Cisco ISR4000路由器从3.x升级至Denali 16.2指南

· 2021-04-20 · # Cisco

在管理和升级ISR4000系列路由器时，我们发现IOS XE版本有3.x的，也有Denali 16.x的。我们可以将3.x版本升级到16.x版本，已实现生成环境的稳定性。在本文中，我们将向您展示如何将ISR4000从IOS XE 3.6升级到Denali 16.2.1。

您需要知道的事

路由器的最低ROMMON版本必须为16.2（1r）
以下过程只适合于ISR4000。ASR1000和CSR的过程可能略有不同

先决条件

从cisco.com下载ISR4000 ROMMON（除非您的路由器已经满足16.2（1r）或更高版本的要求）
从cisco.com下载ISR4000软件Denali 16.x IOS XE

步骤1：验证当前ROMMON版本

在这里，我们运行的15.4（3r）S3，早于16.2（1r），因此需要升级

ISR4321#show rom-monitor r0

R0 15030325 15.4(3r)S3
F0 15030325 15.4(3r)S3

步骤2：将新的ROMMON文件和Denali 16.x软件复制到路由器flash

ISR4321#copy ftp://<username>:<password>@<IP Address>/isr4300-rommon.162-1r.pkg flash:
Destination filename [isr4300-rommon.162-1r.pkg]?
Accessing ftp://*:*@172.16.32.40/isr4300-rommon.162-1r.pkg...
Loading isr4300-rommon.162-1r.pkg !!!!!!!!!!!
[OK - 2646988/4096 bytes]

2646988 bytes copied in 1.295 secs (2044006 bytes/sec)

ISR4321#copy ftp://<username>:<password>@<IP Address>/isr4300-universalk9.16.02.01.SPA.bin flash:
Destination filename [isr4300-universalk9.16.02.01.SPA.bin]?
Accessing ftp://*:*@172.16.32.40/isr4300-universalk9.16.02.01.SPA.bin...

[OK - 497494797/4096 bytes]

497494797 bytes copied in 199.583 secs (2492671 bytes/sec)

步骤3：验证文件是否上传成功，并校验MD5

ISR4321#dir bootflash: | in isr
17 -rw- 2646988 Apr 2 2016 11:00:47 -07:00 isr4300-rommon.162-1r.pkg
18 -rw- 497494797 Apr 2 2016 10:54:31 -07:00 isr4300-universalk9.16.02.01.SPA.bin

ISR4321#verify /md5 flash:isr4300-rommon.162-1r.pkg
.........................................Done!
verify /md5 (bootflash:isr4300-rommon.162-1r.pkg) = 2afd598e38c5420162762ec80b285f14

步骤4：进行ROMMON升级

这个过程大概需要5分钟，之后需要重新启动路由器

ISR4321#upgrade rom-monitor filename bootflash:isr4300-rommon.162-1r.pkg all
Chassis model ISR4321/K9 has a single rom-monitor.

Upgrade rom-monitor

To make the new ROMMON permanent, you must restart the RP.

ISR4321#reload

步骤5：验证ROMMON是否升级成功

ISR4321#sh rom-monitor R0

步骤6：升级软件Denali 16.x IOS XE

修改系统boot变量，保存配置并重启路由器

ISR4321(config)#no boot system bootflash:isr4300-universalk9.03.16.00c.S.155-3.S0c-ext.SPA.bin
ISR4321(config)#boot system bootflash:isr4300-universalk9.16.02.01.SPA.bin
ISR4321#wr
Building configuration...
[OK]
ISR4321#reload

步骤7：验证路由器是否已升级到IOS XE 16.x版本
