Cisco 1720 cannot run 12.3T IOS images??

Post by drequ.. » Tue, 15 Mar 2005 21:45:27


Hi All,

I've a cisco 1720 router with maxed ram/flash (48/16) wich seems to be
unable to run 12.3T IP ADSL IPX AT IBM FW IDS PLUS IPSEC 3DES IOS
images.

It should as far as I know looking at

http://www.cisco.com/en/US/products/hw/routers/ps221/prod_bulletin091...

1720 is listed as a supported router for c1700-bk9no3r2sy7-mz 12.3T
images.

I've tryed with 12.3.7T and 12.3.11T but router complains about
insufficient memory on boot, recommending a smaller image.

So now what? 1720 is a supported router but it needs more ram than its
max in order to be supported?

TIA for any insights
David

 
 
 

1. Cisco 1720 IOS Image cannot be loaded

Hi,

I'm relatively new with Cisco Routers. I got a 1720 to play around with and
I accidentally deleted the IOS image.
(I still don't know how that happened), since that I get this error message
when the 1720 boot's up

loadprog: bad file magic number:      0x0
boot: cannot load "flash:"

 The thing is, I can't find that image anywhere, not on the Cisco Web / FTP
site and
it doesn't seem to be on the Documentation CD either.
