准备工作

从官网下载最新固件,用3CDeamon设置tftp服务器,IP地址设置为与管理口或数据口同网段,管理口默认IP为192.168.50.50,数据口默认IP为192.168.49.50,下面示例是通过管理口传输固件。

升级步骤

先升级boot-image:copy tftp boot-image

再升级OS: copy tftp image2

重启:reload

重启后检查版本:show  version

image2升级完成并经过测试无问题后可升级image1:copy tftp image1

切换image1和image2的命令:boot image {image1|image2}

注意事项

有时升级前的交换机版本特殊如非常低,在 tftp 时可能失败,换其它不同的 tftp 服务器即可
一定要把两文件都上传后,再重起交换机
在从较低的版本如 VER 1.0 升级到一个很高的版本如 VER 7.6时,一定要仔细阅读升级要求说明,不能直接升到最终的版本,要先升级到一个中间的版本如 VER 6.8。
