Hello everyone,

I am using a Cisco 1760 router as a DHCP server.  I would like to know if I can get DHCP log files from the router.  I am new to Cisco, so my command knowledge is not very good.  Can the server send log files to our domain controller?  The router is running IOS version 12.3(4)T4 and I use SDM software to manage it.  I have listed the IP address of our domain controller as a logging host for the router, but I do not know what logs are generated or where they are stored.  Any advice?

The router sends syslog information. You need to have a syslog server on your domain controller if you don't already have one. I believe there's a package called Kiwi Syslog server or something like that. I've never used it.

Syslog messages are just text messages. How they are kept depends on your software receiving the messages.

Kiwi is a good syslog server, and free.  http://www.kiwitools.com

You can also export the DHCP database to a tftp server..

Thanks for the answers, they solved the problem.  I am using Kiwi Cat Tools to send a 'show ip bindings' command every 6 hours to the router and save the log to a file on our server.  It's working great.  So since I'm using both of your answers, I'm not sure how to distribute points.  Can I split them up??

Just below this box, right above the box where you would type a response, you'll see a link for "split points"

Thanks!

While it is possible to put two routes in place with the secondary having a higher metric, this may not always work. In the event of a failure that does not bring down the physical interface on the router the primary route is not removed. There is a…
