Trouble uploading IOS via tftpd32

I have 3 2500 routers that have maxed out memory. I am trying to upload IOS 12.3 via tftp but I continue to run into problems. The transfer always fails when it reaches 14% completion and I get an error on the router.

Can anyone help?

Hi,

Can you try loading the smallest IOS you can get.

Re: Trouble uploading IOS via tftpd32

Thanks mohammedmahmoud. The image that I'm loading is installed and running on other 2501 routers so I don't think that it's too large. I'm wondering if the tftp software that I'm using is the problem.

Hi,

It can be.

Alternatively you can try to download the IOS from other router directly.

For instance I'm using a router to store small config files used by IP phones through tftp.

Re: Trouble uploading IOS via tftpd32

Here is a little more detail on the problem that I'm having:

I have 3 2500 routers. I purchased memory to max out the memory on all of the routers (16MB for each) and replaced the old memory. When I power up any of the routers it loads it's boot image and the prompt reads - router (boot)>

If I run the command the "show flash" it says

System flash directory:

No files in System flash

[0 bytes used, 16777216 available, 16777216 total]

16384K bytes of processor board System flash (Read/Write)

I want to load IOS version 12.3 so I try to load it via tftp.

router(boot)#copy tftp flash

System flash directory:

No files in System flash

[0 bytes used, 16777216 available, 16777216 total]

Address or name of remote host [255.255.255.255]?10.70.106.1

Source file name?c2500-is-l.123-5b.bin

Destination file name [c2500-is-l.123-5b.bin]?

Accessing file 'c2500-is-l.123-5b.bin' on 10.70.106.1...

Loading c2500-is-l.123-5b.bin from 10.70.106.1 (via Ethernet0): ! [OK]

Device needs erasure before copying new file

Erase flash device before writing? [confirm]Yes

Copy 'c2500-is-l.123-5b.bin' from server

as 'c2500-is-l.123-5b.bin' into Flash WITH erase? [yes/no]yes

Erasing device... eeeeeeeeeeeeeeeeeeee...eras

Loading c2500-is-l.123-5b.bin from 10.70.106.1 (via Ethernet0): !!!!!!!!!!!!!!!!!!!!!!!!!!

!!!!!!!!!!!!!!!!!Parity (control reg=0x718) Error, address: 0xE092E4 at 0x1098EA4 (PC)

I get the parity error and then it reboots. Anyone have any suggestions?

Re: Trouble uploading IOS via tftpd32

It looks like the flash memory is bad. I ordered 3 max memory kits for 3 2500's and 2 of 3 were bad. What are the odds of that happening? Anyway, they are replacing the memory for me.

Re: Trouble uploading IOS via tftpd32

there are more chances of being bad in this case as one of them is working. Do clean the Simm slots before inserting the memory simms.

Thanks

Re: Trouble uploading IOS via tftpd32

The Simm slots were working fine. I tested them with the memory of other working routers as well as the old memory that I was trying to replace. I understand your point though.
