Newbie: Cisco 800-series - DHCP reservation?

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

! ip dhcp pool DHCP-LAN network x.x.x.16 255.255.255.240 dns-server 193.67.79.39 193.79.237.39 default-router x.x.x.17 ! ip dhcp pool DHCP-WIFI host x.x.x.x.23 255.255.255.240 client-identifier 0100.13ce.c307.92 default-router x.x.x.17 dns-server 193.67.79.39 193.79.237.39

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!

No worries, sorted it. My file is now:

ip subnet-zero ip dhcp binding cleanup interval 10 ip dhcp excluded-address 192.168.1.1 ip dhcp excluded-address 192.168.1.1 192.168.1.200 ip dhcp excluded-address 192.168.1.251 192.168.1.254 ip dhcp excluded-address 192.168.1.150 ! ip dhcp pool CLIENT import all network 192.168.1.0 255.255.255.0 default-router 192.168.1.1 dns-server XXX.104.130.XX XXX.104.130.XX lease 0 12 ! ip dhcp pool JIMDESKTOP host 192.168.1.200 255.255.255.0 client-identifier 0100.e018.XXXX.XX dns-server XXX.104.130.XX XXX.104.130.XX default-router 192.168.1.1 lease 0 12
