2851 Uploading files to flash SLOW

Answered Question
Mar 24th, 2009

upgrading a 2851 and adding Callmanager Express files to a brand new 2851. I've tried various connections between the router and my laptop (Gig NIC) to transfer files via TFTP and it is unbelievably slow. I've tried different TFTP servers, directly connecting to the router (crossover) ... all to no avail. Am I missing something? Why is it transferring so slow? I have no problems whatsoever with all other connections from my laptop. Help.

I have this problem too.

Thank you for the rating, but don't deserve it, since updating the bootstrap was Leo's suggestion.

BTW, I believe I recall on other 2800s, a bootstrap update, to take, will immediately reload the box. Also, procedure/command is different vs. normal IOS.

NB: Don't be surprised if the doesn't fix your issue since flash RAM/ROM isn't usually considered DRAM. But let us know whether it makes a difference or not.

Try upgrading the Bootstrap and compare the result.

What existing code is?

It might be a bug.

Can you try FTP to see if it is different?

It was slow with the shipping version ... don't recall what that was. Then I upgraded to 12.4.22T ... and it's just as slow.

Look at your processor and see if the CPU level has gone up (sh processor cpu history).

Yep ... pegging at 100% What can I do?

The issue you might be bumping into is, not all flash hardware supports fast recording. For example, copy an IOS image within the same device (i.e. not to/from external device) and it likely will perform just about the same.

On the issue of high CPU, that's not unusual. Cisco appears to invest their IOS development efforts in supporting the device's primary purpose, processing transit traffic. Things like upgrading a flash, as quickly as possible, likely isn't high on their priority list.

PS:

Another common reason for slow flash upgrades, if you use TFTP with high latency, it runs slow (which doesn't seem to be an issue in your case). FTP or RCP will copy much faster if latency is an issue.

When I initially went to upgrade the IOS from the shipped version to a newer version it was VERY slow, and finally bombed. When I rebooted it went into ROMMON mode and I used TFTPDNLD and it went FAST. After the router rebooted I resumed with copying CME files up to the router, but it went back to being reallly slow. I doubt it's a latency issue as this is a new isolated "lab" setup; the only two enpoints are the router and my laptop.

In light of Joseph's comment, what is the version of the Bootstrap?

C2800NM_RM2.srec.124-13r.T6 is a bootstrap for "DRAM access optimization".

Where do you download the Bootstrap software from? I couldn't find it in the downloads section....

Of Course - fair enough, thanks Leo!

Ok ... next question. How do I upgrade a Bootstrap image. I can't find the doc on CCO on how to do this....

Brian Carscadden Thu, 03/26/2009 - 08:21

Thanks guys that did it. Unfortunately the new ROMMON upgrade didn't speed up file transfers to the box. I'm going to try a few more things.

Leo Laohoo Thu, 03/26/2009 - 15:31

Thanks for the rating. Can you tell me what Bootstrap version did you upgrade to?

Bootstrap 12.4(13r).T5 can be found here:

http://tools.cisco.com/support/downloads/go/ImageList.x?relVer=12.4%2813r%29T5&mdfid=279316777&sftType=IOS+ROMMON+Software&optPlat=&nodecount=2&edesignator=null&modelName=Cisco+2801+Integrated+Services+Router&treeMdfId=268437899&treeName=Routers&modifmdfid=&imname=&hybrid=Y&imst=N&lr=Y

It's described as "Enhancement for device access in certain Cisco routers." and released on 06-Oct-2008.

Actually, it was this one:

C2800NM_RM2.srec.124-13r.T6

Release Date: 06/Oct/2008

C2800 ROMMON Upgrade: DRAM access optimization

Solved the problems I was having 100%.

"Solved the problems I was having 100%."

Indeed it did. Thanks for your part in helping out.

(incidentally, I'm an EDS alumnus, 1989-1994, so a kind regards in that respect as well...)

Hi Brian,

Glad that we were able to provide assistance and support to your issue.

NOTE: Left EDS last 30 December 2008. :-)
