Can you run SDM and CME 3.0 both on a Cisco 3640 with internal 64M flash and 128M RAM, plus 20meg external flash card? Plus any configuration documentation would be helpful?

Thanks in Advance.

Completely agree about irrelevant posts!

Cisco SDM is a web-based configuration tool that allows you to configure LAN and WAN interfaces, routing, Network Admission Control (NAC), Network Address Translation (NAT), firewalls, Intrusion Prevention System (IPS), Virtual Private Networks (VPNs), and other features on the router.

SDM will run on the 3640. Refer here for release notes -


For the 3640 router, you will need -

12.2(11)T6 or later releases

12.3(2)T or later releases

12.3(1)M or later releases



12.4(2)T or later releases

64 meg flash and 128 meg DRAM should be fine !

Some config guides are here -


SDM does not do any voice configurations. Since you are talking about CME 3.0 (or later) then you can use the CME GUI and CLI to configure the voice features. Refer here for configuration details -
