blau, i changed this and now it works: address range 172.16.0.1 172.16.1.255 But look, I still have this problem: router#show ip dhcp pool a-pool Pool a-pool : Utilization mark (high/low)    : 100 / 0 Subnet size (first/next)       : 0 / 0 Total addresses                : 4094 Leased addresses               : 0 Pending event                  : none 1 subnet is currently in the pool : Current index        IP address range                    Leased addresses 172.16.5.19          172.16.0.1       - 172.16.15.254     0                    No relay targets associated with class LIMIT-DHCP-SUBNET What should I do to reset this? ...

blau, i've tried doing what you suggested: it gives me the following error: % Specified address out of pool's subnet range when i input: address range 172.16.0.0 172.16.1.255 Thanks. ... View more

Jeff, I can't do that. Can't change the subnet. I have other devices in the range that use static addressing. I did resolve the problem for the moment. I did the folowing: ip dhcp excluded-address 172.16.2.0 172.16.5.0 ip dhcp excluded-address 172.16.6.0 172.16.15.255 and it works fine. The problem was that I had several of these for the 172.16.5.0 network: ip dhcp pool Samsung    host 172.16.5.41 255.255.240.0    client-identifier 0188.308a.xxxx.xx    default-router 172.16.15.254    dns-server 172.16.2.1 172.16.2.2    netbios-node-type h-node    lease 10 that's why the exclusion didn't work. (Although it did before. strange. ) Thanks for the input! ... View more

blau, never knew about this ip dhcp class stuff. seems like a cool shortcut. looking for documentation online right now... thanks ... View more

Jeff, Sounds like a nice idea. But can we have the two different? ip dhcp pool lsr-pool    network 172.16.0.0 255.255.240.0    default-router 172.16.15.254 . interface GigabitEthernet0/1.2 ip address 172.16.15.254 255.255.240.0 . Regards ... View more

Dear alain, Changing FROM: ip dhcp excluded-address 172.16.1.0 172.16.15.255 TO: ip dhcp excluded-address 172.16.2.0 172.16.15.255 will add 255 more hosts to the pool. Correct me if I'm wrong. ... View more

Dear Milan, That is not an issue. In fact, the network address and the broadcast addresses should never be assigned to hosts. We had the following configuration before that worked fine:       ip dhcp excluded-address 172.16.1.0 172.16.15.255 The problem was that the amount of computers has reached the available pool amount, so we had to increase the pool. we did this: no ip dhcp excluded-address 172.16.1.0 172.16.15.255 and now we have a huge pool and all computers on the network are able to get a proper DHCP configuration. (problem solved) But we would still like to limit that range for now, by applying: ip dhcp excluded-address 172.16.2.0 172.16.15.255 (this is where i get the error) (So basically add another 255 ip addresses to the pool) Thanks. ...
