In my network there are 2 dhcp servers.Swith 2960 acts as dhcp server and a external dhcp server is directed connected to via cacasade to this switch. Sometime, host connected to swithc 2960, take ip address to external dhcp server, that is not good.
How can give a priority to a particular dhcp server ?
If it is not possible, can i disable dhcp service on port with cat 2960 ?
When the client sends a DHCP request it is sent as a broadcast. This means that both the 2960 and the external server will receive the request. And they will both respond. It it up to the client to decide which response to accept.
I am not aware of any method to give priority to the 2960 for DHCP response.
If you do not want the client to get its IP address from the external server, it seems to me that the solution would be to remove the scope from the external server for the connection to the 2950.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
