- Newbie: Cisco 800-series - DHCP reservation?
- Posted by Jim Willsher on May 4th, 2006
Hi all,
I've a newbie to Cisco, but somehow I've got my 837 ADSL router
working - mostly!
Can anyone help me to setup a DHCP reserveration for a client PC? My
837 is the DHCP server, but I want to force a specific MAC address to
always be assigned a specific IP address.
Many thanks!
Jim

That's how it works for me. Make sure to add the 0100. in front of the mac-address, I think this is written down on
several Cisco pages as well but it took some time for me to find it out

Many thanks Hans, much aappreciated. I see where the 0100 comes from -
it's 01 plus the MAC address.
I tried what you suggested, but I got a bit lost! My current DHCP pool
is 192.168.1.201 to 192.168.1.250, though in reality it doesn't need
to be that big (20 addresses would be fine). Looking at your example I
need to create TWO pools. Are you able to advise me on what the
network and host settings could be? I tried entering
192.168.1.200 255.255.255.255
for host, but it said it was invalid.
Many thanks!
