IOS FOR 3640 INFO

[maczen]

Bill,
I checked and this is the most recent Enterprise IOS with the FW/IPS/IDS 3DES IPSec featureset available that will run on the 3640 natively without needing to boot from a remote IOS (FTP/RCP/TFTP boot)

c3640-jk9o3s-mz.124-13a.bin

If you do a flash squeeze first then you may be able to fit something newer.. not sure but this should be more than sufficient for study purposes! Personally, I would opt to boot the routers from a TFTP and use the latest and greatest!

Hope this helps!

Billy the Pingster,

Is it OK that I just erase flash before I copy the IOS down from a tftp server? Running 32meg flash not partitioned.

For what I'm doing, do you think I need IPSEC or 3DES?

When you copy the IOS from a tftp server, it will ask if you want to erase the flash.

Billy---"squeeze flash" or "squeeze bootflash:" (CatOS) will permanently erase files previously deleted from the flash (erase flash:filename.bin).

Bill,
It won't matter what you have on flash if you are booting remotely! (via RCP/FTP/TFTP)

IPSec/3 DES.. That IOS will have both.. You will use the IPSec for your VPN stuff if you go the Security side doubt that the type of encryption used will matter for lab but it is nice to have the industry (or at least Cisco) recommended 3DES...

Burt,
Squeeze command (IOS since 12.2x for 3600 series)
