Hi All,


I have a 2811 running 12.4(4)T8

It says it has 256 MB RAM and 61 MB Flash!!??


I need to upgrade to an IOS, but all require 64 MB Flash.

According to the data sheet for this router, they should come with 128 MB Flash.


I only have remote access to this router and via SSH or SDM and it says 61 MB Flash.


I don't want to reboot the router with an image requiring 64 MB Flash (which are all the images) if it's going to die on me.


Please advise!


Federico.

Hello,


If you issue a "show file system" command, you will know the actual bytes

available. Sometimes, due to formatting, you may not see the full capacity

in the output. The image/SDM you are loading will be smaller than 64 MB. So,

it should be safe to load the new image onto the device.

Let me see ... You have a 2800 ISR G1 (very good) ... it has an external compact flash bay (getting better) ...


Let me put it this way, I have a number of 2800/3800 routers, Sup32/720 cards ... They all sport 2Gb compact flash cards ... and the manufacturer of these equipment don't sell 2Gb CF card.  *wink*, *wink*


Just a tip:  ISR G1's support UP to 2Gb CF and G2's support up to 8Gb.
