Cisco Systems A9014CFD manual Verify the Cisco IOS image in the file system

Chapter 6 Software Upgrade

Upgrading the Cisco IOS image

Verifying checksum... OK (0xC7E6)

30551884 bytes copied in 199.636 secs (153038 bytes/sec) Router#

Step 6 Verify the Cisco IOS image in the file system.

Router# dir flash:

Directory of flash:/

1 -rw- 30551884 <no date> asr901-universalk9-mz.151-2.SNG

100401148 bytes total (69849200 bytes free) Router#

Router# verify flash:asr901-universalk9-mz.151-2.SNG

File system hash verification successful.

Step 7 Verify the Configuration Register.

Use the show version command to check the config-register value. The value is displayed in the last line of the show version output. It should be set to 0x2102.

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)# config-register 0x2102

Router(config)#^Z

Step 8 Verify the Boot Variable

The router tries to boot with the first file in the Flash. If the first file is not the Cisco IOS Software image, you need to configure a boot system statement in order to boot the specified image. If there is only one file in Flash and it is the Cisco IOS Software image, this step is not necessary.

Router#show run inc boot boot-start-marker

boot system flash asr901-universalk9-mz.151-2.SNG.fc1 boot-end-marker

Router# Router#conf t

Enter configuration commands, one per line. End with CNTL/Z. Router(config)#no boot system

Router(config)#boot system flash asr901-universalk9-mz.151-2.SNG Router(config)#end

Router#

Router#show run inc boot boot-start-marker

boot system flash asr901-universalk9-mz.151-2.SNG boot-end-marker

Router#

Step 9 Save the configuration and reload the router.

Router# write memory

Router# reload

Proceed with reload? [confirm]
