®映像来启动交换机感到满意，那么BUNDLE模式可能比较熟悉。
捆绑包模式消耗的内存比安装模式要多，因为升级时会从捆绑包中解压软件包，并复制到 RAM 中。
模式验证
要执行模式验证，请输入 show version 命令：
3650-stack#show version Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 52 WS-C3650-48TD 03.06.04.E cat3k_caa-universalk9 INSTALL 2 52 WS-C3650-48TD 03.06.04.E cat3k_caa-universalk9 INSTALL
升级
要开始升级过程，请从Cisco网站下载IOS® XE .bin文件，并将其通过TFTP上传至交换机中。
在将 .bin 文件复制到单个交换机时，安装进程会自动将该文件复制到同一堆叠中的其他交换机。复制好文件后，输入如下命令：
3650-stack# software install file flash:cat3k_caa-universalk9.SPA.03.07.04.SE.152-3.E4.bin switch 1-2
当升级过程开始时，交换机将.bin文件推送到堆叠成员对等体。

清除闪存
升级完成后，旧版本的残留文件会保留在闪存中。要清除剩余文件，请输入software clean命令，而不是手动删除文件。此操作会清除交换机不再需要的文件。
