Hi. The devices we are using as DHCP are cisco switches 6500. They are sending a conflict message:
Sep 24 08:38:28.249 COL: %DHCPD-4-PING_CONFLICT: DHCP address conflict:
server pinged 172.22.3.125.
This message had appeared with a lot of addresses..

If we have two DHCP servers, how the servers knows which IP was assigned by the other server to avoid these conflicts?

how many nodes are we talking about? could you have two different DHCP pools. For example
Pool 1: .100-.150
Pool 2: .151-.200
Pool 1: .100-.150
Pool 2: .151-.200
pdiazq:You have to split the the ranges that re being assigned by the servers.
