Object
notification
To detect unauthorized DHCP servers on a network, the DHCP snooping device sends DHCP-DISCOVER messages through its downstream port (which is connected to the DHCP clients). If any response (DHCP-OFFER message) is received from the downstream port, an unauthorized DHCP server is considered present, and then the device sends a trap. With unauthorized DHCP server detection enabled, the interface sends a DHCP-DISCOVER message to detect unauthorized DHCP servers on the network. If this interface receives a DHCP-OFFER message, the DHCP server which sent it is considered unauthorized.
