Hello everybody,
I want to know how to storage the DHCP IP table in a external flash of a router. This is because the router is switched off and switched on everyday but I want that it remembers which MAC is associated with which IP when it starts again and avoid IP duplicate problems. The command "lease" doesn't seem useful here.
I was looking for some info in Cisco docummentation, but finally I found nothing...
Someone knows how to do that or have another idea which help me to solve this issue?
Thank you very much in advance!
Best regards,
Marcos.

Hi,
ip dhcp database flash:/xxxx is the command you're looking for, you could also disable conflict logging in case you were not saving the database with no ip dhcp conflict logging command.

Hi,
flash:/ is internal but replace by the external flash path for your need.
Concerning conflict logging: if you don't save the binding database it's best to disable conflict logging with: no ip dhcp conflict logging global configuration command to alleviate the problems when the router reboots.
