Anyone know how to save DHCP bindings to FLASH/NVRAM rather than tftp?

I have four distribution facilities, which are not large. I have Cisco routers in these sites configured with DHCP servicing the staff at each location.

The problem I have is when these routers go down, all DHCP bindings are lost.

I know I can configure the tftp option to save the bindings to a remote tftp node, but I'm hearing there is a way to save these bindings to flash.

Comments? Solutions?

Best Regards

Hello Jeff,

there is an option to load a txt file with origin command the device still makes a TFTP request but it may be able to open it to itself.


you also need to enable tftp to serve the file that is on flash.


ip tftp-server flash:staticbindings.txt

but these are like manual bindings so it may be different from what you look for.

my understanding is that dynamic bindings can be saved to a database agent that actually is just a TFTP server.

Hope to help
