DHCP Cisco 800

[ElwinMkanyika]

Guys!

I got a dhcp client on the rumpage here! Below is what is configured on the router but for some reason, there is a constant deficiency of addresses yet that should not be the case since the pool has more that what is needed! Whats wrong ?

ip dhcp excluded-address 192.168.5.200 192.168.5.254

!

ip dhcp pool DATA-dhcp-pool

I don't see any problems with what you have posted up here, everything looks good. Could you describe your issue in a little more detail? When does this happen? Is there a particular device that has problems?

#sh log

*Feb 21 08:42:23.631: %DHCPD-4-PING_CONFLICT: DHCP address conflict:  server pinged 192.168.5.3.

YET if you look at the offered address, 3 is not in use

=============

The problem was that clients were trying to get an ip address but they could not get it - always showed conflict yet the address was not in use. I seem to have solved the problem somehow. What i did is i deleted everything regarding dhcp then reconfigured it again. Now i do not see the problem.

DHCP address conflict: Means somebody is using that IP have u figured who was using that IP.

Thank you Jawad, Alain and Gregory!

Apparently there were static assignments that i did not know of.

Thank you all!
