一次Cisco Nexus9508交换机版本升级
一次Cisco Nexus9508交换机版本升级
1 升级目的
客户处需要使用BGP EVPN VXLAN
这个feature需要7.0以上版本支持。当前版本为6.1，无法支持，所以需要升级.
1.1 当前版本：
Software
BIOS: version 08.06
NXOS: version 6.1(2)I3(3a)
1.2 目标版本：
7.0(3)I2(2B)
2 升级方式说明
升级方式可支持以下多种
FTP
TFTP
USB
如果是在现场，推荐使用USB方式，最为方便。本次的升级就是USB方式。
2.1 条件准备
新的IOS
U盘 (容量1G以上)
笔记本电脑
Console线
2.2 操作过程
2.2.1 保存当前设备配置
Nexus9508-1# copy running-config startup-config
[########################################] 100%
Copy complete.
2.2.2 插上U盘并格式化
这里是为了将U盘格式化为Nexus9508能识别的格式
Nexus9508-1# format usb1:
This command is going to erase the contents of your usb1:.
Do you want to continue? (yes/no) [y] y
Formatting usb1:
Formatting completed
2.2.3 拨出U盘插到电脑上，将新版本镜像copy to USB drive
2.2.4 U盘插到9508的引擎板上USB口，检查U盘内容![在这里插入图片描述]()
SWITCH-9508# dir usb1:
538114048 Apr 04 23:54:24 2016 nxos.7.0.3.I2.2b.bin
2.2.5 拷贝U盘中的IOS到bootfalsh
SWITCH-9508# copy usb1:nxos.7.0.3.I2.2b.bin bootflash:nxos.7.0.3.I2.2b.bin
Copy progress 100% 538114KB
Copy complete, now saving to disk (please wait)...
2.2.6 检查bootflash文件拷贝成功
SWITCH-9508# dir bootflash:

2.2.7 弹出U盘
弹出的命令和Linux环境中类似。
SWITCH-9508# unmount usb1:
2.2.8 检查IOS的MD5值
检查是否与官网的MD5值一致，若一致则说明文件无损坏。
SWITCH-9508# show file bootflash:nxos.7.0.3.I2.2b.bin md5sum
02c06a20fd815ae895928966c45ab08d
2.2.9 检查新版本的兼容性
这一步还是很有必要的，正式升级前检查兼容性，这一步操作不会影响业务，也不会导致网络中断。
SWITCH-9508# show install all impact nxos bootflash:nxos.7.0.3.I2.2b.bin
会弹出以下logging，只需要等待
Installer will perform impact only check. Please wait.
