Abstract
A mechanism is provided for identifying a snooping device in a network environment. A snoop echo response extractor generates an echo request packet with a bogus MAC address that will only be received by a snooping device. The snoop echo response extractor also uses an IP address that will cause the snooping device to respond to the echo request. Non-snooping devices discard the echo request packet. Upon receiving the response packet, the snooping device is identified.
