CISCO 1721 Router Config and Software Type

I purchased a 1721 router recently and I would like to know if it has 3DES. I would like to use the rouyter for vpn. If it does not have 3DES, how can I get it?

I also need to know how to restore the defaults and upgrade the IOS. When an IOS upgrade takes place, does it wipe out current values?

Does 1721 support a web interface?

Support for 3DES depends on the the IOS feature set. You can use the feature navigator to determine if your IOS supports it.

http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

To restore the router to default (unconfigured), from the privileged mode prompt issue the "erase startup-config" command and then "reload". Do NOT save config if prompted.

The 1700's have a limited web interface.

When I do a write mem command, does that do the same as copying the running config to the startup config?

If you have the router on a SmartNet maintenance agreement, you can download it from Cisco. Otherwise, contact an authorized reseller.

"Write memory" and "copy running-config startup-config" accomplish the same thing.

When you say download it, all I have to do is download the IOS with DES?

I am doing work for a company that has a PIX under smartnet, I also have a login for the cisco site and my id is attached to the contract. So I can simply download the IOS version and update mine>?

A SmartNet maintenance account allows you access to download software for just about all platforms. So yes, you could download the IOS for a 1700.

I don't have enough memory to upgrade to the IOS I want to use (one that contains 3DES). I was looking for memory online and found a diagram of the router. What is the VPN slot listed here:

Is this required for any VPN connectivity?

From the Cisco site:

SecurityThe Cisco 1721 supports hardware-assisted wire-speed Triple Digital Encryption Standard IP Security (3DES IPSec) VPN encryption (using optional VPN module), a Cisco IOS Software-based stateful inspection firewall, and an intrusion detection system (IDS) that allows customers to keep their data safe.
