Hi there, just purchased some cisco kit - 2 x Cisco 2501 Ethernet Dual Serial Router 16mb Flash / 16mb Dram / IP Plus 12.3 IOS. I've been working through configuring the ports, serial link and passwords etc... On some occassions when running a show running-config i see some memory errors... see below...

From what i can see the router is running out of memory and i'm not sure why? heres my 'show version' output.. It seems i have 32K on NVRAM, is this normal? if anyone could shed any light on this that would be great. Thanks! Garry

Just looking at my post again. According to the output my current config is 731 bytes and my NVRAM has 32K so i dont see any problems there. It seems RAM is exceeding it limit (i think) Does anybody have any ideas how I confirm this? Thanks,
Garry

Found some useful commands below which i'm going to work with... hopefully, this should put me on the right tracks.

Hi Sushil, thanks for the document! I did have a read through this yesterday, didn't get to far :-(. I've just been using the kit as a lab, the memory issue only occurs from time to time, not very often.

Hi.
Don't get me wrong, but if I look at the "show version" I can see:
>cisco 2500 (68030) processor (revision M) with 6144K/2048K bytes of memory.
So your router has only 8 MB RAM, right?

Hi,
I guess Frank is correct. The available RAM is 8 MB while what is required for the image you are running is 16 MB.
Plus, the IOS version which you are running 12.3.17a is a deferred release.
So you have two options either upgrade the RAM [I am not sure need to check more on this part] or to run some other IOS release which needs 8 MB Flash.

Frank, Sushil, thanks for the posts! I sent my seller some outputs of 'show memory', 'show version' and straight away then identified what you guys just quoted! not enough memory! They are sending me a 16DRAM module. Should be here tomorrow! :-) I'm still learning otherwise i would of expected to see this straight away. Goy my CCENT in 3 weeks. Thanks again!
