ASR1004(RP2) Code Upgrade

Hello experts, 

 

We have several ASR1004 which are running outdated IOSs. Cisco TAC advised to upgrade the IOS to the a more current one but mentioned that the upgrade process is a bit involving. I'v never upgraded an IOS on an ASR. Can someone advise on what is involved and if there are simple step-by-step procedure to accomplish this task? 

 

Much appreciated. 

 

Best, ~zK

Can you please post the

Can you please post the output to the command "sh platform"? 

 

When it comes to the ASR, I would recommend you upgrade both the IOS and the bootstrap.  If you are smart, you can do this with just ONE REBOOT only.  

 

1.  First, you go HERE.

2.  You are given three options:  ROMmon, IOS-XE software and the Protocol Pact. 

3.  You want to go and download the ROMmon and IOS-XE.  

4.  For the ROMmon, go straight to version 15.4(2r)S and download this version. 

5.  It's up to you what IOS you want so you'll need to download this too. 

IMPORTANT:  Before we go further, after you've downloaded the files, make sure you compare the individual MD5 hash value of the files against the MD5 hash values found in the Cisco website.  They need to match.  

6.  IOS "delivery" - I don't know how far is your appliance from your office nor do I know what your technical confidence is.  But if you know what you are doing and the appliance is not far away, you can move the files via a simple USB thumb drive.  If not, you can copy the files from your computer to the appliance via TFTP.   I'd recommend you use TFTPd32.

7.  Once both files are copied to the appliance it won't hurt to compare the MD5 hash values again.  The command to is "verify /md5 bootflash:IOS.bin <MD5 hash value from the Cisco website>".  

8.  If the MD5 hash values add up, what you want to do is set the boot parameters of your router to boot the new IOS first and boot the secondary IOS as a just-in-case.  To do this, you perform the following: 

 

config t
no boot system bootflash:OLD_IOS.bin
boot system bootflash:NEW_IOS.bin
boot system bootflash:OLD_IOS.bin
end
wr

9.   Once this is done, the final step is to start the upgrade of your bootstrap.  The command is "upgrade rom file bootflash:bootstrap_file all".  

10.  The process will take about 5 minutes and at the end of this, the router will prompt you to reboot the appliance.  

 

And that's it.

The simplest upgrade

The simplest upgrade procedure for the ASR1k is no different to any other router.

1. Put the new image on the bootflash

2. Change the boot line in the configuration to point to the new image

3. reload the router.

 

Some things that you may want to consider. When you upgrade the IOS image, it is best practice to check and upgrade the rommon's on the various Field replaceable units. The matrix of rommons are at:

http://www.cisco.com/en/US/docs/routers/asr1000/release/notes/asr1k_rn_sys_req.html#wp3001284

 

Finally, about the complicated upgrade procedure mentioned by the TAC, whilst I cannot comment without knowing the details, I suspect they were referring to the In Service Software Upgrades (ISSU) which can become fairly involved.
