my network: pc1--SW1-SW2-R1.
pc1 is dhcp client and already get IP address from R1 (cisco DHCP server), sw1 use dhcp snooping on vlan 101, and use dhcp snooping trust for interface between sw1 and sw2, sw2 is dhcp relay(proxy).
now I got the problem, in SW1, I type sh ip dhcp binding, but there is no entry, same as SW2. so what goes wrong, thanks
