We enable dhcp snooping on the network. Is there a easy way to verify the functionalities?

Thanks.

You only have to connect a dhcp-service on an (dhcp-)untrusted Switch-Port.

Is there any command we can use to monitor the process?

Thanks.

I think that you mast install some sniffer on the computer which connected with untrusted port

and install some sniffer on the DHCP server, and compare results (sniffer maybe the WIRESHARK its

freeware)

Is there any build in command we can use? Thanks.

show ip dhcp snooping binding

will show you all the MAC to IP bindings. Is this what you are looking for?
